    I use Motorcraft 15w40 oil. I pull an 11K pound 5th wheel, almost exclusively with it otherwise I might use the Motorcraft 10w30.

    I used Rotella 15-40in my truck. Worked great, once it was warmed up. I had the romps with this oil. Switched to 5-40 and never had a problem.

    I use Rotella T6 5w-40 and haven't had an issue. Just got my OA back from blackstone after 7800 miles and it was still in really good shape.
