Houston weather forecast 95-99
I was in Walmart and impulse purchased a quart of Super Tech 20W50 conventinal oil.
I was planning on using Chevron Delo 15W40 semi synthetic but with temps close to 100 and the 6.5 HP Kohler engine in the pressure washer running flat out for hours at a time I thought maybe the 20W50 would be a better choice.
20W50 conventional or 15W40 semi synthetic?
BTW - Kohler recommends their 10W50 synthetic
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.
