It doesn't. Your rings must be going, or a blow-by. You're lucky the Previa has a back up oil tank unda the hood :)
I CHANGE MY OWN OIL IN MY 1991 PREVIA. 5W30 IS WHAT I HAVE USED FOR YEARS. PREVIA JUST PASSED THE 334,000 KM MARK
i found out that synthetic 5W-50 is an acceptable replacement for the super expensive Toyota supercharger oil
Castrol 5w50 full synthetic
i think the supercharged models use premium
yes it will fit... you can total use it...
Superchargers use a special type of oil that you can get from the dealer. I bought a small oil canister for $50 OMG, so expensive but need it. Hope that helps. I use GM supercharger oil in mine.... it runs about $12 at a GM dealer and comes in a pretty good sized bottle.... I read that it worked, tried it, and have not had any problems....
