There is simply no evidence to support this claim of lesser engine life on synthetic versus conventional unless the manufacturer recommends synthetic due to high oil tempatures.
I believe you meant conventional versus synthetic since we've rarely heard the argument for the contrary.
Or I meant to say there is no evidence to support synthetic causes longer engine life over conventional. The rate most members change oil on here API SH PCMO would still have life left in it before it would be changed out.
