So I know the only readily available full synthetic off the shelves is the 0W30 Castrol (German Car Formula). There's also Redline and Amsoil. What about using LAT based oils?(that stuff is in there forever) even if you change the oil on next R&R you can see it draining out. Any advantages to using real synthetic fluid?- Has anyone sent their oil to blackstone? Since the OEM Toyota 0W20 isn't full synthetic as far as I know??-
Seriously you haven't heard of lat oils and you want to tell me about searching and black stone, LAT Racing Oils | Best Synthetic Motor Oil, Racing Oil, Synthetic Motorcycle Oil, Gear Oil, Break-In Oils and Engine Oil Additives
Is Toyota 0W-20 SN made in heaven? - Bob Is The Oil Guy They're saying Subaru is the closest to GF5, and those that are into rotaries or high power high strung engines know that LAT oils stick to metal like no other, even after a R&R with another fluid you can still tell LAT exists/or has existed in that engine.
