As my old timer mopar loving friend says "a ranger ain't like a ford". Meaning its probably one of the better ones made. Other than the auto transmissions anyway.
The only thing i've bought at napa in the last 10ish years has been 85w-90 GL-4 because they are the only people that actually had it in stock. Other than that they aren't that helpful. If I have to wait 3 days, I'll just order it online at this point.
