I have been advised by Jaguar Techs, Mercedes Techs and GM Techs, that BG-44K is like a shot of penicillin for the whole fuel system, right down to the injector tips and upper cylinders parts...This stuff is awesome...I've been using BG-44K since the early 2000's..I use to use Red-line SI-1 for ever since I can remember..but it always said use it in every tank full..And I never had any problems. BG 44K comprises a bunch of chemicals that even though are harsh, are safe to use on the engine and fuel system.

The other difference entails the level of concentration of the additives. BG 44K features a higher concentration of additives than its counterpart and that’s why it is used as the last alternative or on cars that have a very dirty fuel system. How Are They Similar? 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.

Product Details

As a result, you enjoy better performance. BG 44K also does a marvelous job at conditioning the fuel system with its sweet scent. This product boosts fuel economy and you will enjoy better gas mileage. While this particular product is NOT suitable for diesel engines (you’ll want the BG244 for that), it does boast such great benefits for regular fuel engines that users across the world are giving the product a big thumbs up! Today, BG 44K products are still among the leaders in global transportation maintenance services and other similar industries.

Now, if you want regular maintenance of your fuel system to keep it clean and well, take it as a rule of thumb to use the BG 44K for every 5000 miles you drive. However, since this product has quite a short instruction on it, it doesn’t help the users, especially those who can’t understand the effects of fuel additives. Every BG product, especially the BG 44K Fuel System Cleaner and the BG 44K Fuel Injector Cleaner, are all for professional use. It adds more efficiency, miles per gallon, and long-lasting reliability to every vehicle that needs it. Both get rid of carbon buildup and sludge in your fuel system. If your goal is to clean the entire fuel system, both these two fuel injectors are great at that. And what we love about both is that they also treat the carburetors and pistons. What’s Better about BG 44K?If mainly used for fuel issues/cleaning and not carbon issues then I would opt for Redline SI-1. Redline cleans fuel injectors/systems very well. I usually save the BG44K for fuel systems/engines that I know are very dirty or that have a known problem with carbon build up. The container comprises 11 11-ounce of high-quality solvents that when flushed down the gas tank, cleanse the entire system thus enhancing the performance of your vehicle. It may take multiple applications of the BG44K Fuel System Cleaner to experience these positive changes in smell. In some cases, it could not be possible, due to carbon deposits, dirt, and waste build up in your system over time. Even through the conditioning process, if your engine is burning oil and other carbons, you may not experience the nice conditioning smell of this product. The BG 44K works just like any other fuel system cleaner and fuel additive around. You pour it on your gas tank, and it mixes with your fuel, providing a cleaning agent to help clear out the system and improve performance.
