I don't have an IR gun at home, so I don't know any operating temperatures. 48 total hours on the new replacement engine. It was indeed a 50/50 mix of Kohler 10W30 SJ & Honda 10W30 SM oil.

Not wasting oil. This is a perfect example of how UOA can be misleading due to particle size limitation, of ICP in this example. This was the 2nd change on a new engine. The oil was gray with just 5 hours on it. The next change will be longer, maybe 8-10 hours. Remember, there is no oil filter on this push mower.
