Hi to All, fellas, this thread has been discussed recently sprinkled with debate and is worth re-visiting; see Gomowers post #12441 "Engine Oil for 4 Stroke Mowers" with a final post by
grumpy which says, quote:
"I suggest you completely avoid using engine oil as the oil component of two-stroke fuel. I too remember the days when we used to have to do that, and I wouldn't want to return to them. The specific-purpose two-stroke oil does not separate from the petrol the way engine oil does, and in my experience it does not grow 'whiskers' across the spark plug gap at full throttle the way engine oil does.
In both two and four stroke mowers I suggest you just look in the manual for that specific mower, and do what the manufacturer recommends." unquote.
This would be my recommendation as well.
