BG 44K Fuel System Cleaner

It is more expensive than most, but if you have to keep repeating the use of the other cheaper one than this maybe cheaper than the less expensive ones. I will see the out come in my 2016 CRV which is were I used them repeat, but in my 2018 Lexus 300H it was a one and done.

Can tell a difference in your car's performance only if you don't use the most expensive gasoline. I use regular and can really notice a difference

This is the product/brand that came highly recommended by my mechanic for yearly car maintenance. I don't drive my car very much and it sits a lot so one of these once a year keeps it running good.

just add it to your tank when it's nearly empty as you're getting ready to fill up your tank with new gas. then drive that mixed up gas to empty before refilling again. pretty easy to use.

BG 44K FUEL SYSTEM CLEANER helped improve my van's engine. I was having trouble with the engine power surging until it eventually stopped. Took it to my mechanic and he replaced the alternator. However, after the replacement I still had the problem with the power surge and remembered that a man recommended me a fuel injection cleaner that he uses even on new vehicles with no problem. And it helps him to save money on gas for the life of the vehicle. So I bought this BG 44K FUEL SYSTEM CLEANER, followed the instructions and right away I noticed a difference. You are supposed to fill tank half way with gas then pour fuel injector, then fill the rest of the tank with gas. Then you should drive it on long distance or have it running at least all day. But I just wanted to drive around a little bit. So on day one, power surge happened at least two to four times. Day two, power surge happened at least two times. Day three, once, power surge happened. Everyday my vehicle is getting better and better. And I have yet to drive it any further but I feel the performance getting better and better the more I drive it. I recommend this product. Add it to your tank at least twice a year. The beginning and towards the middle of the year if you have an older vehicle and still maintain it. My van is 2011 year

Bought this for a friend with an older Toyota Corolla with 100k miles on it. She said it improved engine pickup and vehicle was not so sluggish anymore. Recommend this product.

My father always recommended using BG on our vehicles, and I have to say that not one product I've purchased from them has been a disappointment. I've used much of their products except the EPR , which I've been meaning to try sometime soon. But this 44K Fuel System Cleaner made a noticeable change. After pouring it into a full tank, I drove it on the freeway for about 20 minutes and then parked it. The next day, when I jumped in the car, I honestly spaced and forgot that I added the fuel system cleaner in it the previous day (plus I've never used a cleaner that made a difference after only 20 minutes of higher speed) so I wasn't expecting anything. But I noticed right after I turned the key and felt the starter and the engine turnover, it was smooth and less vibrations. Mind you, I also never even noticed I had a somewhat rough starting motor, but now, ever since I added the BG 44K, every time I start it, she turns over smoother and has less vibrations as she idles. I can't wait to see what else is improves, like maybe a little better gas mileage. Nevertheless, I am very impressed with this cleaner. After only just 20 minutes of higher speed driving, it made noticeable improvements to my engine. So I highly recommend this product in most gas-powered engines, especially if you have a GDI engine like I do. They are designed to be more efficient, but with that design, carbon builds up much more because fuel isn't touching the intake valves like they normally would, so instead, carbon deposits build up. I'm just trying to find what's best, that will extend the lives and efficiency of my motor engines. This is definitely the best fuel system cleaner that I have ever used, and I highly recommend it!

To expensive in comparison to all the others.

after having Bg intake cleaner performed. poured a bottle of Bg fuel cleaner into the tank and could feel the acceleration.

It didnt help my issue at all.
