Review: 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 desertcart.
Review: 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)

## Questions & Answers

**Q: Will bg 44k hurt my engine if i fill it with chevron gas that has techron already in it?**
A: I routinely use gas from Shell (V Nitro) and Exxon premium. I even buy bottles of Techron in addition to what's already in the gas from the pump. They don't do much. Once I put in BG44k into the tank (and drive it for about one tank's worth of miles), I can feel the power in the engine come back. Feel, meaning, the car pushes you against the seat more when you floor it. Only BG44K does that.

**Q: Whats the difference between this and the fuel system cleaner?**
A: Chris, I don't really have experience with other fuel system cleaners. I used BG44 on my engine builders recommendation. I was having problems with my racing engine building deposits on the valves and increasing leak-down percentage. With several cylinders showing 6 to 8 % leak down, I  ran the next race with 1/2 can of BG-44 in 5 gallons of 110 octane rave gas. After the race, those cylinders were all below 2% leak down. Also the intake manifold runners were sparkling clean. I now repeat this process after 40 or so 1/4 mile runs and all cylinders are still between 2 and 3 % leak down.

**Q: 2008 saturn astra with fuel filter in fuel pump-will it clean this filter?**
A: Hi 44k is strong stuff and will clean and condition ALL parts of the fuel system. Filters included.

**Q: Is this necessary if i use top tier gasoline?**
A: I use top tier fuels (always 93 octane), but I have read and studied American Society of Petroleum Engineers findings for years.  With minor exceptions all cars from 1986 forward are electronically controlled by computerized fuel injection systems, and most recently direct injection systems that place the fuel delivery nozzles in close proximity to the combustion chambers.  This creates a cleanliness hazard to the injectors.  So, you can avoid a $150-$200 carbon depletion cure with 1 can of BG-44K every 5000 miles or less.  Yes -- it is expensive, but if you look for sales and buy in bulk you can get it for half the retail price.
