Oil Pressure Issue?

Yeah that makes sense. I knew the part about when the oil was hot it was the second number, but the rest was kinda fuzzy. lol

And I remember sellin 10/50 in the local speed shop when I was a kid. Funny you brought that up. I think I remember Valvoline made it too.

Valvoline had it too. Like I said, price point killed it. Pretty difficult to get a spread that far from winter grade to running grade.

Luck for us, WWII produced some very cool tech, especially in lubrication (and hundreds of other technologies) that would have come along decades later, if not for the war. Was the war worth it? IDK, I'd leave that up to the MIC and the king makers to determine that.
