Any current VOA of ST 20w50? I would just RETURN IT.
I'd take a spec'd diesel oil over any unknown entity.
I'd take a blend over a conventional, and a synthetic over a blend. So, that would be two votes for the blended 15w40 over the 20w50 conventional.
Since Kohler recommend 10w50 and a synthetic at that, and you're in a warm climate, Walmart has 5 quart jugs of M1 15w50. That would be my 1st discounted choice. My 2nd choice would be any 50 grade full synthetic V-twin motorcycle oil that still cheaper than Kohler 10w50.
If the sump is too big, the engine might last too long. How will I make money if I don't sell enough of them often enough? So... no 1 quart sump for YOU ever with your small engine.
Just look at lawnmowersgeneratorsPSIwashers... and other small engines with their 8, 12, 14, 16, 18, 20, 24 28... ounce make believe sump capacities when a quart would've been just too easy.
I wonder if those race engines would even survive a typical soccer moms year round hyper commuting in the minivan or SUV? with start/stop enabled? So, I don't ever compare my vehicles, or my small engines, with super duper race engine running whatever or however. Yes, its a pressure washer. Nobody cares how it relates to my Toyota, VW, or a race engine, their visc, oil temps/psi, or engine misengineerings.
I will run the pressure washer for about 15 hours total - then change the oil and put it away for next year - next time I will just use SAE HD30. That was my original plan -
When I first ran the 20W50 I thought the engine was not reaching the same RPM - like the throttle was stuck - engine just seemed quieter - but the pressure at the sprayer end was the same - can heavier oil make your small engine run smoother and quieter??
I did not think it could ------------
Could be my imagination - 65 year old working his ass off in 99 degree temps - I honestly did feel dizzy a couple times - drank about 1/2 a gallon of water - but went all afternoon without taking a P - so maybe I was delirious!
It sucks to get old - use to work like this for 12 hours straight and not even think once about stroking or heart attacking out!
