Question

In error my son put the weed eaters oil gas mixture in our lawn mower. How will this effect our lawn mower?

Answer 1

It won't run worth a flip, probably foul the plug. Just tip the mower to the side and drain as much gas out as possible and if any is still left it won't be enough to hurt if you refill the tank with fresh gas.

Now would be a good time to mark the two different cans with a distinctive marking. My husband took his soldering iron and marked our can with 32:1 ratio in big letters.

Answer 2

A little smoking. just tip and drain most of the gas mix and refill with fresh. no harm.

Lucky it wasnt the other way around

straight gas would of killed your weed eater!!!!

Answer 3

It will not affect the lawn mower engine. It will help lubricates the overhead valves. There is a very small amount of oil in the weed eater gasoline, oil mix.

Answer 4

Watch the level with usage, and you may have a little more smoke when it is being used.

Answer 5

You can go to your hardware store and purchase a small siphon pump.  Or, a cheaper alternative is using a length of oil/gasoline-rated flexible black tubing.  This will allow you to siphon the majority of the gas from the tank.

You will need to apply suction, either via the handheld siphon pump, or using the tube as a "drinking straw" until liquid flows through.  Liquid flows downhill, as long as the exit of the tube is below the entrance, you will not need to continue applying manual suction.

Once the gas/oil mix is out, fill it up with gas only.  As mentioned, you will likely get a bit more smoke in the exhaust, but if you follow these directions, no permanent damage should be done.

Do yourself a favor and look for the handheld siphon, gasoline isn't that tasty : )

Answer 6

It may foul the spark plug.  The best thing to do is to drain the fuel completely and fill the tank with fresh gas.  The mower my run a little rough for the first tank and you may want to clean or replace the spark plug.  No permanent dammage should have been done to the mower.

Answer 7

to be safe, dump out the gas/oil mixture and replace it with the correct fuel.

Generally, it will just make it smoke more and it might foul the plug, but it shouldn't cause any permanent damage.

It would be more damaging to use just gasoline in a 2 stroke motor.

Answer 8

To begin with, the reason you put oil in the gas for the weed eater is to lubricate the internal parts of an engine that doesn't have an oil resevoir anywhere or a pump to distribute oil throughout the engine.  The oil in the gas is the only lubrication the engine gets.   My old neighbor who ran a small engine repair business across the street from my shop for 30 years, used to say to me, "Son, if you can't see her smoke you ain't got enough oil in the gas."   He never burned  up an engine.  What little oil there is in the gas your son put in the regular lawn mower won't hurt it at all.  As one of the fellows said, it may foul the plug, but that's easily cleaned and reinstalled.  If you drain what you can and replace with fresh gas, it just won't smoke for so long.

Answer 9

Remove all you can and fill with fresh gas. It will smoke like mosquito control trucks. A little oil/gas mixture will burn off but you don't want to burn a whole tank of it.
