My question I am trying to ask is "Anyone have damaged engine due to kind of oil used and/or the ratio used". I absolutely not trying to ask what is the best oil. Everyone have their favorite oil and theirs is always the best!!!!! Their mix ratio is always the best ratio!!!!!

I did not specify wearing due to bad lubrication only. Deposit can damage engine also like sticking the ring, plug the engine etc. I know all about bad oil suppose to leave deposit. My question is " Who actually had experience damaging their engine" not just someone believe that bad oil will damage engine.

I want to separate people that believe bad oil can damage engine to people that actually experienced damage that due to bad oil....which oil?......How bad? Real facts, not editorial.

People keep posting " I use this oil at this ratio and I have been running for this many hours and have no problem" This kind of posting have been around for many years, it has been repeat and repeat and repeat and repeat and repeat......and repeat......and repeat......
and repeat!!!!!! and repeat.

It is more educational if someone tell us what to avoid and why......From real experience.

I posted the same question on the lawnsite forum and so far nobody answer!!!!!! Really seems like everyone only want to say how good their oil and ratio is. Nobody have any real experience!!!!! They only want to speak, loud, over and over and over.



BTW a lot of lawncare people use Amsoil at 80:1. Just a piece of info.
