3 Pack Bg 44k Fuel System Cleaner w/ Bg Funnel - 3 Cans

Seems to be working well

BG 44K is the best fuel system cleaner, but it may take more than one can to truly have an impact. In fact, some shops have specialized BG 44K intake cleaning machines and they recommend doing that at the same time as running a can through your fuel tank. I've used it in several vehicles in the past and have been pleased with the results. I noticed my 2004 Audi S4, which had carbon build up issues, ran noticeably smoother after the 44K fuel system treatment, even better yet after the 44K intake treatment. Yes, BG products are more expensive, but as is with many things, you get what you pay for. You'll probably need to run 10 cans of that $3.68 Chemtool through the system to do what 44K does. I'm a huge believer in 44K and do my best to run it through my vehicles every 5,000 miles.

This stuff really works. Unlike other fuel system cleaner products where you hope or guess they work, you can feel it with BG 44k. I first put it in my 2014 Kia Optima (has a GDI engine). I can't say the car was running bad but I had noticed it had lost a little of it's pep since I first purchased the car. By mid-way through the tank of gas with 44k in it, I could already feel the pep in the engine had returned. Gas mileage on the highway is up about 1mpg which doesn't seem like much but when you commute 90 miles a day, I'm good with anything positive. I then put it in our 2007 Kia Sedona van. I purposely drove it on my normal commute (90 miles) and measured the mpg. Just like the Optima, the mpg seemed to have improved. The van when new was rated at 25mpg on highway. It was averaging more like 22-23. On yesterday's commute it measured at 24-25. No doubt about this product working.

I used this based on recommendation of a trusted service center. I have used Lucas and more recently Techron cleaner. This is on par maybe a bit better then Techron. Notice a small gain in mileage and ran smoother. Good purchase

Been using Bg 44k to clean fuel systems for two decades. Have not found anything better for this job. Twice each year, or every oil change, I add a can to a full tank of gas and run the entire tank through, using a heavy foot whenever it's safe on the road, to open fuel injectors for max cleaning. If you look at your oil on dipstick before this process and again after the tank of fuel is burned, you'll likely see a blackening of the oil if there were any carbon or gum or sludge deposits. Proof they've been removed. Now change the oil and filter hot, and let drain as long as practical. Out come all the trouble causing deposits in the drained oil. I have not purchased a replacement fuel injector nor paid for a fuel system flush since regularly using this great product. "Your mileage may vary," meaning don't neglect air filter, spark plugs & fuel filter if replaceable. These attentions don't cost - they pay! R.R. - Mechanical Engineer.

I just had almost the same experience as another reviewer. Fortunately, or unfortunately, the yellow funnel it comes with didn't fit on the cans. So I didn't experience the "spill" of the product. I'd be cursing up a storm had that happened. I had to use my pocket knife to assist the funnel in opening the access to the tank. Two little nodules at the opening that have to be pressed simultaneously in order to get access to the tank in my car and the yellow funnel is not wide enough to do this on its own. Just find a funnel with a tip with the same circumference as the metal tip at the business end of a gas pump hose, and it should work fine (test before you spill). My vehicle is fairly new (Purchased in April 2017), so I'm using the product to maintain its power and efficiency (Charger Daytona SRT8 6.4 liter engine). So far so good.

Here is a first impression review. I received the BG 44k fuel system cleaner promptly and it was very well packed. I ordered the three cans with the funnel that fits right on top of the can. The funnel was great to use and easy to put onto the can. The nice thing is that there is no way to spill and you can just tilt the can up and leave it until it is empty. If you use it, make sure the funnel is completely seated or it will leak. I had no trouble seating it but it does take some care. Use a rag or several paper towels when you remove the funnel because it will snap off abruptly and there is residue in it. Wipe it well and store appropriately. So far, I have put about 75 miles on the tank of gas and haven’t noticed any different performance. Not sure you’re even supposed to. Maybe when I fill next the mileage will be better. I’ll update when I fill up.

This was recommended by a mechanic friend of mine. If you have a HIGH Mileage vehicle, and haven't used this stuff or something similar on a fairly regular basis before, avoid it. It cleans very well, is designed to work by the heating and cooling of your engine, and must be used when you are going to drive through your whole tank in short trips allowing the engine to heat up and then cool down completely between start-ups. I do not recommend this for High-Mileage un-previously treated engines as it will knock off all the gunk built up in your system and cause problems during start-up, and may cause fuel delivery issues, because of gunk getting knocked loose and lodging somewhere in your system and blocking fuel flow.
