Product Details

Fix poor or non-running engines. Rejuvenates the fuel system for efficient starting and operation. Cleans varnish in the fuel system without having to remove the carburettor.

Mechanic In A Bottle is suitable for both 2 & 4-Stroke engines. It is designed to combat and help fix fuel related issues on poor or non-running engines. It is also recommended to be run in machinery during its first use after being stored for an extended period. (Use poor running dosage).

• Cleanses your equipment’s fuel system so that it starts efficiently and operates in top condition
• Removes all varnish in the fuel system without having to remove the carburettor
• Replaces lost Octane and rejuvenates old fuel
• Revitalises rubber and plastic components

Poor Running engines: Pour 8ml (2 capfuls) per 1 litre of fuel into the fuel tank. Start the engine and run for at least 15 minutes. It starts working in as little as 15 minutes. Performance improves over time. Do not drain the fuel tank.

Non-running engines: Drain the fuel completely. For small power equipment, (e.g. Brush Cutters, Chainsaws, etc.), add 60ml into the empty fuel tank. For larger equipment (e.g. Lawn Tractors), add 120ml. Work the MIB into the carburettor using the primer bulb or starter mechanism. It starts working in as little as 15 minutes. For the best results, let the engine sit for at least 4 hours before restarting. Do not drain the MIB from the tank, add fresh fuel and follow the starting instructions. With severely contaminated fuel systems, let the MIB stand in the system overnight. Repeat as necessary.

Rated 5 out of 5 by from Literally does what it says on the bottle So I have been restoring a 30 yr old Kawasaki sports bike over lockdown. It's been running well, but last 2 weeks were problematic, and it looked like some fuel had gummed up the carburettors, as it was running extremely roughly through the mid range where tlthey come off the idle jets and start to use the main jets in the carbs. Knowing getting the carbs out of this bike (1989 Kawasaki GPX750) would be a massive pita(!), I found this stuff online. Finding it at Toolstation for 8ish quid, I thought I'd give it a go. Wow. One shot of 45ml in the half full tank, and ran it the next day. 20 mins on the drive, mainly idling, the odd rev to help it warm up. It suddenly started running perfectly again. Day later, ride it to work, then rode it to some committee meetings in my local area. Hasn't missed a beat. I definitely recommend this stuff, it is brilliant for the price. Just look after it carefully as sounds massively toxic from the label!!!

Rated 5 out of 5 by from Yamaha Xj600 fixed Bought this before deciding whether to send my motorbike off for a strip and carb clean as it was running boggy 3000-5000 revs. Followed the instructions.Left it overnight after running it for a cpl of mins. Rode bike for 40 miles and it was still a bit lumpy. I hit the motorway and at 60mph it suddenly coughed, spluttered then whooosh ,a sudden speed increase. Has run like a dream since with no issues.

Rated 3 out of 5 by from Does It Work? Read On... Tried this in mower which kept dying after a few seconds - presumed carburettor gummed up after winter storage, and couldn't see how to get it off to clean it. Emptied fuel, poured half a bottle into tank, and left over night with fuel tap on; next day, it initially ran longer before dying again, but after a few tries, mower ran more or less normally and I cut the grass. Was this due to Mechanic In A Bottle? Who knows! It could have dissolved deposits blocking carb. or my constant attempts to start the mower, including tipping it and shaking it in all directions, could have dislodged the blockage. Would it have started and run ok eventually without Mechanic In A Bottle - again, who knows. So I can't give the product more than three stars, as I cannot prove whether it worked or not. But it is a fuel additive, it should help when using standard unleaded fuel, it can't do any harm, and it is a lot cheaper than taking the mower to a repair shop!
