Best stuff you can get. Even a few race teams I spoke to use it. I used it in my sr for years and will continue with the LS.
P.s Royal purple is the worse shit you can buy.
ah yes and with track days i would always change oil right away lol…
‘apparently’ some of the race oils (advertised as racing oils) claim that you dont have to but i have yet to try one.
I know amsoil has a race oil of their own but no idea how good it is/etc… its probably good considering their ‘regular’ stuff works damn well.
eunos 5w40 straight from japan, #1 for sr20s
Rotella T-6 5W-40
Northern Ontario nights are cold.
Ill be picking up some 15w40 Amsoil today. I basically want my engine to last through this drift season. I hope its alright for daily use too since its also my DD.
Rotella 15w40
Do you know where I can buy some? Or 15w40 Amsoil? Anyone?
Partsource, you can also grab Amsoil 15w40 Diesel from there too lol
if anyone wants premium synthetics for CHEAP pm me ,
I grabbed some 15w40 redline diesel oil. I started my KA-T for the first time an hour ago and all seems good. Just cuz it says diesel oil doesn’t mean its only good for diesel right people? Alsong as its 15w40 then thats all that matters right?
i’ve always gotten it from canadian tire.
Or me … I’m an authorized Dealer
