Re: engine oil

Hi Parker,

The 1931 lubrication chart in our Technical Page defines Light mineral "LM" as a 20wt oil and heavy mineral "HM" as a 30wt oil for all Durant models. Here in California I use 20w-50 motor oil.

Re: engine oil

I've used Valvoline 20-50W racing oil(grey bottle). It's got the 50W for the "large" clearances in our engines(they also sell a straight 50W). Ross
