Ive just had a light rebuilt of my 4agze with rings,bearings and hg.
After long periods of searching i still cant decide which oil to use now.
I was previously using penrite HPR15 but now that its fresh.
I think i may change to a fully synthetic
I used Mobil 1 for about 3 years in my 4AGTE and now use HPR10. On a fresh engine with the clearances all in order I would imagine that Mobil 1 would be fine.
Using the Mobil 1 or whatever you choose is for after you have run it in though
yep its done oiver 1000kms nows so i guess its run in now.
I read and hear people using this type and that type of oil but what i really want to hear is a reason they are using this oil not just because everyone else is using it and its synthetic its good.
Well I used Mobil 1 becuase I read and heard that it is a good product. Seemed fine, the hardest workout it ever got was track days and I had no problems.
I use HPR10 because my tuner recommended it and it's cheaper than Mobil 1 which is a good thing when oil changes are done quite regularly The only noticeable difference between HPR10 and mobil 1 that I notice is quieter start up with the HPR10.
My thought on this topic is that very few of us will ever keep an engine long enough to know if oil x or oil y minimised wear. Regular oil changes will be more beneficial than using a particular brand.
Use one of the major brands in the correct weight, change it regularly along with your filter and I don't think you can go wrong
What weight is the 4AGZE meant to use as stated in the factory manual?
