I used this n gv me excellent results. Review: Amazing but risky - I can write a detailed review. But i will just summarise it. Be very careful when using it if u have a very high mileage car thats burning lots of oil use it at ur own risk. I followed the youtube method by removing the spark plugs pouring in cylinders every 6 hours. After the process was done i went on highway flooring the car to check no oil burning smell or check engine light. Unfortunately after 30km when i floored the car again from 0 by rngine head blew up maybe i shouldnt have stressed the engine soo soon could be user error. However my engine did blowup and oil flew up everywhere had to replace engine.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best product for Piston Soak *by V***A on 30 July 2024* Hi i had a issue with oil consumption in my car n after so much research i found piston soak using B-12 is the best solution.

The product is amazing but risky ### ⭐⭐⭐⭐⭐ A true miracle decarbonization tool for old cars! *by V***S on 28 April 2021* My daily "beater" is an old 98 Nissan Sentra SE. Quick intro explanation: So far an amazing car as I bought it five years ago on an auto auction for $1500. Back then the car had 188,000 miles on it. I've been driving around for five years and approaching 220,000 miles repair free ever since . I do good maintenance change oil and oil filter at the latest at 3000 miles or at least twice a year. I changed a full flush ATF fluid every 20,000 miles. The 2 L four-cylinder engine amazes me not only with the power it has (you can tell the soul of it comes from Nissan motorsports) but this is the first time have an engine with absolute it does not burn a single drop of oil! Nada. Zilch. Considering the mileage it has that is quite amazing! I once marked on the dipstick the oil level on a morning after the day of an oil change. 3000 miles later in the morning before going for no change I pulled out the dipstick and the oil was exactly on the same marking I made! I also tested compression on this four-cylinder engine and to my other surprise I am pretty much equal on all four cylinders with minute differences 2 to 3 psi! Amazing. It also is the first engine in a car that doesn't tip oil considering that the vehicle is 22 years old and has 220,000 miles on it! Amazing, amazing! The only complaint I have about this car is that I never achieved the city mileage of around 20 miles per gallon. The vehicle is officially listed as 20/27 city/Highway. Mine was always low around the lousy 14 to 15 gallons per mile Freeway going 65 does better and I get close to 22-24 miles per gallon. Not as great as specified. I spoke with a trusted mechanic about this who then mentioned clean out your intake with Berryman B12 and dump a can into the gas tank when you fill 'er up. You'll be surprised he said. I read and watched a few YouTube's about Berryman B12 and decided to give it a try. So I did that. And boy was I surprised! Following instructions I first slowly emptied a whole can into the running engine, with the other hand slightly opening and closing the throttle to avoid choking it off. I emptied gradually an entire can via a small hose by intake suction gradually before the throttle body. The first surprise came thereafter! Now suddenly my idle was about 400 RPM higher running. Instead of 900 now at 1300 RPM! So I readjusted the idle air screw so that the idle RPM was 900 again. Then I started to drive around mostly city driving and noticed that the engine was much more responsive and I could be very light on the gas to move her. Next time I gassed up I added a full can Berryman B12 in the gas tank. I drove around mostly city and some short freeway drives. I noticed the car was "feeling" and driving better and definitely much more responsive. Next time I gassed up I measured my fuel economy and what was in city driving usually around lousy 14-15 miles per gallon was now after the treatment suddenly 20 to 21 gallons per mile! I couldn't believe it! I gassed up since twice and every time results shows a significant increase in miles per gallon, city driving and/or Highway. That is amazing! I can say safely now that after having driven several hundred miles that my average city mileage is around 21-22 miles per gallon and on the highway! The car performs considerably better and stepping full on the accelerator boy does she take off like never before! Berryman B12, Truly awesome stuff that evidently really works and does the job! ## Frequently Bought Together - B-12 0116 Chemtool Fuel Injector Cleaner, 15 Ounce, (Single Unit) - Gumout 800002231 Carb and Choke Cleaner Jet Spray - 14 oz. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/254052249-berryman-products-b-12-fuel-treatment-15oz](https://www.desertcart.tn/products/254052249-berryman-products-b-12-fuel-treatment-15oz) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-14*
