Gas/Oil Mixture ?

What happen if your motor reccommended ratio is 50:1 and let say you have been inadvertently running with 100:1 for the last couple of years?

Was your motor on of the '80's motors that were originally spec'd for 100:1 ?
I'd say if you ran it frequently enough, and used decent quality oil, that you did no damage to it. The problem (as I understand it) was that there was not enough oil at 100:1 to provide a lasting oil film on the internal crankcase parts when stored for longer periods of time, and sometimes components rusted.

I am curious to know ... Was that with petroleum oil or synthetic ?

If it's still running well then you lucked out !!! Change to the correct mixture and enjoy the motor.

To answer all questions so far except mine. It's a late 90's Mercury, been using mostly Quicksilver but have been using Penzoil as of late because the Quicksilver gotten expensive, ran at least once a week April-October, no real workout or anything but did get WOT from time to time. I don't think either one of the oil is synthetic and the motor is still running strong.

If the compression is good, I wouldn't worry about it. I would, however, switch to a 50:1 ratio.
