lawn mower oil question

[unknown angler]

Been using SAE 30 for years changed once a mowing season, no engine failures. Most of the time the rest of the mower falls apart before the engine.

I just bought some amsoil small engine oil last night for $11.30/qt. Yikes!! I'm sure its the same as regular oil, maybe not. If anyone knows , explain it. I just figured 100 hrs of hard running its worth it.

Just run regular oil at weight your manual calls for .

I was the engineer for building small engines for 30 years, around 80 million of them. I usually run 10/40. Every engine was test run after being built with 30w in the crankcase and av gas for fuel.

Im interested to know what brand oil you use in your small engines.

Band doesn't matter, all motor oil has to meet the same specs.

I always use 10-40, no issues ever.

My manual calls for 10/30 for the outdoor temp range i mow in.
