Re: Model A Times Article About Not Using Diesel Oil
"Diesel oils" are formulated for both diesel and gasoline engines.
They are marketed mainly to the diesel engine fleet guys as a diesel oil, but they do also say you can use it in your gasoline engines, so you don't have to stock different oils (mixed fleet).
Here is a copy/paste of a few small excerpts from the Chevron literature. Shell Rotella T is essentially the same:
"Delo® 400 LE SAE 15W-40 is a mixed fleet motor oil
recommended for naturally aspirated and turbocharged
four-stroke diesel engines and four-stroke gasoline
engines in which the API CJ-4 service category and
SAE 15W-40 viscosity grade are recommended."
"Delo® 400 LE SAE 15W-40 is approved for:
• API Service Categories CJ-4, CI-4 PLUS, CI-4,
CH-4, SM" <== SM is spark ignition engines
"Zinc, mass % 0.13" . <== that is 1300 ppm, if you think zinc is important
I have not had a chance to read the oil article in the MAT. I requested a copy of it from the publisher back in January but have not heard back.
YMMV.
