The issue I have to think about is being able to find oil on the road. That's why I run Rotella-T 15-40. I don't have time to hunt down oil when I'm on a hotshot run and time is money. Rotella-T is a proven premium oil and you can find it at any truckstop. If you don't run OTR, it may not be for you.

I'm wondering if anyone has tried Mystik or Amsoil? Both are hard to find (which rules them out for me) and a bit expensive, but excellent oils under harsh conditions. The people I know that run them in big trucks love them.

 

Mobil 1 isn't all that hard to find, the biggest factor against it, it seems, is price. Especially if the Walmart doesn't have it. I just despise that store to a level that I can't even describe, unless not without the word filter software going nuts. Truck stops that I've been to have it, but I don't get my oil there. Why I don't know, just get fuel and snacks when I'm there.

I don't know if I qualify for "OTR" (I wish there was a different acronym for that, I always think of Old Time Radio) with doing horse shows putting on about 36-40k a year on the truck.
