I have a 1977 Johnson 70 HP. I have a 6 gallon fuel tank. I had 3 gallons of mixed fuel in the tank, and topped it off with 3 more. I forgot to add the oil for the new 3 gallons of fuel. I trolledfor 2 hours with 2 short wot runs of about 1 mile each. Everything sounds fine, runs fine, no issues that I can see or hear. Did I hurt it at all?

No, but run it again as soon as possible with 50:1 mix.

100:1 is not adequate for storage; not enough oil left on the moving parts.

Say your prayers??

Lessee, as I figure it, you ran it on 88:1. That's better than the 100:1 that they recommended for awhile, then changed their mind and recinded it. You probably got lucky, but don't be doing that any more.

Are you saying there could be some damage?

No, I didn't say that. I mean it wasn't as lean as it could have been without damage.

I have no way of knowing the condition of your motor. But it probably is fine. It also could have pre-existing damage that is totally unrelated.

Run it and sleep well, It probably is OK.

Chances are that all is still well. Don't make a habit of doing that though !!:eek:
