Best value and it works!

I've used Berrymans B12 fuel injector cleaner several times on my 2018 Toyota RAV4 and my 2015 Toyota Camry. It fixed issues with rough idling, slow acceleration, acceleration hesitation and stalling. First can results! After researching this I've found out that lower fuel quality in general is what causes the issues so this is not a one and done solution. I mainly use Shell and Texaco fuel stations so its not like im using no name fly by night stations. Fuel quality is just not what it used to be. I use Berrymans after the issues recur and it clears it right up each time. I haven't tracked it but I'm guessing I've used it one out of four fill ups. More on my 2015 than my 2018. This product does what it says it will do at the best price for what it does- which is clean fuel injectors. If you're looking to get your car running better and you don't want to pay a mechanic $150 or more for fuel injector cleaning service, Berrymans is the best solution I've found.

"It may not contain PEA but it works just as well. Yes, you might need to use it a little bit more often but the reasonable price makes that a non-issue. We love the way it makes the car run so smoothly. Our car is more than a few years old and this product makes sure your car still has that ""giddy up"" you need

Magic bullet right here.

For years I have been using Berryman's B12 for routine maintenance and deep cleaning. Where I currently reside it gets pretty cold for a few months out of the year, people Park there carbureted toys for several months and call me up wondering how much it's going to cost them to make it run right again and I tell them about $10. What you need to do is throw in a can of this stuff right here and fill your tank with some premium fuel and let it work its magic. This stuff will absolutely clean up any residual residue from bad quality fuel or gas that sat all winter. You can also use it for preventive maintenance like adding it to your tank before you plan on storing it to act as a fuel stabilizer or simply pour in a can a few times a year to keep your fuel system sparkly clean. Other brands like Seafoam have national recognition for their long-standing reliability but this stuff works just as well if not better at half the price.
