Rear End Fluid
I noticed that a lot of the perfromance shops use the non-synthetic
GM oil for the C5 rears but the owners manual specifies the GM full
synthetic oil. If the oil gets changed every year and I frequent the
drags what oil should I use in the rear ? If I was primarily concerned
about drag race performance would I still use the friction modifier ?
Thanks >>>>> INTHERED
