Anyone tried the new Mobil 1 SUV/Truck? From what I understand it is the same, or very similar to Delvac 1. It comes in 5W-40 with a yellow cap. Anyone give this one a try? I normally run M1 10W-30 mixed with 15W-50, but always willing to try new things ;-)

 

I just put it in this week. And from what I read at www.bobistheoilguy.com it seems 0w-40 would have been a better choice.
I wish Patman would bring his opinion to the table, I had been using 10w-30 in my 70k mile '93 Formula as well as my 185k mile '96 Blazer before I switched both to the M1 5w-40.
