Years ago, I ran a small engine repair shop. Today, I still occasionally do repairs and I have noticed thangs haven't changed much.
The vast majority of engine failures were---are-- oil related. I have seen quality machines, 5 or 6 years oil, with paint still on the drain plug!!! Mower deck spindles and other greese fittings completely dry or covered with thick dirt!!
I bought a quality gas welding machine --generator that wouldn't run, from a friend and discovered oil was original but too low to start.
I flushed the BLACK oil, ran it for a few minutes and then changed it again.
Luckily the engine ran perfect and it was sold for over twice what I paid.
I believe many people think just because it hasn't run but a few hours, the maintenance is not necessary.
