Better Idle. Great for injectors.
BG 44K works! I have a 2016 Subaru STI with 60,000 miles and modifications (go figure) that makes 310 WHP. Not crazy because I'm not trying to blow the block. Lately, I have had some rough idle issues, specifically misfires in cylinder #4. The misfire counts were low with no more than 5 and average of 1 or 2. I put this product in my tank, filled it up with Costco gas, and drove like normal. It has been 1.5 weeks and a half tank since. The misfires at idle are gone. For supporting data, I referenced my Injector Duty Cycle. When the misfires were happening (before adding BG 44K) when idle the injectors operated at 0.96% and after the half tank, they were at 0.90%. Also, the Air-Fuel Ratio is more consistently hitting a 14.7-14.8, before it was 14.9-15.1. The fuel system flows better through the injectors and more efficiently. *Data collected at idle ~750 rpm with no accessory loads.* **I cannot speak accurately about any change in fuel milage as I have not driven far enough to collect that data. And traffic is unpredictable. Although, some of the reviews claim better milage.** Cost: BG 44K is on the high side of fuel treatments on the market. I have used others like STP and never felt like it did anything to truly clean the fuel system. I recommend using it every 30,000 miles. Anymore and it is a waste. Unless you are the kind of person that races to work in ten minutes to not be late, on an empty tank, you will be fine with longer use intervals. But that's another issue entirely. Location: Pacific Northwest. Ethanol in the pump gas can range from 8% to 12%. Not the most ideal but what can you do? Background: I am a technician. No, I am not promoting this product. A dealership I worked for did use BG products and I did notice differences in vehicle performance when conducting services with BG products. Most notable was the gear oil treatment on manual transmissions. The Direct Inject engines take the fuel system cleaners well. If you are having carbon build-up issues check it out. It has been difficult to find a BG dealer where I located and was surprised to see them on Amazon.

Best Fuel Additive
Usually you will hear products being advertised as "Magic in a bottle." As we all know that there is never a magic solution to any of our problems, I can tell you that this is the closest thing to it, fuel additive-wise. I'm the type of person who always keeps up with routine maintenance with all of my vehicles. I get an oil change every 3,000 miles, even if I'm using a synthetic blend. Having said that, I also use a fuel additive every oil change. It may be unnecessary, but it's cheap and it gives me piece of mind. I've never had any major engine/fuel issues, so I'd like to think I'm doing something right. I usually opt for the Lucas fuel additive every oil change that does into the gas tank. From some mechanic friends, this is supposedly a pretty good product. Although I add this every 3,000 miles, I've never really been able to tell a difference performance-wise. The same goes to the other fuel additives I've used in the past. I tried B&G's 44k for the first time, a while back based on a recommendation from a local shop. I've never heard of it before and I thought it was quite expensive for a fuel additive (approx. $20 vs. your standard $3-$5 bucks). I decided to research the product when I got home and I found that it had great reviews. I decided to give 44k a shot. As expensive as it is for a fuel additive, it's still a small investment. I'm glad that I did. This has been the only fuel additive where I actually noticed a difference in performance. Nothing significant (again, there is no such thing as "Magic in a bottle"), but I definitely could tell it was working. I had an increase in MPG and I could feel a little more HP when accelerating. Now, I won't be using this every oil change as it's only recommended once or twice a year. So I'll be using this every 3rd oil change and continue to use the Lucas in between. FYI - I currently drive a 2001 Jeep Cherokee (XJ)

Used this on my 2011 Audi A6 3.0T with 100,000km (62k miles). I knew something was up with the fuel injectors because I was having surges in acceleration after letting off the throttle at higher RPMs and was going through much more gas than usual (although I never got a check engine light). I assumed that I would have to do a carbon cleaning and change the injectors. Before spending the money on that I decided to try a fuel system cleaner and saw this one was highly recommended by Audi owners. I went to the gas station, poured this into my gas tank, and then filled the car with gas. Pretty much instantly my car has stopped surging and has restored gas mileage. To my surprise the throttle response feels much better and the idle has lost its shakiness. Very happy with the outcome of something so simple. Definitely recommend for anyone with an Audi that is getting up there in mileage.

I searched lots of petrol treatments to treat my engine and kept coming back to this one. I have recently used it in a Mini Cooper S 2014 which was suffering with a rough idle at cold and some hesitation on acceleration low down in the revs. I used a full can of the treatment in a full tank of fuel, put the contents of the can in your tank before you add fuel to mix it. I am half a tank through the treatment so far and have noticed a difference. Smoother idle on start up, tighter and quieter engine when idling and noticeable increase in acceleration. I am still working the treatment through my engine but so far I am very impressed indeed. This company also do oil treatments (flushes) etc so I may well go down that line as well to give my car some real TLC. I will buy the BG 44K again on my next second hand car as a matter of course I think.
