Rated 4.0 out of 5.0 by Bring the life back to your gas powered equipment Needed an additive to help get my saws and lawn maintenance equipment running their best. Added a little to the fuel and ran each piece of equipment for 5-10 minutes. I started to notice smoother running, better throttle response and easier starts. This is not a cure-all product or a way to repair mechanical damages to small engines. Further adjustments to my equipment may still be necessary to ensure the best operation possible. I’m using this additive in all my ongoing fuel mixes. November 13, 2012
Rated 5.0 out of 5.0 by Saved my Snow Blower I purchased this in desperation. My 23 year old Snapper 2-stroke Snow Blower (old reliable), stopped running during a snow storm and wouldn't start again. We were getting another storm 3 days later. After looking online and thinking about buying another blower, I decided to try this out from all the great reviews on a forum. All I can say is, I'm AMAZED!! I put 1oz in the blowers tank let it sit for 15 minutes turned it to full choke, primed it and tried to start it. It took 2 pulls to start it, but for 5 minutes I had to keep pumping the primer a couple of times about every 30 seconds. After those 5 minutes it ran on its own. After 10 more minutes I turned the choke off and it was running like it was new! I couldn't believe it! This stuff is definitely worth the $7!! February 26, 2015
Rated 5.0 out of 5.0 by Good with lawnmower Used MIB in my lawnmower before it was hesitating but now I have no problems what so ever. November 20, 2015
Rated 5.0 out of 5.0 by BUDGET SAVER We have had the most trouble out of our mower. It eventually wouldn't start. We went to home depot to purchase another one from our emergency budget. I saw this sitting on the shelf and asked my husband if he thought we should try it before spending so much money on a mower we just purchased 2 seasons ago. Our 5th mower in 11 years. The mower would not start or would and then quit. My husband put mechanic in a bottle in and the mower immediately started. It restarted, which it wasn't doing, easily. This stuff saved me $250 THANK YOU for making it and Home depot for Selling it. September 21, 2014
Rated 5.0 out of 5.0 by An absolute life saver! For the first time in 12 years I accidentally left last years gas in my snow blower. So of course this year it reminded me of my error by not starting. Being the You Tube mechanic that I am, I began my diagnosis with Google. Everything told me I had a clogged or dirty carburetor. The 11 minute You Tube video made it look very simple to disassemble and repair. Four and half hours later I felt like I had it apart, cleaned, and reassembled. Moment of truth, it started and ran. Unfortunately, it ran like the first car I bought when I was 16. Frustrated and annoyed, I read about this product. After seeing nothing but positive reviews, I gave it a shot. To my amazement, Mechanic in a Bottle, was INCREDIBLE!!! I poured 1 ounce into the full gas tank and let it run for 15 minutes. It ran rough in the beginning, but began to run smoother. After about 10 minutes it was purring like a kitten. I am absolutely stunned by this product and am certainly a believer. Not to mention, it makes me look like a superstar to the wife, who wanted to drop it off at the repair shop early on. A must for anyone with small engines! January 10, 2015
Rated 5.0 out of 5.0 by Wonderful stuff!! My Honda mower was stalling out, cleaned the spark plugs and it still stalled out. I pulled the plug our and it had a lot of soot and carbon on it. I put a new plug in and it ran for about 8 minutes and was about to stall out again. I poured in half a bottle of the additive in the tank and let it run a few minutes. Started mowing and the performance was markedly improved. The more I mowed the better it got. I even had to check to make sure the idle wasn't set too high because it was running so well. First time I've ever had an additive that worked like advertised. August 14, 2014
Rated 5.0 out of 5.0 by MIRACLE!! Awesome product! Our snow blower wouldn't start even after replacing spark plug, changing oil, etc... It was only 1 year old. We thought we would have to trash it and buy a new one then I did some research online and read about this product. We bought it, followed the instructions and the next day, the snow blower started right up!! We were so impressed we want everyone to know! January 18, 2015
Rated 5.0 out of 5.0 by Does what it says Was having trouble with my snow blower starting and running, once I got it started it would idle really rough and was stalling quite a bit. Decided to try this after reading reviews online. It worked wonders! I put it in an empty tank and let it sit over night, the next day the engine started right away and ran great. Didn't stall once the next time I used it. I will be using this every year now to keep things running smooth. November 23, 2014
