BG44K Fuel System Cleaner

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

Here's my experience from using this for the better part of 10 years.I've used this in the following vehicles with the following engines and the following mileage:2007 Toyota Tacoma 4.0l 1GR-FE V6 97,500 miles1998 Honda Civic DX 1.6l D16Y7 I4 178,000 miles2014 Lexus IS250 F-Sport 2.5l 4GR-FSE V6 87,000 miles2009 Kawasaki ZX-6R 0.6l I4 9,800 miles2014 KTM RC-8R 1.2L V-Twin 7,300 milesThis product does exactly what it states it will do. It will brute-force clean a complete fuel-injection system tank to injector. Nothing else I've tried generates such drastic changes at such a rapid pace. With that being said, there are two caveats that should be noted with this:1. This product should not be used with any carburetor in any capacity, whether that be in a power equipment role (chainsaw, lawnmower, generator) or an older vehicle that utilizes a carburetor and associated manifold. This product is incredibly aggressive and will chemically attack any soft rubber that's not designed to deal with modern ethanol-based fuels.2. I do not recommend running this more than once every two years unless the local fuel quality is so severe that it necessitates more frequent use. This product really needs some relatively significant varnish and/or contaminant buildup to have something to target.With that being said, I've never had any issues with catalytic converter or oxygen sensor error codes when using once every two years.So... Do I recommend this? Absolutely. No question about it. So long as it's used bi-annually, it's perfect.

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.

Previously had used BG products on high mileage GMC truck with good results recently learned GM is now recommended this additive for use in their vehicles at each oil change to improve mpg and performance plus addressing oil blow by in induction system - it appears GM may now bottling this product also under their label too?

This is a great product, and you should follow up with the ethanol combo.

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.

Expensive but worth it. It instantly improved my fuel economy!!!
