[TOYROTA] Regular Location: A.C.T Registered: July 2002	Re: 13b into AE86 Sat, 01 May 2004 09:51 Hehe yeah that whole oil thing, it's a never ending saga. Yeah go to the Ausrotary forum and take a look yourselves, it's really a here and there issue. I've seen many cases where rotors run only on fully-synthetic oil have been stripped down after a blow to find the rubber oil seals 'dead' and seals and rotors all carboned-up from what is described by people "in the know" as not-suitable oil resulting in the dead motor. All cases i've heard and seen seem pretty convincing, the car running perfect A/F ratios, oil metering pump running correctly (not wired open lol) and what not. HOWEVER having said that, i have also seen synthetic-run motors stripped down and shown to be in quite good condition. I guess it really is an issue, both sides having many avid supporters however personally i agree 100% with the comments made by someone on Ausrotory who said, quote: "The fact of the matter is none of us have the research and development capabilities to know for sure This thread is just hearsay, anecdotal evidence, and at best, very isolated examples on single engines subject to uncontrolled external variables. Mazda say, dont use synthetics. I realise this may not necessarily indicate a *real* issue with Synthetics, but until such a time as proper scientific evidence in controlled experiments is done with proper logical conclusions you cant say otherwise. The reasons for using synthetic engine oil in this thread are fallacious." I couldnt have said it better. As said above, Mazda themselves, the producers of these engines say not to use them, but i agree with you in saying that there is proof that it can be run with good results, under what circumstances however i'm not sure. Maybe there is an issue with semi-synthetic verses full synthetic? I've seen many semi synthetics run fine in rotaries. The only other conclusion i can come to is perhaps the quality of the oils in the first place. I know "Oils ain't oils" and i am aware that there can be quite significant quality differences between what seems to be two similar products. I have only heard good things about people using the MOBIL brand synthetics in their rotaries, however have seen as said before other brand synthetics used to destruction. I mean a LOT of other branded synthetic oils specifically say on the package, "Not for use in two-stroke motors", however, Mobil state that they have done tests with their Mobil1 product and say that it is safe for use in them. I guess it really is as said before, hard to tell without sceintific evidence proven by thorough tests, so it's up to you if you want to take the "risk" as it were, in using them. I've had nothing but excellent results using the top-line mineral oils and as they say, "if it ain't broke, dont fix it!" I personally choose to continue to use these products until i am 100% sure it is safe to use the synthetic type. If you want do otherwise then that's entirely up to you! cheers, André PS, what diff are you running in your SR20-powered AE86? My friend put an FJ20ET in his and keeps blowing everything he put in it, could very well be his driving style but it does pull some serious numbers. He was thinking about a Hilux rear end, can anyone give any advice on weather this would be a good idea? Used for drags a lot but really starting to get involved in circuit work. Thanks in advance for any suggestions. [Updated on: Sat, 01 May 2004 09:55] [Report message to a moderator]
