BG 44K Fuel System Cleaner Enhancer 11 Oz (Pack of 2)

my coworker about bg 44k as my corolla is having some fuel mileage issue, and this is exactly what the dealership is using but at a friction of cost! its very easy to use, just pop the can open, and pour it in tank, fill out, and you will see performance and improvement on your mileage right away!

Simply add it to your fuel tank and fill the tank to the top, if you do this when your car is not being used for a couple of days, it will give the product time to clean the inner surfaces of the tank, letting it sit at least overnight will be better than pouring it in and driving straight away.

Great product helps keep my vehicle going strong.

Just like most folks I can be pretty skeptical about any additive that over promises and under delivers to that promise. WELL, you need to try BG 44k! I am a fan of BG products and have used a multitude of them from my early days driving around in my VW rabbit. I now own a 2019 Tundra 5.7 with 50k miles and was noticing that the idle was not all that smooth as it was at 20k. So reading through the forums, this product was recommended by a number of folks. Since I am not picky about the gas I put in my truck, I am sure that the lower quality generic brands of gas I use is not all the cleanest, leading to some build up in the motor. After adding this to my tank that was half full (~18 gallons) I took a long road trip where I ran it down to just about empty (low fuel light lit) and then refilled the tank with some normal 87 octane gas. All I can say it that after that run, my truck runs better than it did at 20k. No more sluggish acceleration (better throttle response), the idle is super smooth now and I actually gained a 1mph increase in fuel economy. I know folks will call BS on the fuel economy increase, but I swear it happened, as I have a lead foot and know how much of a gas hog the Tundra is... This was witnessed by making the run from PA to MA on one tank, over 400 miles, which is the max range of the truck and still had plenty of gas left over before the low fuel lite would be coming on. Yeah it is a bit expensive for what it is, but I like the results of what I got from using it in my truck.

I tried Techron in a 2009 Toyota Sienna LE and this one for a 2011 Subaru Outback 3.6R. Using BG 44k generates a noticeable gas efficiency improvement, but does not see the same improvement by using Techron.
