Delvac and Rotella both carry diesel and gasoline ratings. SM is a gasoline engine rating.

With varied results.
every engine is different.
That being said feel free to do your experimentation.
The oil manufacturer is free and clear should your experiment fail.

I'll stop here. This is what I am involved in for a living.
I discuss this stuff all day and have discussed it all at length with chemists, engineers and reps from Imperial Esso/Mobil.

Someone should chime in with regurgitated facts they read on the internet.
Listen to them. Really.

Mobil 1 5w40 turbodiesel truck oil meets SAE SM as well as the diesel ratings.

I should of specified, I was referring to the aformentioned conventional 15/40 delvac and rotella products that were intially the topic of this conversation.

The 5/40 synthetic is great for higher mileage gas engines. I put it in old hondas and volkswagons at the shop that are consuming to much between changes.

So...Delvac 15W40 is designed for diesel engine? I think I will stick to Shell Rotella.

Diesel oil formulated for large displacement diesel engine is fine for a gas motor, if you never rev it past 3500 rpm. Also the detergency and additive package is formulated for gas engine more often than not.
the "s" in api rating is for gas. "c" is for diesel.
Anti foaming/cavitation additives are not up to the task.

Mobil 0/40 has more zinc than than thier conventional 5 and 10/30.

I can provide zinc/phosphorous PPM specs for all the mobil oils if you are interested.
Highest content is in thier racing 0/50.
Next, that wont kill your converter, is the 15/50. This is what I run.

Just my two cents.

Mobil 1 syn 0w40 here

I hope you don't like your cam lobes. ZDDP on that one is pretty low.

What mileage should you start changing oil, ie what would you recommend for an ix with 150xxx miles. Cost is no object, my baby only gets the best.
