To be fair, It’s the only thing on the shelves in town (besides Rotella, and there’s varying opinions on that). NAPA doesn’t carry anything besides modern vehicle stuff. O’Reillys used to carry Mobil1 15-50 with ZDDP, but it’s gotten hard to find. AutoZone used to carry regular VR1 but now this is what they have in stock.Cripes I’ve been feeding the ‘77 cheapo 5-30 or something I had a couple few gallons of laying around. Now I feel bad. I should throw a bottle of zinc in it….
I used to use Lucas ZDDP additive with Valvoline 10-40 but then after some research, apparently 5000ppm in a bottle is way too much and can be corrosive.
I don’t mind spending the extra on it, gives me the warm and fuzzies when I fill it up with this stuff. Likely overkill, but by all indications it gets great reviews from the “experts “ and is well regarded as a good oil.
