Has anyone on this board actually had an oil-related failure before (not a failed oil pump or leak, but something that failed because of the oil you used?)? *pauses for a few seconds* ... I didn't think so ;\)

Pennzoil, Quaker State, Amsoil, detergent, non-detergent, multi-vis, straight vis, Ford, Chevy... this argument will not actually ever be resolved. Use the oil you want. ;\)
