Kendall semi syn Vs Mobil 1

Use synthetic oil only if you what to extend your oil changes. Otherwise, there is no advantage. Using blends does not make it possible to extend changes as they are mostly petroleum based like regular oil is. As Cavell says, just treat this Kendall oil as a regular non synthetic as far as your expectations are concerned. The biggest advantage for blends are for the seller. They can charge 40% more when they are only 10% or even less different. The m/c uses Kendall instead of synthetic because he is too cheap to use synthetic…like many of us who don’t plan on extending oil change intervals.
