Ratings & Reviews for Mechanic In A Bottle 8-oz 2-cycle or 4-cycle engines Fuel Additive

Worked as advertised.

My power washer wouldn’t start after sitting over the winter. I emptied my gas tank and poured half of the bottle into the tank, pulled the handle and it started right up. Great product. Worked as advertised.

Didn't work for me.

Followed the instructions. It wouldn't bring my carburetor back to life.

N/A

Worked great! My lawnmower wouldn't start after sittiing all winter... So I added an ounce or two of this stuff to the little bit of gas left in the tank, pulled it a few times and it still wouldn't start. I then let it sit for about 20 minutes (like the directions say), dumped out the gas mixture in the tank, added fresh gasoline, pulled the starter cord and it started like a champ... Just like it was brand new (and this mower is 17 years old).

This stuff works!

After gas sitting in the tank all winter, mower did not want to start. Added a bottle and it ran much better.

Impressed

I was told about this thru word of mouth. My brother's boss had taken his side by side to the shop. They told him instead of rebuilding the carburetor they just used this. He was very impressed at the performance after this being added to the fuel. I've used it and will continue to use in my gas operated equipment.

Two for two

This additive has kept me from having to tear down and clean two different carburetors on engines that were running poorly from having gasoline left in them for an extended time. In both cases I poured a generous amount of the additive into the tank with the questionable gas and moved engine around to mix thoroughly. Cranked engine up and let it run stumbling for a few minutes then shut down. Repeated the short crank up/run times over the next few days. Engine runs smoother with every run. ...

It works! But instructions missing a step

I have a Craftsman/MTD snow blower that is only 2-3 years old. This year after adding gas it refused to start. Initially I add Mechanic in a Bottle to the existing gas. Didn't work. I then drained the fuel system, added 4 oz of Mechanic in a Bottle and let it sit overnight. Following the instructions I added gas to the tank and tried starting....still didn't start. HERE IS WHERE THE INSTRUCTIONS ARE MISSING A STEP.... I then unscrewed the carburetor drain screw and let the Mechanic in a Bo...

Mechanic in a Bottle

Works so incredibly well I bought and gave a bottle to a mechanic friend. Said after a few quick pulls of recoil rope a chainsaw he thought needed a new carb was running perfectly well again.

Wonderful!

This product worked wonders for my Troy-bilt TB30-R Hydro lawn mower. I had bad gas in it before, and this with 10% ethanol from Exxon fixed the job! It’s running like new again!

Worked very well.

A Troybilt 2 stage snowblower would start but die after a few seconds when the prime was consumed. Obvious that fuel was not getting to the carburetor as I forgot to run engine dry after last winter. I put in some fresh gas and mixed in two ounces of Mechanic in a Bottle. I let the snowblower sit for ten minutes. I primed and started it, and it died again after about five seconds. On about the fourth start it stayed running on full choke. I let it keep running and after a few minutes I was able ...
