With that oil you won't have a problem.I've never had an issue with the detergent oils (Amsoil) that I've used in all of my machinery. And that's been 29 years (!) and counting.
Any oil along those lines is probably fine. Just make sure detergent isn't uses in the oil.
Walmart carries the brand "Accell" (Accel?) - it's a non-detergent oil. Just look for ones that say on the bottle "non detergent." I know for sure it's at walmart.. so it's probably at auto stores too.
Note - Lawn and Garden oil is non detergent.. that's basically one of the factors that make it "lawn and garden"
Wow, I think we've beat this oil subject to death! LOL
The author of the article that you linked to actually has it backasswards.Here's an interesting read. It explains the situation of non-detergent often being used in lawn mowers (aka "lawn and garden" oils), but then it has the OPPOSITE stance for oil filters, recommending that you DO use detergent based oils if you don't have a filter. It doesn't say why, it just says "they can benefit."
Heck maybe it's just the case of lawn equipment using this oil type for so long that it has become the 'standard' without any real rhyme or reason.
