Protect your investment, worth the cost.
My diesel is getting old, no problems just wanted that little extra protection for summer months, always used the oil for 1999 F250 7.3 Diesel. Run around 6000 miles between my oil changes, I use a bigger oil filter than OEM Ford. I do put actives when changing. No problems with order. This truck was my work truck, and now my retired truck. 210K on it now and towed a car from Cal to TN with no problems, with the protection this oil provides.

Was Recommended for MEP-803A Army Generator, Seems to Run Well on this Oil
Bought this oil because it was recommended for my MEP-803A army generator. Seems to work well and I think is lower friction than the original oil, because I noticed I needed to turn down the RPMs slightly to get back to 60Hz. Possible improvement in fuel economy.
