44K Fuel System Cleaner

HOLY!! Ok so I never write reviews ever! But this product saved me what was going to be nearly 1k in repairs. For a week my car was having a hard time starting, crazy rough idling, the most sluggish acceleration, it even stalled on me twice at a red light 😭 also the check engine light came on, and me being a young girl who knows nothing about cars, it was hard to not only know what to do but also to find a mechanic I could trust. 3 separate shops told me I needed my fuel pump replaced along with my ignition coils, but I decided to do a little bit of research into these symptoms which led to fuel injector cleaners. I started with Lucas oil , which literally did nothing for me, but THEN, I came across this bottle. It took 3 days to arrive but as soon as I got it, I drove to the gas station added it to a full tank of gas , and I kid you not, I noticed the difference it had made before even diving out of the gas station! Every symptom I listed has vanished and my engine light has turned off! I forgot how much power my car had before this. It now drives soo smooth and so much stronger. I’m so glad I took a chance on this!!

I used BG 44K Fuel System Cleaner after performing a valve cleaning with CRC GDI IVD Intake Valve & Turbo Cleaner, and I’m thoroughly impressed with the results!Here’s why BG 44K is worth it:Immediate Improvement: Right after adding BG 44K to my tank, I noticed smoother idling and a more responsive throttle. My engine felt like it was running much cleaner, almost like it had been rejuvenated.Enhanced Engine Performance: There was a noticeable improvement in power delivery, especially in the mid-range. Acceleration felt smoother, with no hesitation, which I didn’t have before.Effective Cleaning: BG 44K does an excellent job of cleaning the fuel injectors and combustion chambers, helping eliminate carbon buildup that may affect fuel efficiency and engine performance.Fuel Economy Boost: I noticed a slight improvement in fuel economy, which is always a nice bonus after such treatments.While CRC did a solid job with the valve cleaning, BG 44K took things further by cleaning the fuel system and combustion chambers, making the engine run even smoother. It’s clear that this product is formulated to improve long-term engine performance.Bottom Line: BG 44K is a must-have if you want to keep your fuel system and engine running at peak performance. I highly recommend it, and I’ll definitely be using it as part of my regular maintenance routine.

I was skeptical at first because of the price, but BG 44K Fuel System Cleaner completely blew me away. After using it in my 2015 Honda Accord with around 90k miles, the results were almost immediate. The engine started running smoother, acceleration felt more responsive, and even my fuel economy improved slightly—about 1-2 mpg better than before.What I really appreciate is how easy it is to use. Just pour it into a nearly empty gas tank and fill up with fuel. That’s it! No special tools or mechanical skills needed. I used it right before a road trip and could feel the difference on the highway—no hesitation, cleaner idling, and just a better overall driving experience.I’ve used other fuel system cleaners in the past, but nothing has made a difference like this one. It’s no wonder a lot of professional mechanics and dealerships recommend it.✅ Pros:Noticeable improvement in engine performanceSmoother acceleration and idleSlight boost in fuel economyEasy to use—just pour and goTrusted by pros (and now by me!)⚠️ Cons:A little more expensive than other cleaners, but you get what you pay forFinal Thoughts:If your car feels sluggish, or if you just want to keep your engine running at its best, BG 44K is totally worth trying. I’ll be using it every 10,000 miles from now on. Highly recommend!

Great product, does exactly what is says it will do. 18 F150 5.0L

I've used several different kinds and this seems to be best. I have a 2018 kia and was recommended by kia only thing is my engine light came on after about 3 days and none of the others ever did that. But after about 5 days and trying to run that gas out at about half a tank the light went off and has stayed off so far but there is an increase in power absolutely

I got this for a 2004 Subaru Outback which works best with highest octane and Fuel Treatment 4 times a year for my vehicle. I got this to clear things up more clearly and it did the trick. 1st time virgin user of this product for this vehicle and she's happy now

This stuff works really well. I was having miss fire issues with my jeep which ended up being the coil packs and crankshaft position sensor, but this stuff gave life to my jeep again. I’ll buy again for sure!

I used this on my 2020 RAV4 hybrid with over 50,000 miles on it. Used about 70% of it in one full tank and the rest of it I dumped in another full tank, as per how much should be used. Upon my reading online after having a hard time trying to find the official Toyota fuel system cleaner which the manual recommends using, I discovered that this is the product that Toyota puts in their own bottle.Because I used this when the weather got severely colder, I can't exactly say how much my mileage immediately approved. Because of where I live, gas is different in the winter (google "winter gas") plus I'm using the heat, which makes the engine run more in the hybrid. What I can say is year over year for the same season, I'm getting 5 to 10 miles more to the gallon. Even after I first bought the vehicle as soon as winter hit I went from 36 miles to the gallon down to 28. Now I'm at 32 minimum and that's if I'm really heavy on the pedal. If I actually drive economically I'm getting 38 easily. And this is in the winter. I can't wait to see what mileage I get in the summer.Also the engine is quieter and a lot smoother when it's idling. I wasn't expecting that.I hope they never change the formula.
