3 set 0116 B-12 Chemtool Carburetor, Fuel System and Injector Cleaner, 15 Ounce, (Single Unit)

Hard to beat cleaner...been using it in an old jeep tj for years....

I use this in my 2019 Infiniti QX50 about every 3,000 miles plus only use Top Tier gasoline. Over 83,000 miles and still running like new.

My 2019 Kia like most older modeks kias havevoil burn issues. About a year and a half ago It started giving me problems with acceleration and hesitation with some weird rattling sound. I saw 4 different mechanics ( including kia dealership), spent around $3000 on parts I didn't have to replace, and was about to get rid of the car. I heard of B12 and decided to give it a shot. I put 91 gasoline on an empty tank and added this. Within few days, the rattling was gone. Acceleration got so much better. And I only used 2 bottles. I also saw they recommended another product of the same brand that deals with high mileage and cars with fuel system that was never treated. I added it yesterday. I usually don't leaveclong review but I had to share my experience cause this product well worth it. I wish I knew about it before wasting so much money and frustration. Highly recommended.

My husband uses this on our 2014 Outback. it’s terrific and perfect for our freezing cold weather we have been having. Since using it 2 yrs ago the Outback has been starting up and running much much better. This is a definite goto for our older Subaru. Best product ever and only improves how our car is running.

Tip: Whenever you buy gas for your lawnmower/generator/pressure washer/etc, add this to the can. That way you treat all your gas powered equipment and don’t have to think about putting it in the individual fuel tanks. One bottle treats all my small engines for an entire season. Great way to keep things humming along, and never have to worry about draining the gas.

All showed up badly damaged but still holding all fluids. Always use Berryman to clean up my fuel system every few months.

Apparently this is nearly identical to BG 44K from my research at 1/3 the price so I gave it a try. I am very meticulous with all my vehicles so I add one of these to my gas tank on each oil change. Too early to tell but I love Vice Grip Garage on YouTube and he seems to love this product so I’m giving it a shot. Great value for the money, ease to use without the need of a funnel and you get three for the price of one BG.

Cleans piston heads really good with 24 hour soaks. Just make sure you have a air compressor to blow all the carbon out. 75 PSI was the minimum to make it all shoot out.
