I was just bopping around in Wally World getting my fishing license updated.

Anyway at the risk of starting a new oil thread... Does anyone have experience using Rotella Full Synthetic 5w-40 in a gas engine. It was 13.45 or so for 4 quarts. It said it had the same protection qualities as a standard oil 15w-40. And it had the lastest "m" designation.

I was thinking about it for my sons car. He only drives about 7-800 miles a month. I noticed Mobil 1 Extended Synthetic was about 22 dollars for 5 quarts in the 15w-50 weight.

I am starting to think about the short winter period here, where I back off of 20w-50 dino for about 3-4 months or one oil change. He's on track to burn off a quart at 3200-3500 miles this go round. About the same as always. I always change at 3000 miles. Thought with the Rotella I could probably go 4000.
