BG 44K Fuel System Cleaner

Best stuff. My old local racing specializing auto garage used and recommended BG products. New town, the (big) local dealership really likes using BG products too. Even the 'advisor' or whatever they are highly recommends them, especially the 44k, talking it up the last time I was in there. Recommended using it after each oil change, or as often as oil changes anyway. I use it in concert with Ethanol Shield to TRULY absorb and burn off water in fuel system, then the 44K to clean any results of that. Have solved rough running issues that couldn't be figured out that way!

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

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

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.

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

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.

Excellent Product it works Great

Very good

Great results for my Volkswagen Passat 2020: no misfires, no engine shaking, very good fuel consumption, and the engine runs smoothly.”

شف الفائدة من اول استخدام بصراحة ما توقعت ان مفعوله قوي استخدمته على تاهو ٢٠١١ وراحت التعليقه اللي فالدعسه بعد فتره بسيطه

ماكنت اتوقع هذه النتيجة ،، رانج ايفوك 2020 كانت بيها صرقعة بالمحرك وتاخر باستجابة دواسة البترول وثقل بالسيارة ،، كل المشاكل انحلت بعد ما استعملت المنتج ،، واغناني عن الذهاب لورش التصليح ، انصح به وبشدة

My car was having trouble starting in the mornings, most likely due to the carbon buildup around my spark plugs and in my engine. Used a bottle of this on a 3 hour road trip on the highway and the car has no issues starting now. Great product.
