5.0RR

If you have the track pak on a 5.0 you need 5w-50...per manual.

KP Racing

Run 0w-20 at wide open throttle for an entire tank of gas and blow your engine and bring it here so we can build a stronger one for you and add turbos and build your transmission and upgrade your suspension and set records and marry models




ha. In all actuality, the difference between running 5w-20 and 5w-50 in a stock to mildly modified car won't affect much of anything. I'd run what is recommended for regular use and perhaps 5w-30 for spirited driving.
