You know how they say you wish you had the old stuff the old stuff work better it was pure. This is it! This stuff has been around for 50 60 years or more and it works like a charm and it’s cheaper than the so-called name brand and it works better because it’s more concentrate. I used it in my cars I use it in my small engines. I’m going to try it in a chain saw that has been sitting for years with gas in it I’m 100% positive it will clean out the carb an it will will run. I’ll have to up date that here.

I’m very happy with the product as I am seeing two miles more per gallon and crisper performance in my 1998 Ford Ranger extended cap with a 3.0L V8. I also notice less dieseling when in a high gear at low speed under acceleration. I’ve ordered another case to maintain the performance.

We’ve been using Berrymans B12 Chemtool for years and have never had to have our injectors cleaned. We give it to our kids for Christmas!

Product arrived on time and well packaged. People who know no that Berryman’s is a great product and buying in bulk is a great way to save a couple bucks over time especially if have multiple cars.

Keep your fuel system clean, and your vehicle will run much better, for longer, without lots of trouble. I really do recommend this product over all the others I’ve tried.
