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.

UPDATE April 22 2017 :my good mechanic buddy suggested I should use this product on ...
Previous experience: During one of my regular visit for brake change and oil change with a "Chain Service organization" which starts with letter M, my good mechanic buddy suggested, I should use this product on my wife Toyota Camry 2004 with currently 222K miles, this was 2 years back, at that time worked perfectly, recently the same car was running rough, and he asked me when was the last time you had changed you spark plugs, I said "I do not remember" ( I am do not even remember if spark plugs were ever changed on this car, I just keep it oiled and serviced.), this triggered a thought , why not use the same product he recommended 2 years back, so I went ahead and ordered BG 44K Fuel System Cleaner (2 cans), and received it two days back, and put one Can in my wife car (Toyota Camry LE 2004), when the gas tank was about 1/2 tank full, and drove 165 miles, I could see the power, engine power and noticed how smooth and noiseless the engine was running at "Cruising Speed" of 15 miles above posted speed, someone recommended , that I pour this fluid while the tank is about 1/4 full, refill the gas again so this time went ahead and refilled the tank back to "full", this time filled up expensive gas just to give the "Fuel Cleaner" additional power and filled it with "Chevron" top tier gas, and drove another 160 miles, WOW ! this car runs like new, no lights on dashboard.I think my wife will be proud of me.Today , I decided I use the second Can on my 2010 Honda Accord V6 EXL /NAV, which has about 90K miles (w/ half tank of gas), there has been few intermittent problem with the "ECO" mode software on these cars and recently had the lights come on, and a software update and "Spark plugs" were replaced under HONDA warranty,( Honda knows about this problem), They had replaced the spark plugspreviously, I did the same with this car drove about 25 miles now and refilled with Chevron "Top tier" gas, so far so good, the car is running smoother and see that the 3rd cylinder does not unnecessary kick in when the car is running in cruise. No dashboard lights.Next step is to observe both the cars for mileage improvement.Based on "Initial Purchase Satisfaction", based on previous "Use Satisfaction" based on my mechanics recommendation, is a 4-Star, I will say this product is pretty expensive it is like filling 1/2 tank of gas in some cars, will try to use it at least once a year.UPDATE April 22 2017 : Background : My car was giving about 480 miles/full tank (about 17.7 gallons/tank) After running the my Honda 2010 EXL-V6 Navigation with this product as described earlier, my Phase-1 of the treatment was completed, and I could feel the car running smoother, and the V6 power coming back at right time, also "ECO" mode started at lower RPM around 2200 rpm instead of 2500 rpm at speeds of 65-70 miles/hour, once this phase was completed ,my next gas tank fill was around 17.7 (gallons) with regular Shell gas, after running about 128 miles at about 1/4th tank , the full tank mileage has a potential is pegging at around 512 miles/full tank about 7% improvement in miles/gallon.
