whats everyones view on oils??
i have found that mineral based oils are good for running in engines (GP 50 i think it is.....) and synthetics are better for normal running and raceing (mobil 1, synth S ect...)
What are other peoples ideas/ knowledges??

yatesie,
Different engines are built to different tollerances. You really need to check the manufacturers recommendations. To thin an oil and you will do damage to your engine.

Yea, those old crappy 8 valve engines need a thickshake oil in them. Probably a 50-50 would do the trick.

I use Mobil 1 in my Supra and before then I used Genuine Toyota engine oil for the car which was like 20-50 or something. And in the mornings the car would struggle to start and the thing never ran that well...I had problems with the way it ran that I wanted to get rid of it.
Then I used Mobil 1 and the car would start beautifully in the morning and when the car was running warm, it would drive really really nicely...with the toyota oil it ran sluggish when warm.
Seen that ad with the oils and he goes 'cars are like girls, they need the best protection' or something like that!

Rattlehead, I am feeling the EXACT same way at the moment, my car has been a super-slug and noisy, hard to start without those 2 pumps on the accellerator before starting...
I might just goto something lighter, but I believe Mobil 1 would kill my car Too thin for such a battered 4AF

Marketing gimmick.
To 'stick' it would have to be thick. There's nothing magnetic about it. If there was, the oil would end up in one long strand or would clog up the peformance of the car as the rings have to scrape off the stuff sticking. Or you could throw the cat in the engine and watch the static buildup make it go poof.
Or what if you had to change the oil? Nothing would come out.
Just my personal opinion, I don't buy stuff that is sold under a gimmick.

i'm becomming a big fan of Valvoline Oils. i've tried everything from SG 20W50 ordinary mineral, Castrol Softec full syn 5W30, Valvoline Synpower full syn 20W50, and to tell you the truth, the best i think is Valvoline Problend 15W40. the 15W40 grade is great compromise between old engine, and thin oil and with the semi syn blend it's good quality and runs a treat in my 4AGE.

I was reading a thing about oils on Autospeed last night. The CAstrol Magnatec oil isn't magnetic no, but the type of chemical they use does have properties that means it becomes slightly polarised and adheres to metal surfaces. This is why it is supposed to be good on start-up.
I'm running it in my 21R-C, and the engine feels much nicer, apart from a couple of vibrations caused by other things (broken muffler, cover over exhaust manifold) my car has run really well, even cold morning dont phase it any more.

Surface energy. Think wax and water but reversed.
Magnets don't stick to aluminium.

Justcallmefrank,
Unfortunatly mate I am speaking from personal experience. That and Advice I have since received.
Rattlehead,
I think What you meant to say was "Castrol Magnatec... Its KY for your car  " Or something like that !
I have used it myself and a was quite happy with it.

Hmm,
I've got another bottle of Pennrite HPR30 (30W-60). I remember my last mechanic used a Semi-Synthetic Castrol oil in my motor... Thinking I'll try something thinner, cause this thick stuff does take about 15-20mins to warm up in the mornings before the car feels less sluggish.
Anyone else used Pennrite products? Experience?

i ran magnatec for a few months and i have to say i wasnt impressed. i dumped the oil after about 4000 ks and it was BLACK and reasonably thin. so i wont be using it again. i currently have penrite run in oil in my car as i havejsut finished my rebuild and after the first 500 km i am putting in some penzoil semi synthetic.
i will not bey valvoline oils simply because of the knob jockey John Laws

Just because the oil turns out all black does not mean it's not doing its job. It's more likely that it IS doing more of a job than your previous oil. Engine oils contain detergents that help prevent combustion by products from caking up the oil channels. The other problems may be:
1) filter not working / bypass valve stuck open
2) Over rich running
(I run Mobil 1 - nothing too good for the JZ, and two turbos = double potential trouble)

Just bought Penrite HPR 10 Semi-Synthetic 10W-50. Will see how it runs in my car. I just think Mobil one is too expensive and too thin for my engine. Hell, It burns a good 1 litre of oil every 5k kilometers...

I've put magnatec into my SV21 camry and since then its run a bit smoother but rufuses to warm up, especially now its winter. Not too sure whether this is to healthy or not but it barely reaches 1/8th of the temp guage in the city and on highways it sits below "C".

That definatly does not sound good. I'd be getting the sensor or gauge itself checked.

I'm pretty sure its the oil because i ran Valvoline Problend and it worked fine, sat in the middle no matter what. As soon as i changed over to magnatec it started doing this. Another way i can tell is that the heater (runs of the heat from the coolant) doesn't work very well any more.

Have you got any coolant left?
I'm not saying you are lying, I just don't believe that an oil can do that. Could just be a coincidence when you changed the oil something broke.

I've not noticed it taking any longer to heat up, my gauge is faulty (reads higher than it should) but still gets up to temperature quick. I'd check it with my heater, but its not working

I remember once reading in motor that thicker oils can retain heat better than thinner oils, because thinner oils radiate heat more quickly. As the oil is thinner i thought is could be that. I've got plenty of coolant so i guess the next check is the sensor. now how do i get to that.....

Oil in my 7MGTE
|
Sun, 23 June 2002 12:05
|
|
I used to use Mobil 1 synthetic because a mate of mine gave me 20 litres for free cause he works at a mechanics workshop.
I had been told it was too thin but ignored this advice.
Oil consuption was fairly decent cause most of it was going past the turbo seals when it was cold.
I now use GTX3 which is thicker and better suited to the tolerances of the 7MGTE which was designed before synthetic were available.
I have a question to you guys out there,
I have never seen my oil cooler get hot. Apparently Toyota do have oil thermostats but i'm not sure if they are in the 7M.
Does anyone know?

About Magnatec..... From my primative understanding of the oil, it seems to me that it probably going to be no better than another brand oof oil, wiht the same rating (if not worse). My reasoning is as follows....
For the oil to be magnetic, it must contain a metallic and magnetic substance. And for all intents and purposes, this substance would more than likely have to be iron. Now.... most blocks are cast iron... pistons - an aluminium alloy or in some cases steel rings, not sure.. but think a steel of some sort. If however you have a alloy block and you are using magnatec, with its iron content... then common sense says that the oil will wear out you block rather than protect it (being as how iron is harder than and aluminium alloy). Also, the oil will probly strat to wear other parts, sucj as the rings (??) mains, and big ends as those engine componants are softer than steel.
Adding to this.... oil finters are designed to take most non fluid particals out o fhte oil, so unless the magnetic componant of the oil is molten (i.e. about 1000 deg.) then the filter will start taking that stuff out of the oil, also with the aid of magnetic pick ups in the filter and drain plug.
Anyone got anything to add/take away/ abuse me about??

Of course there is no iron in it. It's already been concluded it isn't actually 'magnetic' as such. It's just the viscosity and the surface energy of the chemicals they add to it that makes it 'sticky'.
As I said earlier, magnets don't stick to aluminium.

I'd have to agree with ToyCam Steve. My car (7AFE corolla running magnatec) does warm up to normal operating temp. but DOES take allot longer to get there. Its is much easier to start when cold but takes longer to warm up.
It tends to rev out easier too.
When you guys say dont use oil thats too thin, whats too thin? What problems did you experince Rod?

There is nothing magnetic in it. There are certain compounds that can polarise themselves, these are the ones that are found in Magnatec. This is what makes them adhere to the metal.

Not trying to make myself look good, but i find it hard to believe that the magnatec sticks to things like ring, rods shells ect. If in fact there is polarised elements in the oil, then i couls agree that it will stick to parts, but even if they were (chemically) polarised, then the parts must also be (chemically) charged, and the charge of most metals is uniform, and negligable. For electrically charged, the block (ect) would also have to be electrically charged consistantly. BUt the oil cant really be constantly charged. if the oil does stick to engine parts, this is probably more due to high surface tention, low film strength, and high viscosity (or possibly some additive like engine building lubricant). I think the thinner the oil, the better, as long as it has an adequate film strength and fast bubble recovery time.
I am a sceptic, but also educated ( i think they come hand in hand)
I am interested to see if anyone has anything to add to this, as i have only just started being interested in oil technology...

That you said in that first paragraph is enough to not even consider that oil for a millisecond now.
You want your car to warm up ASAP. That is when most damage occurs is when the engine is cold.

Ah crap, im doing serious damage then. i am pretty sure my sensor on my 3S-FE is working cos it'll sit at halfway if it's been idling or in traffic, but as soon as the traffic opens up or im on the highway it drops back to the bottom of the gauge. Oh well, if it goes, good excuse to put a 3S-GE in....

Oh ok, if it actually does do that, then the sensor should be fine.
I see it as a good excuse to try a good quality full synthetic oil like mobile1.

On the topic of oils...u guys use the fluids u can buy to help make ur engine last longer, no need to change oil often etc etc etc???
I was looking at one at said it lastest 70,000k's or something, it was packaged in a nice black box and costed $60. What do u think of these additives???
I dunno if these things work or not, but I don't buy those coz I'm more than happy to flush the oil etc...
I use fuel additives when they are on special...like the valvoline stuff, which had 2 injector cleaners for $8 at kmart.
I was reading up the middle somewhere about me saying something about Magnatec oil??? WT...?
Anyway, when I was reading it, it just seemed like a load of bs, so I never bought it...it was on special at auto1 and my mate uses it in his XR8 and swears by it. I just went for the more expensive one...but I think theres a caltex one for $70 for 5 litres. I never tried that one.
What happens when ur car is cold and u drive it straight away? Does it do damage to the engine? I pressume it would but what kinda damage are we talkin here? I drive it cold straight away when I really need to go straight away, but I like to warm her up before I drive.
I use Mobil1 in a 1G engine and they are like 70's engines or something and it makes the car drive extremely nicer then thicker crap and doesn't get as hot.

The basic problem with driving a car hard when its cold is the fact you have metal bits sliding over and around other metal bits. This happens real fast, even faster when you cane it. The basic problem is that when the car is first started, this is happening without there being much/any lubrication...which makes this wear and thats bad. There

I don't know about your cars but mine warms up much quicker when I just jump in and drive, keeping the revs < 3000rpm...
I suppose that the transmission being used will warmup the cooland flowing thru its passages and contribute to warming up the engine quicker than if the motor were left to idle and fast idle in the driveway in the mornings.
It is also impractical for me to leave the car idling in the mornings. I believe that by simply taking care not to rev the engine into the higher areas of the range as I did when I first got my P's  that it is not doing the engine harm.
Surely there has been research done on this topic?
My 2 cents anyway, feel free to correct/criticise.

I havent done any research but when I first got my car, I caned the crap out of it coz it is slow. One time I got fed up with it (I thought all MK3 Supras had 7M's) so I thought I was gonna change the engine anyway and I started it up and then I thrashed it....did this like nearly every morning I had to go somewhere.
Usually it would automaitcally shift at 7000rpm, but this time it kept going and it went from 5000rpm to 8000rpm really quick and it made weird noises to the car. Then the engine sounded louder...now at high RPM it makes weird noises and it seems to come from the pod filter (I dunno!!! But it's not healthy sounding).
So that's my current experience with this car...I use to own a Camry as well and I could drive it cold without problems...it actually drove nicer cold.
And I notice that if I have to drive right when I start the car, it would take a minute to warm up a lil bit (depending on weather) but when it's extremely cold like yesterday morning it would idle at 700rpm in about a minute of driving around. I also note that this has happened since using mobil 1 oil.
I got my power steering fluid changed and now it makes weird squeeking noises when the car is cold. Anyone know why? Is it coz the fluid is cold or something?

I have actually been told that it's better to start driving than to let the car sit idling to warm up. Of course you must drive very sedately, like don't take it over 3-4000rpm.
You got to think about how hot the parts inside an engine gets, and then think about how stuff expands when hot & contracts when cold. The engine's built to run hot, so when it's cold there are bigger (or sometimes smaller) gaps inbetween the parts. If you start thrashing it cold, the engine will wear out real quick, cos everythings flapping around heaps more than usual.
Another thing to remember is, just because the coolant is hot, doesn't mean the engine is. This is where an oil pressure guage comes in handy, as the oil pressure at idle will start at around 60Psi, and drop down to 20Psi when it's hot. Once it's dropped to about 30 (at idle remember) that's when I start thrashing it.
As for the expensive oil additives, I was actually talking about these today at work. I'm sure a few of them help oil do it's job a bit better, but there's no way any additive will make oil last for 70,000Ks. That's fuct if one of them claim that.
Even if I spent $60 on an additive (which would be ontop of $50 oil) I would still change it after 5-6000Ks. Well, maybe I'd wait a little bit longer........

rvrolla,
I had a 4AGE that was fed on Mobil 1 its whole life that spun a bearing at less than 10,000k's on the motor. The oil I was using was just too thin and not doing its job.
I have also rebearing Tina's 2TG after somehwere around 15,000k's for the same reason. I will be running BP course plus in Tina's from now on. A friend has been running it in his 2T engine for 400,000 K's and the internals were great when he rebuilt it to take the 2TG head. BTW this engine is regularly rallied !

Whats the grade of the BP stuff your talking about Rod?
And what was the grade of the Mobile 1?

I don't know about your cars but mine warms up much quicker when I just jump in and drive, keeping the revs < 3000rpm...
I suppose that the transmission being used will warmup the cooland flowing thru its passages and contribute to warming up the engine quicker than if the motor were left to idle and fast idle in the driveway in the mornings.

Yea, just leave it for a few seconds to start the oil pumping then just drive. As been mentioned, don't cane it until it reaches operating temp. It's just a waste of fuel and it can overheat if you leave it just idle.
When you first start a cold engine, the coolant doesn't get pumped. The thermostat stops it moving. Once it heats up, the thermostat opens and lets the coolant flow through.

I've been running for BP corse plus in my 3t-gte for awhile now. So far so good. But suppose hard to know until later down the track. Spent a day thrashing it around wakefield and still looks clean.
I ran mobile 1 for awhile and the oil pressure was always quite low. With the BP corse plus it sits higher. Suppose because it is thicker.

I once blew my dad's EB Fairmont's thermostat gasket caining it whilst cold... Would this be becuase the themostat was closed and the water pump would have been pumping it too hard?
Scared the shit outta me, coolant flowing out of the cam cover side

inertia: Ive got that penrite HPR30 in my car at the moment, and as said, it takes a lot longer for the oil to get to operating temp. at 2500 rpm when cold, oil pressure is up around 80psi!

The oil you use depends on the age and condition of your engine. The older T series engine cannot be treated the same as say a 3S series. The addition of multi valves and higher rpm etc call on different oil viscosity and additives. Older designed engines need thicker oils and Mobil 1 is an oil that shouldnt be used in older engines or non multi valve ones. It is far too thin and will not keep an adequate film to protect the bearings. Rod found this out the hard way!! i have used Penrite hpr premium in my 3TGTEU for its entire life and had no problems. The one i use is designed for turbo diesels and petrol engines and is high in detergent. This helps prevent carbon deposits which can cause premature wear and detonation!! Both nasty engine killers.
No matter what oil you use if you drive hard it should be changed (along with the filter) at around 4000km. I change my oil and filter every 2500km. I do this because the oil is higher in detergent and so it cleans out more carbon, however itf left too long it would start to wear the engine. My oil is always clean when it comes out and it never gets hot.
About what was said earlier, just because the temp gauge says warm doesn't mean the engine is.... that is 100% correct. It takes 11min of driving for oil to reach its operating temp where it actually starts to clean the engine. Before this is is just there to prevent the parts contacting. Most cars will reach operating temp within 5 mins of driving but if revved too hard will still cause damage for a further 7 mins. If you drive hard i suggest the fitment of an oil temp gauge then there is no excuse for not knowing the temp of your oil.
P.S: whoever suggested that their is IRON in magnetic is a wanker and obviously has no idea. Magnetic oil is very good and it is due to ironisation that it "clings" to the engine parts. It is in no way "magnetic" as such.

Haha, that was me wiht the Magnetic bit... i was being cynical, because the name, and comon thought portrays the oil as being magnetic. But after some research, it seems it is molecular attraction which exists in very similar strengths as molecular attraction between water molecules, and i doubt it will be strong enough attraction to oppose gravities effect over more than a week or so... The attraction isnt close to the strength of magnetic attraction. I am still not wanting to trust the oils claims at the moment. Any decent oil will remain on important pengine parts for about a week or so, so i really dont see any advantage by using magnatec. Any brick with half a brain would turn there car over until oil pressure is sufficient without plugs connected if the engine hasnt been run for more than a week, magnatec or not. Although magnated isnt expensive, i would prefer to run a fully synth (mobil ,penzoil ect.) , even if i have to pay an extra $20.

No worries. magnetic aside it is still a good oil. Depending on what engine you have synthetic oil may not be suitable. In alot of cases mineral oil is better espescially older engines.
Just be careful what viscosity you use.

raistlin: Who said to keep your motor over 3000rpm when cold?? I can only see people in this thread saying to keep it UNDER 3000rpm, which is perfectly feasable to me. As you said, you'd be crazy to go revving the tits off the motor when cold.

Hmms - havinf used magatec since last oil chance i have to say im not to impressed with ti compared with the last il i used which was a Penrite or penziol synthetic .. it hink it was a 15/50 one - and my 2tb after rebuilt ran beautifully on it ..
I never really open up the motor even with giving it a play - so wear wise im sure the internals are still good though i have noticed the magnatec is turning darker quicker than what the penzoil did over the same distance ..
Ill probably go back to the other brand next change - just for the smoothness of running factor

I've put magnatec into my SV21 camry and since then its run a bit smoother but rufuses to warm up, especially now its winter. Not too sure whether this is to healthy or not but it barely reaches 1/8th of the temp guage in the city and on highways it sits below "C".

Steve,
Check/Replace your theromstat as it's a common problem in the 3S-FE. I thought at first that the radiator was super good but realised it wasn't that but the thermostat not doing its job.

Anyone have experience with Helix Ultra?

). A filter every 5000km of course. You can't have an oil lubricating "too well" that's what it's there for, to lubricate!!! The only reason you'd have probs is on an old engine which has probs with rings(or other stuff) or one which hasn't been run in properly. If you're blowing smoke(the blue colored stuff) you're getting oil past the rings so you need to go a little thicker. If not, run as thin as possible unless your engine asks for something specific or is old and shitty as i said.
