OWS Castrol Amsoil...
used all...all seems the same... whoever tells u change to amsoil can make ur car faster ( thats what the guy who sold me the amsoil said) ... is like saying armageddon has hit tuas and coming to orchard soon...

in conclusion i got no doubts abt its engine protection as my engine noise has reduced, but i unsure about the 7quarts. my amateurish 2cts worth. =)
