Engine Oil Change Kit, High Performance, 1967-91 AMC, Jeep V-8

P/N AMP-PEOCK American Performance offers this convenient kit to ensure your AMC engine is protected!  Unlike other domestic V8's, AMC V8's lubricate the rear of the engine first.  This requires high oil pressure to survive and operate properly.  That said, it' CRITICAL your AMC V-8 engine is protected!  Vintage engines require high levels of Zinc to prevent premature or excessive cam lobe and internal engine wear.  While many disagree on the proper amount, we've consulted with a top petroleum engineer who helped establish the standards by which modern engine oils are tested.   He told us you need at least 800 PPM (parts per million) of Zinc and 1,200 PPM of Zinc is ideal.
