## Description

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

Review: 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!!

## Questions & Answers

**Q: Does it work to fix catalyst problem**
A: If you're having a problem with your catalytic converter, I doubt it would fix it.  If the problem is being caused by clogged and inefficient injectors, it will help.  Be aware, that I used this chemical with an OTC fuel injector cleaning tool, and did not pour it in the fuel tank.  Using the B-12 with the OTC tool made a difference on all four of the vehicles I have cleaned the injectors on so far.

**Q: can i use this in a 13' Scion FR-S? its a gasonline- direct injection**
A: Due to the nature and problems with direct injection it will not clean the back of the intake valve like it will in a normal engine but it would clean the injector in the direct injection engine
Most engines that are not direct injected spray and it runs onto the back of the intake valve and cleans it off, a direct injection doesn’t spray  the intake valve

**Q: Anybody run this in a Honda 2000 generator?**
A: I have not but don't see why you can't I use it in my weed eater lawn mower   snow blower    my lawn mower has a Honda motor on it   it's been running great for the years I have owned it

**Q: Is this non-flammable product?**
A: No the product itself isn't extremely flammable but the arousal is. They make a chem dip that is works great in ultra sonic cleaners
