Review: High quality product - Works well
Review: Amazing - 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.

## Questions & Answers

**Q: Will this be safe on a 2008 4runner?**
A: As far as I know it's safe to use in any car that has a gasoline engine I use it in a 2003 Celica GTS

**Q: Would this hurt fuel pump?**
A: It could potentially hurt a mechanical fuel pump if you have an older car that is still using a mechanical fuel pump with a bladder/diaphragm. Electronic fuel pump should be fine but use this stuff up quickly, once you've added it to your fuel, you should go through that entire tank of gas in a short amount of time and preferably a long trip on the highway.

**Q: does it lubricate enginge and cylinders also ?**
A: Not at all.  No lubricant properties what so ever.  This is high detergent and high solvents.  Designed to clean fuel Systems, combustion chambers, at cats.  Great stuff.  But use it for it’s purpose.

**Q: What makes this "better" than regular B12 Chem Tool?**
A: Both products use the same powerful detergent package, but the Berryman B-60 HIGH-MILEAGE FUEL SYSTEM REJUVENATOR actually has just a bit more of the detergent package as well as a different solvent package. Either product will work very well but the B60 high mileage is slightly better-suited to clean-up older, neglected fuel systems.

### ⭐⭐⭐⭐⭐ Works for one good cleanout
*by A***N on November 8, 2025*

Bought a 2007 Rav4 4-cylinder without knowing about the oil burning issues with the piston rings. It started getting pretty bad, like a quart of oil per 300 miles. Seafoam or the normal B12 did not seem to help. Based on the review here, I decided to try it and let me tell you it works (at least the first time). It did make my engine misfire once (probably from carbon burning up) but after running it through the whole tank, oil burning is now about a quart per 1000 miles. Over time it has been creeping back up. I have tried using this again and the regular B12. It seems after using this once, the difference between using this and B12 is negligible so save yourself some money on future and just get B12. Now, I just use a B12 before every oil change and that seems to be keeping the oil burning at around a quart per 700 miles. Hopefully this keeps it manageable until the car gives out. I have considered doing a B12 piston soak but haven't found the time.
