B-12 Chemtool Fuel Injector Cleaner, 15oz (3 Pack) - 0116

Used to be much cheaper ~$4 and available as singles. Still a good value and great maintenance product. Has saved me some carb rebuilds. Also annual car maintenance.

Works great mixed with chainsaw gas for older saws.

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.

Works great

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

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.

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.

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