Your cart is empty.Thoroughly cleans entire fuel system of all high mileage gas-powered vehicles, including those exceeding 60, 000 miles. Powerful detergents and H. E. S. T. solvents give one-tank clean-up of fuel injectors, intake valves, carburetor, and combustion chambers. Dissolves fuel residue and carbon deposits to restore lost power, reduce rough idle and hesitation, restore octane requirements, and improve overall drivability.

Great product but the price has doubled since July 2023

Went from 22 mpg to 27 mpg in Kia soul 2016. Amazing. I notice less oil burning too. Changed PVC valve too.

I’ve used this Berryman high mileage cleaner several times so far and it has really smoothed out my 4.0 v6 Tacoma . Noticeable difference in engine response and idle . I think it’s an essential weapon in your arsenal against the effects of ethanol gasoline.

Assumed I'd be wasting $19, but thought it might be a low/no risk fix for a 2011 Honda CRV with oil consumption issues. That engine was poorly made and suffered from some piston ring stickiness that leads to blow by, oil consumption and PCV fouling.Prior to this, tried a number of other non invasive things including replacing PCV.Pre treatment: Oil consumption of 1 qt per 1000 miles (.95ml / mile) using 0w-20. MPG 21-22 on 80/20 highway/city. Oil smelled strongly of fuel, suggesting perhaps fuel dilution also happening. Spark plugs 1,2,4 looked fine. Plug 3 had some oil fouling on it. I suspect that's the cylinder with the oil control ring issue.Process:1. Fresh oil 0w-20 change.2. Added the Berryman high mileage to full tank. Ran tank nearly empty, refuelled.3. Verified oil level.4. Took some road trips.Results:Two road trips of about 1400 miles. Hot weather (90F), interstate driving at 70-80mph for 16 hours total engine time. Up and down hills. Aggregate fuel economy over the 1400 miles via the onboard: 24.3 mpg. (Previous 21). Oil consumption: 500ml (.35ml / mile).This type of driving is the worst case scenario for oil consumption. High load, high speed, high heat. Post treatment there was a ~2 mpg increase in fuel economy, and 63% decrease in oil consumption.It's a little early to claim victory on this, but I'm genuinely surprised. I didn't change any other variables except the Berrymans.Conclusion:If you have a minor issue of a gummed up oil control ring, you might get good results from this. It seems to have helped compression (I didn't check with a gauge so all anecdotal) and fuel economy (also increased compression).

Used on my motorcycle 8k mi victory hammer, sat for over 3 years amazingly started up put sea foam in 1oz/gal. Rode short distances ok. But the engine started hesitating, no power when I throttled kept feeling like the bike was going to putter out. I was told by a shop it could cost upwards of $1500 to change the entire fuel filter system because it’s inside literally in the gas tank. Before paying all that money I first did some long overdue maintenance changed the oil, spark plugs, cleaned out the KN air filter. And while it would idle ok when I rode, same issue hesitation when throttling no power. Almost called the mechanic, but I read about people’s success and luck with Berryman. And the reviews are not kidding! I put an ounce, maybe a little more, because I eyeball it along with 1 gallon of fuel, because I wanted it to be concentrated. Let the bike run for 30 minutes and took it for a ride no more hesitation. I did a second round of the Berryman’s 1oz/1gal of ethanol free fuel from the local Wawa seems the only place that has ethanol free. And with the oil change, spark change air filter, and of course the star of the show Berryman it did the trick the bike runs like new. do I probably have to change out the fuel filter at this point? She’s purring like a kitty at this point so if it ain’t broke…There was a lot left I put it in my suv 20-6 Lincoln Nav L and noticed more power, smoother and quieter engine, can’t even tell if running.Used sea foam, Lucas, chevron, fuel cleaners, they don’t hold a candle imo to berrymans.

I have an older Bobcat 742 skid steer with the 4 cyl. Ford engine. The engine was rebuilt 2 years ago but was not running well. Would run for a little while and then stall and die. When it was running it would not take any sudden throttle. If you increased throttle it would stall. I replaced all filters and plugs and also used a spray carb cleaner with no improvement. On a recommendation, I tried the Berryman B-12 and got some improvement so I ordered the B-60. I got a steady improvement over about an hour of running. (actually a couple of 15-20 min sessions) It is now running great and has been for the last six months. Never better. Unfortunately it seems to have affected the fuel sender which went bad during this period. I was able to replace that for $20 with an aftermarket Doorman for $20 and that is still working after a few months. I highly recommend trying this Berryman product. It worked where others failed and saved me a difficult carb repair.

WORKS damn good. Easily noticeable improvement in response, gas mileage, and performance on a 06 honda with 275k. If this dosent help you have more serious issues. 1 can on full tank another at half full, and wow. 4k miles later it still runs great. Ill never buy another brand
