Anything wrong with using Mobil Delvac or Shell Rotella in a Gas engine?

[Pookster]

I just started using Delvac with this last oil change. Havent noticed anything wrong with it, but I figure, if its good enough for a diesel, good enough for me?

Any thoughts? Comments? Hearsay? Facts?

As long as it has an API rating that is good enough for your spark ignited engine.

Both have an SJ rating. *shrug*. Also could never figure out why mobil calls it the million mile oil.

i have ran shell rotella for the past 5 years with no problems...all our company pickups run it...all the yard fork lifts run it, and all the semis run it...with no problems at all in anything...
