Description
Review this item in the context of the repair, installation access, nearby parts, and the result the completed job is intended to achieve.
BG 44K is the ultimate tank-treatment fuel system cleaner. Itâ€s 11 ounces of high quality detergents and additives that you pour right into the gas tank to restore performance and gas mileage. It vanquishes deposits in combustion chambers, intake manifolds, ports and on valves and restores flow in fuel injectors. Basically, it cleans the entire fuel system! Gasoline quality is inconsistent. And when gas at the pump is poor quality, it can cause deposit buildup, inefficient ignition and combustion and poor power output. To make matters worse, small, high output engines are extremely sensitive to deposits that build up on fuel injectors, intake ports, on intake valves and in combustion chambers. Even small amounts of deposits cause increased exhaust emissions, reduced fuel economy, drivability problems and engine knock. BG 44K is formulated to safely and rapidly clean the entire fuel system, including fuel injectors, intake valves, ports, fuel filters and combustion chambers. Because it provides efficient removal of upper engine deposits, BG 44K reduces problems caused by deposit buildup such as engine surge, stalling, stumble, hesitation and power loss. BG 44K technology has been proven to increase combustion quality and power output. BG 44K will provide quick cleanup of coked fuel injectors and corrosive deposits on the Fuel Sending Unit. It is compatible with all fuel system materials, alcohol-blended fuels and common fuel additives.

Worked out wonderfully to clean out my fuel system and fuel injector. I drive a 20 year old Nissan Altima. When she was not running right I prayed that it was not something majorly wrong with the car. I have been keeping the car well maintained,but ,being 20 anything can happen. Added the product and a full tank of regular gas(no ethylnol). It took about three long rides to work. But there are no more issues. My car runs great again. I would highly recommend this product if you have fuel system issues. Thanks so much.

I have a 1989 Dodge Dakota that I drive less than 100 miles per month. The ethanol gas absorbs water from the empty space in the gas tank and water causes injector corrosion, rough idle and slower acceleration during driving. After 1 bottle and driving once a week on the freeway it took about 4 weeks to clean the injectors. Now the idle is smooth and acceleration is improved. I also used BG fuel dryer to remove the water from the gas. I use BG44K Fuel System Cleaner every 3 months and BG fuel dryer and BG ethanol defender every 2 months because my truck is parked for a week or more per month. Your everyday car/truck with regular gas full-ups can use the recommended mileage maintenance per BG. I recommend these products.

This stuff is amazing. I had a clogged fuel injector that was causing a misfire code in the #1 cylinder. My 2003 Montero Sport 6 Cyl engine would spit, sputter, hesitate and was down to 12 mpg when it should have been 20. After 1/4 of a tank, the engine began to run smooth and it has more power then it has had in years!! BG 44K saves me a lot of money since the mechanic wanted to replace the fuel injectors. I highly recommend this stuff if you have fuel system build up or to prevent it. I’ll be using it every 6 months from now on.

I am very very sceptical of additives. But this was written up, and so many people said it worked. I have a 1999 Toyota 4 Runner. V6. I am the original owner. The SUV never got good mileage. Max was 20 or 21 when it was new, on the highway. It was getting about 15 tops… For years….it was doing very badly. After one treatment, it was back to 19! After two treatments it was at 21. It is right off the diagnostic and verified two ways. After that, it has been staying at 21 now for several tanks for highway driving. Not great for a modern car, but this is as good as it gets for this one. I can confidently say it restored my MPG on this. Anyone with an old trusty car, highly recommended.

I have a 2005 Subaru STI. I had good gas mileage on my old Motor that a friend blew. I was getting close to 300 miles off a full tank. I know these cars use a lot of gas but the new motor I was getting less than 150 miles off a full tank. Since I have no check engine lights on so a mechanic recommended this product to me, he said do it at least 3 times. On the first try I immediately seen results. I highly recommend if u are having issues give this a shot before wasting money on diagnostics. I can’t wait to see the true result after the 3rd try!

I’ve used 44K off and on for years. I swear I heard my car purr yesterday. This product works for any car, make or model. It can save you hundreds of dollars on car repairs.

I love BG44 products, they are a bit more than other brands, but work it. Better MPG noticed.
