On mobil one website they say to use 5w40 synthetic in place of conventional 1 5w40. Even at Napa I was told the same. I don't see 1 5w40 synthetic on shelves. I just wanted make sure I'm doing the right thing.
Yes, you're doing the right thing.
I know people have spent a lot of money on their tractors, cars, truck, and all their other internal combustion based equipment, but sometimes we over analyze the oil we use. It's far more important to regularly change oil and the oil filter.
