Running RP 10-40 in my fox-body 5.0 but was considering a switch to Valvoline Max Life for the additive package. Engine builder recommended Kendall dino 10w40 but eventually switched to full synthetic after break in. Car is driven then parked for months at a time. No leaks, no consumption. Engine builder has since passed away years ago(rest in peace Bob Pucel).
Was considering different oil because the engine was rebuilt 16+years ago(aftermarket intake, cam, rockers and of course aluminium heads and aftermarket cats) and oil technology has changed. Cost not a consideration since it doesn't get driven that much(so sad).
Thanks for reading and responding.
