20w50 supercharger oil?
ok, ive read the tech info and the manuals on the changing of the sc oil. and all of those say to use delco part # ....
but an old timer told me that he uses and has used for many years, fully synthetic 20w50. according to him it is the same as the "fancy" oil you buy at the dealer.
is there any truth to this?
*note- i am by no means recomending or plan to use 20-50 in my sc. im just curious.
