I do trust him and I will be using the Pennzoil. I guess it just kind of surprised me. I know he was in a bit of a hurry when I talked with him so I didn't get to pick his brains about why he goes with Pennzoil.
He did also say not to worry about changing it out after the first few hundred miles/passes.
I gotta admit - it will be nice not having to pay $$$$/qt for something finally!
