Would RecommendOnce I put this in my lawnmowers gas tank it sounded more powerful and ran better especially when using the propeller feature.

It cleans buildup out of carburetors quickly.
Would RecommendAfter having to use starting fluid to start my riding mower, I decided to try the mechanic in a bottle. After using the tank of gasoline I treated with the product the mower began starting without starting fluid and without a lot of cranking.

Great Product. If you have a 2 or 4 stroke engine of any kind pour a few ounces into the gas tank at the beginning of the season. It neutralizes anything in fuel line or gas tank that shouldn’t be there.

Always start with fresh fuel.
Would RecommendWorks as advertised. Best small engine additive invented. Repairs minor carb problems, old fuel issues, dissolves varnish deposits & blockages, frees sticky float parts, AMAZING product. Small engine stored with fuel for a year, dumped fuel and added fresh fuel with product MIAB as stated in directions, let it soak for some time, started engine and ran 1/2 tank gas out and this product improved the performance of the engine.

Well, I tried, it didn’t
I was very anxious to try this as I’d heard that it worked miracles in engines that have sat for a year without working. Didn’t work. I next tried this on my riding lawnmower that would suddenly die on me and needed more gas after letting it set for two days I didn’t see any improvement. I don’t think I will try this again.
