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 mileFreeway 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!

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. I used this n gv me excellent results.

VERY effective and potent! Don’t mix it too strong or it will eat up your gaskets! It is great for removing any residue and gunk build up due to ethanol! Do not use ethanol in small engines! This stuff is better than sea-foam and more affordable! It works!

Im a true believer in this . My Range Rover and Audi are 100% fixed from using this product . A couple years back my Audi 2.0l developed the common oil burning from piston ring issue . I removed spark plugs and put 1/4 bottle in each cylinder 4 times over a 24hr period . In the burning I crank it over without spark plugs to empty the cylinders. Then did a fresh oil change. 100% fixed . Never burnt oil again . Range Rover was experiencing long crank after sitting over ight from a leaking injector . This was also contaminating my engine oil . I put three bottles in a tank of fuel as a last ditch effort before replacing injectors . I’m only half author the tank of fuel and the injector issue is resolved completely. This stuff is incredible.

Went from burning 1L of oil/300km to half a litter per 5000km!

Not only did this clean my fuel injectors, but it removed the dents in my car from a previous accident. Check out the pics of before and after using Berrymans. It’s truly unbelievable. .

I have used a variety of carb cleaners in motorcycles, cars, and trucks over the years, and the B-12 products all way seem to be one of the stronger choices when things are really gummed up (sometimes too strong for rubber parts). I recently had a 30 year old truck that sat too long and got really rough and low on power. This stuff did a lot to smooth it out after a few tanks of gas.
