I'd tend to agree with you, but bigdog asked about 10w-30 lubes, not 15w-40.quote:

Or you just have to live in a colder climate - most parts stores around here that carry much of anyhting for the diesel crowd carries a brand in 10w30 -seems to usually be Rotella though...quote:

Yes, those oils are available in 10w-30, but you'll never find them in the local store.
I'm using it in an '03 Dodge Durango 4.7 engine (Chevron Delo 400 15W-40) and it doesn't affect gas mileage at all. Have also used it in an '02 Chevy Cavalier 2.2 OHV engine without any noticeable affect on gas mileage. I only use truck oil in the summer, though. For the rest of the year I use Havoline 10W-30.quote:

Is it safe to run Delvac 1300 or Delo in a gas engine? Will it harm the motor in any way? Thanks
