Topped off Honda ATV crankcase with 2 cycle oil

Topped off Honda ATV crankcase with 2 cycle oil about 1/3 of a quart, any worries?

On purpose or by accident? Needless to say, not ideal

Not the best, but probably won't hurt anything, make sure you use some wet clutch oil next time.

Just grabbed wrong one when finishing up, about 1/2 quart. The rest was syn.

I'd change it again.

Change it again.

Roll with it. If it works diluted with gas it won't hurt anything mixed with oil.

I wouldn't be able to sleep at night if I didn't change it. I guess if the ATV isn't worth much and you don't care what happens to it, you could leave it in.

If the clutch starts slipping change if not I would leave it

Why?

The 2 cycle oil is still engine oil, but if it bugs you, go spend $11 ona jug of delo and sleep well. I'd run it and see if it acts normal, its a small amount to worry about.

So is old school castor R series engine oils, but if you mixed them with other oils, bad things could happen.

I say dump it and refill with proper 4 stroke oil.
