So many queries come in everyday regarding our wide array of products, so we’ve put together a list of a few frequently asked questions — all in one convenient place!

Transmission Stop Leak

How much transmission stop leak should I use in a 6 quarts transmission?

Great question! We recommend using one entire bottle of our Berryman Transmission & Power Steering Sealer (part #0712) in automatic transmissions. But please be careful not to overfill.

Chem Dip

I’m about to dip my carb parts, but my baseplate won’t fit. I’m going to have to put it in something else to clean it.  What should I use? I’m also concerned about rinsing with water.  Do I rinse the parts in the sink and let it go down the drain?

Thanks for reaching out! It sounds like you’re trying to use either part #0996 or part #0996C, both of which ship in a round, 1-gallon paint can. If that is the product in question, it is safe to temporarily transfer it to just about any type of container, including steel, plastic, and glass. Both of those part numbers are water-based, so warm water is also the best way to rinse them off. Once the carb cleaner has been rinsed off, you can let the base plate air dry or perform a follow-up rinse with carb spray or use compressed air to blow it dry. Per the directions, if either the base plate or the carburetor itself are aluminum, a zinc alloy, or “pot metal,” do not soak the part(s) for more than 4 hours. Instead, soak for 30-60 minutes and use a soft-bristle brush or even a toothbrush on all accessible surfaces and repeat the process, as necessary, ensuring a cumulative soak time of no more than 4 hours. Hope we were able to answer your question!

Fuel Injector Cleaner

Is the fuel injector cleaner best for cleaning — and is this a toss in the gas tank product? Will the can of B-12 that cleans entire fuel systems equal to the stand-alone fuel injector cleaner?

Berryman B-12 Chemtool Fuel Injector Cleaner (Part #0116) is an in-tank additive that is great for fuel injector cleaning under most circumstances. For more severe situations, we recommend B-16 High Mileage Fuel System Rejuvenator (Part #7516). This in-tank additive offers one-tank cleanup not only of fuel injectors but also intake valves and combustion chambers. If you’re looking for a stand-alone/thorough-rail cleaner, we offer a pressurized product version (part #1120) and a pour product designed to be used with a canister and compressed air.

I was wondering what the shelf life for the diesel injector cleaner is? I have two older bottles of it. Can I still use it?

Thanks for asking! Our fuel additives’ standard shelf life is two years, but they can last up to 5 years. We hope that helps!

Is it safe to use with 100% non-ethanol gasoline?

Yes! Berryman B-12 Chemtool Fuel Injector Cleaner (part #0116) was initially formulated for use with ethanol-free gasoline. However, it contains 100% high energy solvent technology or “H.E.S.T.” chemistry, so it is also compatible with all gasoline and ethanol mixtures, including E10, E15, and E85.

I accidentally put some in my oil crankcase, thinking it was oil additive. Should I be worried?

Our Berryman B-12 Chemtool Fuel Injector Cleaner (part #0116) is safe in engine oil up to 2 oz per quart of oil. Just start the vehicle and let it idle until it’s at operating temperature. However, you will likely need to change the oil and filter afterward.

Diesel Engine Fuel System Cleaner

Which additive is suitable for a diesel car’s injection system cleaning, equipped with a diesel particulate filter? Also, which one is proposed as a preventative measure and how often to use it?

If you’re only looking for cleaning and lubricity (as opposed to a combination cetane booster or cold-flow improver, too), then the best product for that application is Berryman Diesel Injector Cleaner (part #0518), which offers one-tank cleanup of both traditional and high-pressure common rail injection systems as well as a lubricity additive for the longer fuel pump and fuel injector life. Regarding the frequency of use, a good rule of thumb is to use the product every time you change the oil. However, you may certainly use 0518 more frequently if warranted.
