Berryman (0116-12PK) B-12 Chemtool Carburetor/Fuel Treatment and Injector Cleaner - 15 oz., (Pack of 12)

Good product. Used it for years. Never had an injector issue. Also bumps up mileage.

I put this stuff in every car I own, every fill-up, religiously.All my vehicles run beautifully. Really helps reduce fuel dilution of engine oil by keeping the injectors operating perfectly which helps reduce ring-pack carbon buildup (which causes engines to consume oil - domino effect).Best value/performance available.

A+++++ My go to carburetor and fuel injector cleaner. When my vehicles and small engine lawn equipment isn't running at full potential this is the product I run to immediately and after a full tank most problems cease to exist. Since I've gotten wise and stop using Ethanol gasoline (ask any certified small engine mechanic) in my small engine lawn equipment I don't have many issues anymore, but at the end of the season I still run about a half cup of this amazing B12 Cleaner through the system before long term storage using Non Ethanol gasoline. For my vehicles when acceleration issues show up I put an entire can with about 1/2 - 1/4 tank and go on a long high speed/ high RPM trip to completely empty the tank followed by a full refuel and it always stops the sputtering, slow acceleration, and even tiny backfires that show up periodically.. Definitely a High Grade cleaner but be careful this stuff will melt regular cheap plastics but won't harm high grade polymers. If you have a Rifled Shotgun barrel and use Sabot Slugs add a few CC's to your favorite bore cleaner and watch the sabot residue disappear just be sure to completely dry out your barrel and thoroughly coat it with your favorite oil or gun grease before storage. B12 has the best value for the money, and ease of use with multiple uses around the homestead I highly recommend everyone keep a few cans handy, it's truly an ESSENTIAL MUST HAVE PRODUCT... Thank you for supporting America and it's Armed Forces!!

If you haven't tried this, I bet you'll like it if you do. My 6 year year old Husqvarna trimmer and blower were hard to start and bogged when throttle was applied and generally ran like crap. Tried a few things without much effect. Pretty much was thinking of buying new. BUT, thought I'd try this stuff, didn't measure, because I didn't care, just poured some in and within a very few minutes they were running and starting great, and still are. So ordered me case of this stuff, putting it in ever gas powered thing I have. But I do measure it now.

Product works very well to clean dirty fuel injectors and also improves our gas mileage. I use it in our 2018 Nissan Pathfinder every couple of tanks.

Great cleaner

This works very good

Works great !
