what oil in a gasser?

[panzerbob]

Hi all, what oil do you use for the oa331 gas engine?

 

[DDoyle]

The engine was designed for 30 weight motor oil in most circumstances - the tag on the dash, IIRC, mentions some exceptions. Because I have two gassers, and several Multifuels - I use the same Rotella T in the gassers that the other trucks get, and have had no problems with this program over the past 10-15 years.

HTH,

I happen to use Dello 400, 15w40, but use it in everything, reguardless of fuel type or vintage.
