BG 44K 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!

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.

I put the stuff in my aunt's 50-year-old lawn mower. Now it's running like a brand new machine.It was previously running bad and I didn't know how to fix it and she couldn't afford a new lawn mower. I was really surprised how well this stuff worked. Maybe now that old mower last a little longer

My 2003 C5 Corvette was making a rattle and click noise. I figute it must be the fuel injectors. After applying 44k the noise went away and did notice better performance and mpg. Highly recommended, will buy again!

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 great for when you first buy a car and you don’t know how well it was maintained. This is a really strong cleaner that isn’t really needed very often in your cars. I think the price reflects that. If you’re wanting to go with something you can put in your fuel system on an interval, go with something like Seafoam. If you just bought a car that has a really dirty fuel system or you don’t know how bad it is, run this through it.

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.

This bottle, works magic, I poured it in about a quarter left on the gas tank, almost to empty and then filled my ridgeline up, drove for about an hour and i noticed the difference immediately, stuff works great, put one in yearly, your car will love you for it, or if you have money 2-3 times a year will do.
