I am about to break out the pressure washer for my annual battle with sidewalk, driveway and patio mold -
Houston weather forecast 95-99 degrees for the next two weeks.
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.
So what is the BTOG consensus for oil under these conditions?
20W50 conventional or 15W40 semi synthetic?
BTW - Kohler recommends their 10W50 synthetic - so 50 weight is an approved oil. But for $25 a quart they can forget about that. The ST 20W50 was $4.24 a quart and I can buy 5 quarts for ~~$17.
Full disclouser - I don't recall which thread - but someplace on this forum I have stated I would never use a 50 weight oil. So maybe an old dog can learn a new trick!
