Is anyone running 15w 40 Rotella in their trucks, just wondering because we run that in all of our dump trucks so we always have some on hand.

Thanks,

J.R.

RE: oil

Mine is also stenciled 15w40 and I plan to use Rotella on the next change. It still has military oil in it now.

I use 15W40 Shell Rotella and Baldwin filters in all my trucks with great sucess.I use Shell Rotella because it's avaliable in 55 gal drums at my local Sam's club.A 55 gal drum lasts me about 2 years.

Personally I use Chevron DELO straight 30w, but for cold weather I'd use DELO 15w-40. I'm a locomotive engineer and at Los Angeles' yard's diesel service facility they have a 10,000 gallon tank of DELO 30w. DELO = Diesel Engine Lubricating Oil, and if it's good enough for 4,500h.p. V-16s, then it oughta be good enough for my little straight 6. Costco usually has the best price on a case of 6 gallons.

All the major oil companies formulate a diesel engine specific motor oil, and unless I saw results from direct comparison tests using SAE/API standard testing showing otherwise, I would believe that they're all essentially the same. The specific brand you choose is a matter of personal choice / experience / availability. These are all 15w-40, heavy duty diesel engine oils:

Shell = Rotella
Texaco = URSA
Chevron = DELO
Valvoline = Premium Blue
Exxon = XD-3 Extra
Mobil = Delvac

Synthetics - Red Line, AmsOil, Royal Purple, etc. - may be better, but I prefer to use regular dinosaur juice and change it every 12-18 months or so.

2cents Regards,
Jon
