Berryman Products B-12 Motor Tune Up - 16 oz., (Pack of 12)

Berryman has been a longstanding name in the automotive supply industry and this stuff is definitely a treat for your ride. Not that my 2017 Kia Sorento AWD V6 has been neglected and I always fill my tank with 93 octane Shell or BP/AMOCO. Occasionally drop in a fuel injector cleaner or octane booster for added performance from time to time. Recently was the first time using an "all-in-1" cleaner and this potion does just that, cleans everything and provides smooth idle, easier acceleration and extra mileage. Whether you're driving a brand new high performance vehicle or the average everyday practical low HP 4-cylinder car, this stuff is well worth the 💰. Depending on how often you drive your vehicle, this is one of those once or twice a year tune up in a bottle type fuel system cleaners. Worth every penny and no need to spend $20-30 on some high end brand, Berryman will get the job done and they've been doing it for 100+ years now. A most highly recommended complete fuel system cleaner.

this stuff does help clean my diesel engine up and get rid of black smoke and makes engine run smooth and quit

Works as it should

Company always makes great products

Miracle worker! Had a noise coming from the valvetrain under load at low rpm, it's gone now! Follow instructions on the bottle for engine flush

My Father started me using this about 40 years ago and it really works! Do your car a favor and give it this treatment.

I don't know for sure if it does anything because I am no expert BUT I do notice my car running better overall after I run this with Exxon gas. I will use it for peace of mind if anything else.

This is the same formula as Seafoam. Should produce same results. Not sure why it’s double the price as Seafoam.

This stuff works !! Forget other additives Berryman gives noticeable results in half a tank !!!

I used to swear by Redex to add to the tank just to keep the injectors and fuel pump clean, I saw this on Vice Grip garage and then looked up the reviews, seemed to do what I needed so bought some, glad I did I used it in my car and bike with great results both seem more responsive and running more reliable especially with the carburettor equipped motorcycle. Recommend, however price is high compared to the US.

Well have used others but this now beats them all. Car running like a Dream. Even though it has high mileage cleaned all and improved both performance and fuel economy.

I've not used it yet but confident it is the best.

Worked very well, improved running and fuel efficiency of 15 very old freelander, no easy task. Tried to buy again but cannot find it!
