Review: ممتاز - منتج جميل وفعال Review: Exceeded my expectations - 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. ## Features - It is effective - Easy to use - Use as directed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DDVU6EI | | Best Sellers Rank | #158,896 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #2 in Motorhome Cleaners | | Brand | BG | | Brand Name | BG | | Contains Liquid Contents | Yes | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.6 out of 5 stars 1,938 Reviews | | Item Volume | 11 Fluid Ounces | | Item Weight | 0.31 Kilograms | | Manufacturer | BG | | Model Number | 44k | | Net Quantity | 11.00 Count | | Part Number | 44k | | Scent | Unscented | | UPC | 614131022208 | | Unit Count | 11.00 Count | ## Product Details - **Brand:** BG - **Contains Liquid Contents:** Yes - **Item Volume:** 11 Fluid Ounces - **Item Weight:** 0.31 Kilograms - **Manufacturer:** BG - **Net Quantity:** 11.00 Count - **Scent:** Unscented - **UPC:** 614131022208 ## Images ![44K Fuel System Cleaner - Image 1](https://m.media-amazon.com/images/I/61dnY1KqpqL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ممتاز *by A***N on 25 October 2025* منتج جميل وفعال ### ⭐⭐⭐⭐⭐ Exceeded my expectations *by K***E on 12 August 2019* Used this on my 2011 Audi A6 3.0T with 100,000km (62k miles).

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. ## Frequently Bought Together - BG 44K Fuel System Cleaner Power Enhancer 11oz. - BG Advanced Formula MOA 115 - BG109 Compression Engine Performance Restore BG EPR --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/378346189-44k-fuel-system-cleaner](https://www.desertcart.be/products/378346189-44k-fuel-system-cleaner) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-22*
