Please refer to above sticky tread: Maintaining a Skyline (how to?) by tread starter: Supremusguys,which engine oil 2 b used for gtt?and what is the suitable viscousity?
trust me when I say, dont use this oil if your engine is stock... the viscosity is too thick, you can actually lose some power... high powered race built engines that undergo long periods of high revs could probably benefit from this kind of viscosity, but not a daily driven carEngine Oil -apexi N1 Oil 5W-50 Or Blitz S3 20w-50
L.S.D/GearBox -Kaaz 80w-90
depends on what oil you are using too, ester based oils (motul) give me lower peak temperatureby the way, what engine oil temp are you guys running on your rb26??
i'm getting 100-105 at normal, but around 120 under heavy driving.
on track, may even go up to 125...
i dont have an oil cooler, maybe thats the reason??
