BG 44K Fuel System Cleaner

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!

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.

Amazing product. I felt a big difference in response and torque after 5 minutes of driving! Plus the car was running smoother the more I drove. Recommended to all my friends.

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
