49 8N. What might happen if I overfilled the oil by about 1 quart by adding MMO. Then I mowed for about one hour.And..... .
The tractor started to blow whitish grey smoke and spit what I hope was oil blow by from the exhaust manifold and not coolant. Please don't ask why the oil may have been too full, I had a brain cramp. DUMB DUMB DUMB It supposed to be things like this that make me wonder about OTHER people.(ha ha)
Thanks Rick T.

Thats interesting gahorN,I learn something everyday on this forum.I've been paying more for a pint of MMO than a gallon of off road diesel costs for a fuel additive in my tractor and flat fender jeep.I removed and cleaned the gunk from the tractor oil pan,rocker arm cover,and push rod cover,then refilled with RotellaT 15w40 and a quart of MMO.The oil was about black after 10 hours,but the blow by at the oil filler and exhaust smoke went away.This oil change has 20 or more hours on it now.I have enough work tomorrow to heat the oil up,think I'll change it,and leave out any additives.

Ratzie..... ....how much does it cost to change yer 6qts of oil and filter? $20 (cheap) What is the cost to rebuild an engine where the crankshaft bearings have been burned from lack of lubrication and you haffta turn the crank???

MMO is NOT lubricant (oil) it is SOLVENT. What is the difference between oil and solvent? Solvent EVAPORATES. What causes solvent to evaporate? HEAT. What does running yer engine do to your oil??? You don't suppose the engine oil heats up, do you??? What do you suppose would happen to all that MMO solvent in HOT engine oil??? Do you suppose it might pressure steam out the oilfiller breathercap??? and even the exhaust???

MMO is good stuff, it just ain't lubricating oil, per se. It dissolves nasty dirty old GUNK. Did you read the instructions??? Drain it NOW!!!..... ...respectfully, Dell

Rick- If your engine was old and neglected like many the MMO probably broke a lot of sludge and other crud loose. I always thought that stuff smelled like diesel fuel.

The only thing I can think of that adding one quart too much would do is allow the oil in the pan to get churned up by the crank shaft and reduce fuel economy... I can not see that it would cause excess smoke out of the tail pipe - but I am not a mechanic by trade.

Too much oil (or oil and snake oil) will overservice your engine and may contribute to blown oil seals, etc.

Your best bet now is to change your oil...and use only oil...and use the correct quantity and hope for the best.

Meanwhile...at risk of starting a revolution with other good folks with opinions as strong as my own....

MMO is nothing more than kerosene, dye, and perfume. (White Laboratories, Dallas, TX analysis) It is a solvent. It does not lubricate. When you pour it into your oil, it washes 5 decades of old sludge loose and sends it throughout your engine, bearings, shafts, and etc. and offers a wonderful opportunity to scratch up surfaces that previously were polished smooth, and damage bearings. Sludge that is cooked in-place, is NOT necessarily a bad thing. It covers nonmoving parts and protects them from rust/corrosion in that high-humidity, warm/moist environment in the crankcase. (The moving parts are not harmed by it because it's stuck to the nonmoving parts, where it belongs....At least it was until you washed it into the oil and circulated it throughout the engine.)

You like MMO in your fuel to lubricate upper cylinders and valve stems? How 'bout a better/cheaper solution? Add the same amount of diesel to your gas and you won't have to pay for the dye and perfume. ;Þ
