I have a short-ish drive of 10 miles each way. No true highway for me. I have a stretch of road that is a tad over 6 miles that is flat, straight, 65mph, and no stop signs or lights. I honestly don't know if my oil get up to temp or not? I doubt it.
I am currently using PP. I am doing an oil change this weekend. I went in to get my usual jug and my local Wally was out of the Pennzoil. I went to the next closest Wally and the same thing happened. I just purchased the Mobil 1 instead. It was on the shelf at both stores. Seems to be the story for me around here. Mobil is everywhere. You can find it at any Wally, Sam's Club, O'Reilly, NAPA, AZ, AAP, and even Pep Boys. I will take convenience, good price, and a high quality product every time. Mobil 1 it is.
