I'm not sure about the small to medium thing, that fits the classification of my 2cycle engine 50 hp.
Other one is 4 stroke so doesn't count.
I would think that with these "newfangled lean burn" 2 cycle engines (e-tech) there may be a new class of oil they require.
Do you have an older engine or one of the new ones? Older engine should be ok.
Anyone got one of these E-tech engines?
