Hi Ironbark
Yes I see now, sorry it didn't help that I had a guy jump down my neck the other morning that I put detergent oil in his mower. Was 100% adamant it was now going to blow up for those reasons outlined.
Havent pulled down any small motors that I know were run on ND or not, so it would be an interesting test. Though since an old briggs will run all day on 2 tablespoons of oil sludge, it may be a moot point
Wce, bet it will absolutely smash the grass
