I think I'll continue to use Sea Foam as well. I've owned my truck for only six months, and I've been using 87 at the pump. It's affordable.

With this small ordeal I made it through, I'm considering at least using 89. I want to at least give her better gas. I use my truck mainly as a work horse.

What octane do you guys run usually?
