Lawnmower + unknow fuel = well, you know

Well, my dad, in his infiinite wisdom decided to leave a gas container with an unknown mix of fuels in the garage, right where our pure 87 octance gasoline usually resides. This of course was not know to me.

Fast foward to yesterday, when I was going to mow the lawn as usual, and proceeded to get the gas to filll the empty tank. I couldn't imediately find the regular container, so I grabbed this other container marked gasoline. I wafted and it smelled like gas, so I filed up the tank. About 10 seconds after I started the lawnmower, it just shutoff, and started again twice only to die within 2 seconds. It eventually remained dead.

Basically, my step dad is really pissed off at me as he somehow thinks that I should have realized that this was a special "weedwacker mixture," even though we do not have a weedwacker, and for as long as I remember, gasoline containers (orange and labled "gasoline") have ALWAYS contined 87 octane gasoline for obvious reasons. Worst of all, I itold him that I would pay for it, and he is still continuously criticizing my logic. Yesterday I went to help paint a condo, and he acted like a real prick the whole time. I ended up leaving after doing have to the condo because I couldn't stand it :(

This is the reason that I cannot find out what the mixture is made of, besides that it is combined for use in weed wackers. As I remember, it had a very light scent of gasoline compared to regular gasoline.


My question is: What might it be composed of, and could it have damaged the lawnmower? If so, what needs to be replaced? Could draining it and filling it with CONFIRMED gasoline serve to rectify the situation?

Engine is a Briggs and Stratton 6.5hp xxCC's






EDIT: It's fixed


Well, I fixed it. What still confounds me is the original liquid I put in there. No one knows what it is and my step dad ain't talking(well, he isn't here, but I suspect he won't want to tell me when he gets home)

I went ot the store and bought some stabilizer and some Carbureator Cleaner. I added the stabilizer to my VERIFIED:D gas can. Then I proceeded to drain the mowever by tipping it and using a funnel and a bucket, as this is appearantly the only way to drain it (no plugs) without dissasembly. I then took out the air filter, sprayed into the carbureator and let it dry. I then put it back together, added gas, primed it, and it wouldn't start:( I finally took out the spark plug and it was well, "icky" to say the least. After attempting to clean it with a new rag, it still wouldn't start, even after 18 "US" pulls ;) :(

I finally got my neighbor and he figured it out only to end up confusing both of us. First, we tried priming the hell out of it, but he kept on saying that he could not smell the gas. Then he showed me how to clean the spark plug with a fine piece of sand paper which helped out a bit. Still, it would turn over once at the most and die, even if he primed it. He then began to prime it while the air filter was off, and "Stuff" seeped out of the opening. According to him, it was water :confused: He checked the contianer of liquid that had originally casued the problem, and told me that it did not smell like a weedwacker mixture at all. In fact he didn't know what it was except that it was heavily diluted. Personally, I had only "wafted" when I had used it, and from a distance, it had smelled pretty normal. After takiing the funnel off however, I couldn't identify it either, except that it smelled sort of like paint thinner.:confused:

Anyways, he primed the hell out of it as I hell it at 45degrees so it would come out. Once it started to smell like gasoline, the lawnmower turned over twice. We continued to prime it after it had turned over and it styaed on. A few more minutes of that and it would stay on for about a minute. I left it running for about 15minutes, ocassionally priming it quickly when it was about to die for the first few minutes, and now it runs really well. Hell, I don't have to prime it at all, even from a cold start ..perhaps due to the stabilizer:D (thanks evadman)

Hell, I just mowed my lawn with the damn thing and did a fantastic job as ususal.


Cost of 2 1/2 gallons of gasoline to fill the gas container: ~$5.00
Cost of fixing the lawnmower: $11.97

My step dad's face when he notices that the lawn has been mowed and that his lawnmover is running better than ever: priceless.
My step dad's face when he realizes that he was wrong and acted like a complete ass: Pircelessx2 :evil:

END GAME
<----WINNER, that is, unless it explodes in the near future or something ;)

Drain the tank and carb, and refill with standard fuel it should be fine. I have done the same before by accident The oil lowers the octane a bit and the engine has a hard time getting hot enough to run properly.

Weedwhackers that run on gas require oil to be mixed in with the gasoline. It's how their engines function and you've probably just effed up your lawn mower. Empty the gas tank and let it dry. I'm not sure just how screwed you are, but I'm sure the oil's going to be a problem for a while.

You could always add a little diesel in the tank to offset the thickness of the oil. ;) :laugh:

That is what I thought. What are they called? For or 2 stroke engines? Basically the lubrication and the combustion is taken care of in the same area, right? Instead of seperately such as in our Lawnmover and in vehicles.

your lawn mower takes straight gas? is it a rider? cause all push mowers i know of take a mix, ours is 50:1

weedwacker mix is typically a 17:1 ratio of gas to oil ours is anyway,

draining it and refilling it with gas might work they also make engin cleaning stuff you can run through it, engine might be fusked also

Use your frickin brain. Would you like instructions on how to move your legs so that you can walk from one place to another?

I used a turkey baster to get it out of the tank and carb.

I have a 5HP push mower that requires straight gas in the gas tank, and oil dumped in elsewhere.

Seriosuly. I am not about to drain it into the sewer. I probably won't try to put it back with the rest of the mixture. I don't know where he disposes used oil, so that is why I am asking.

Don;t call me iuninformed. THat is obvious. Just , please, answer my question.

As has been said, you haven't hurt a thing. Throw the gas in a coffee can with a lid, and use it for cleaning parts or something. After adding the new fuel, choke the carb totally and spin the engine quite a few times. At worst, you might have to dry the plug, and maybe use some starting fluid, but it should run just fine without much effort, and again, nothing's been damaged.

Thanks. I'll try it later....

Your stepfather sounds like a grade-A idiot, exactly the type that shouldn't breed or raise kids. Don't take it personally, my family was the same way and I turned out... um, well pretty fscked up :( But whatever, let his sorry ass mow the lawn.

:laugh: sorry, just being a little playful, that's all. Since neither component is pure (gas mixed with oil), there's no place that will take it off your hand that I know of. There are several car parts places around here like Schucks, Knecks, Napa, and AutoZone -and one of them takes used oil (from home oil changes) and disposes of it for free, but they don't allow it being mixed with any other liquids (like gas which is common).

wtf did you read the thread? goosemaster was the one who put the wrong fuel in, not his step dad.

Shouldn't take that sh1t from your stepdad. He's being a total asshat and..well.. you should kick him in the nads (for personal satisfaction, and so he won't breed for the safety of others)

He was the one doing the family the favor of mowing the lawn, his stepfather was the one who put the wrong gas in the same place as the regular, probably knowing the OP wouldn't realize the difference, and his stepfather has apparently been a complete asshole about the whole thing, unforgiving even with the OP offering to buy a new one. Did you read the thread?

Same. Ours is a B&amp;S 4 stroke engine 6.5 HP. Just remove the old gas and clean it all out. You may need tochange the spark plugs... hth.

True as well. While it is possible to tell the difference, the oil makes the gas a slightly darker color, its not the kind of thing you usually look for. I mean anyone with half a brain would mark weed eater fuel with the mixture ratio.
