BG 44K Fuel System Cleaner 208

BG 44K is the ultimate fuel system cleaner - additive. It’s 11 ounces of high quality detergents and additives that you pour right into the gas tank to restore performance and gas mileage. It removes 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. 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 modern 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.                  

Autobob notes: BG 44K is the strongest product that is still safe to use in your fuel tank. BG 44K is not alcohol based. BG44K reduces or cures fuel deposit issues like; engine surge, stumble, hesitation, loss of power and fuel economy. Also many fuel sender issues are resolved by using 44K. We recommend one can of BG44K every 10,000 miles or once a year. Part # 208

We have a large number of referals and repeat purchases of this product as it is extremely effective. Try it, you will like the results.
Remember to use Redline SI-1 or BG CF5 between BG 44K treatments!

I just wanted you to know that yesterday I put the BG 44K in my Suburban and by the time I drove the 5 miles home when I turned the truck off all was normal. I was so surprised I started and turned it off two more times. It truly is miracle stuff. Thank you again, I just wanted you to know! 



Well, I tried a can in each one of my cars and now I have three new engines. that BG44K is awesome. Man, what a difference in the smoothness of the engine and the renewed power.

I've used BG 44K in all my cars - every oil change - for years and have never had a problem with injectors. Over 500,000 miles with no injector problems and I'm going to keep doing it. I have never had to replace a converter either.

There are certain situations where additives can be helpful. BG Products makes stuff called 44K, which we find to be terrific for cleaning gunk and carbon off of valve trains and out of fuel injectors.

Thank you for your site! BG44K is great, but hard to find. I for sure will shop here again!    



Thanks a bunch Bob, you and Glenn Beck were not lying; this BG 44K stuff was amazing in my BMW 323i with 81,000 miles. It had some stutter and hesitation to it but after a 40-mile round trip the whole motor sounded different, a better sound more crisp sound you might say! All I can say is simply amazing it runs like a top! I want to share with my family and friends, wow!

Thanks so much, Curtis P.


1993 Mercedes 190e with 233,927 miles. A friend told me to try BG44K twice a year. About 3 weeks ago I added it when I filled my gas tank. I always use Shell high test.  I noticed an increase in power almost within the first 15 miles and am now getting 31.3 mpg. BG44K, I still cannot believe the difference. 

Thank You, Judith VB


I just want to say thank you. Ever sense I worked at a dealership I have tried to find a place that I could buy BG 44K. I have seen it do some amazing things on cars that would come through our shop and recommended it to several people while I worked there and even after I left. Now that I have found this website I will be recommending it to everyone. 



My fuel sender gauge would some times work and othertimes show a reading I new was incorrect. I tried the BG 44K after a talk show host recommendation and It Worked! Saved me lots of $ plus the car runs much better now, I am happy! Tommy
