Hi, I've done a little bit of searching and haven't managed to find anything really close enough to an answer to make me comfortable relying upon it. Therefore please be nice if this has already been answered.
Anyway, I'm driving a 2014 BRZ with ~8000 miles on it and am thinking I should change the oil again before too long. This car sees use as a daily driver and also on the track every few weeks. In terms of the engine it is all stock except for oil catch cans. On the track I am regularly seeing oil temps in the 125 C range and repeated hard accelerations has gotten me up to 135 C (all of this on cool to mild days). I am going to get an oil cooler installed in the next few weeks which should keep the oil temps down a fair amount (Hopefully to less than 110 C). Also I live in a temperate area so I don't have too much exposure to extreme cold temps though some of the tracks I go to get pretty warm in the summer.
For the engine oil the manual calls for SAE 0W-20 ILSAC GF4 or GF5 (also says the oil should say "Energy conserving" or "Resource conserving" if that makes any difference). Currently I am using Amsoil synthetic matching those requirements. Is there an oil that will do better for my use case? I don't mind spending more to save alot of trouble and cost down the road.
As a side piece, I am also thinking of changing the diff and transmission oils. The diff calls for "Differential gear oil LX" or GL-5 75W-85 or GL-5 75W-90. The manual transmission calls for "MG gear oil special II" or "API GL-3 or upper grade and SAE 75W-90 specifications"
I think I am putting this car through some rather unusual conditions so I really appreciate the assistance.
