44K Fuel System Cleaner

I was recommended this product because I had my caddy diagnosed with excessive carbon buildup & my check engine light was on. I was told to do 2 tankfuls & then have the oil changed because this is a very aggressive cleaner. My caddy is a 2007 with 205,000 miles. Not only is the light still off - but mileage improved by at least 3 MPG. I got a 35.4 reading which is a new high. Throttle response is notably more responsive - great increase in performance

I decided to try BG 44K Fuel System Cleaner after hearing good things about it, and I’m glad I did. It’s simple to use. You just add it to the fuel tank before filling up, and that’s it. After running through a tank of gas, I did notice smoother idling and slightly better throttle response. The engine felt more responsive, especially during acceleration. It’s not a dramatic overnight transformation, but there was a clear difference in how steady the car felt at stops. It also gave me peace of mind knowing it’s designed to clean injectors and the fuel system more thoroughly than basic additives. I’ve used cheaper cleaners before, but this one feels like a more professional grade product. Overall, BG 44K is a solid fuel system cleaner that seems to do what it claims. If you’re looking to help maintain performance or smooth out rough idling, it’s worth trying.

We bought this for my daughter's 1998 Jeep Wrangler. The jeep is in great condition with only 67,000 miles. For some reason it had a slight lag when cold starting. We had it checked out by our mechanic and found everything was working as it should. He recommended we try BG 44K Fuel System Cleaner and he swore by its results. We tried it and found it resolved the lag when cold starting. The Jeep drives smoother and its getting slightly better gas mileage. I plan to use this stuff a couple times a year. Well worth the money! It arrived completely sealed and was very simple to pour into the gas tank.

I've used this a couple times, it has shown to improve gas mileage and keeps my cylinders running smoothly. I used this product now twice, works better then other brands I have used in the past

Best product ever, it saves you fuel and clean the inlet walves properly.

Excellent Product it works Great

We have used this a few times on various vehicle, the last one was a 2003 Ford F150 which as missing a bit and running rough. After replacing the plug at 107,000 (were also replaced years back at 75,000). Anyway, a tank with the BG 44, followed by a tank with SeaFoam, has cleared it up and it runs like is new, smooth start, clean quiet idle and runs smooth down the road.

always use this in my 2010 VW CC every 6 months approx. Seems to keep it running cleaner although I will say different car dealerships have varying positions on whether it should be used or not. I use it--my car is not new. I hope it has been a good thing for its maintenance and longevity.
