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.

B3C Mechanic In A Bottle 118ml is rated 4.6 out of 5 by 40.
Rated 5 out of 5 by from Great product I made the rookie error of leaving fuel in my 2 stroke hedge trimmer over winter with the expected result that it wouldn’t run properly when I came to use it in the spring, although it would start and idle it would cut out as soon as any load was put through it. My local garden machine repair shop told me that they couldn’t get parts for my trimmer so repair wasn’t an option. I looked for carb cleaner and this product came up with good reviews so thought I’d give it a whirl. I followed the instructions for engine not starting even though it was, left it over night, started it the next morning and let it idle for 20 mins and after that it was running good as new. Well chuffed. And valuable lesson learnt

Rated 5 out of 5 by from This stuff is magical This stuff is absolutely fantastic, as a long retired mechanic I was very sceptical about using it. I have a motorcycle that has been stood since last July, drained the tank and carbs added this magical liquid to the tank and fresh fuel. She coughed and spluttered and away it went. Absolutely amazing.

Rated 5 out of 5 by from Worked for me Really impressed with how well this worked. My motorbike has been sat for several years, and when it last run it was misfiring and stalling. Followed the instructions on the bottle, fired it up, and within 15 mins, it was running spot on. Highly recommended.

Rated 5 out of 5 by from Seems to do what it is intended to do This product does help with clearing carb jets if used for some time in the fuel.
