It is the one a lot of us use... Is there a particular reason you need only a synthetic? ... or is it just to make yourself feel better by spending more $$ moneys on oil?

would depend on your operations and climates that you frequent.

-- the next Q. would be "are you replacing all your gearbox oils at 250k miles (or equivalent hours) or every 2 years ... whichever comes first, usually at the same time you re-torque all your hub bearings and do all the other 250k truck maintenance ... like you should be?

The only reason I was thinking synthetic was because of the amount of miles between drain intervals.But as far as having a preference I don’t.Motor oil is going to be conventional and the OCI will either be 10 or 12k.Haven’t quite decided on that one yet.

Just got the truck.But I will be replacing and re-torquing every 250k going forward.
