B-12 0116 Chemtool Fuel Injector Cleaner, 15 Ounce, (Single Unit)

I used to only use the B12 in my old truck and the GumOut in my much newer vehicles but the GumOut is much more expensive.I took my 2000 Dodge 4x4 truck that has 220k miles in for a tune up, it's been 130k miles since my last tune up. The mechanic is a friend, he called me asked if I'd recently changed my spark plugs because they looked new to him.130k miles on those plugs and they still look new. He said my entire fuel system was clean and it didn't need a tune up at all. My old truck runs so strong, I credit that to the Berryman B12.I use the B12 5-6x a year. Pour it in and fill up with gas, I have a 25gal tank. I change my oil with Havoline Pro DS High Mileage every 5k miles and change my air filter twice a year.

My #1 go too for engines that have been forgotten , I have had many successful runs , and carb clean ups by just putting this in the gas tank , and letting the motor eat ..

I love this stuff. I’ve used it multiple times for general carbon clean up, fuel injector clean up, I’ve even used 1oz per l of oil into the oil and driven the car for a few miles to clear stuff up. Works well at flushing sludge out from valves and general cleaning. For the price, definitely worth it.

Good product and good price

I have a 2010 Prius with now 206k miles. I bought it with 163k and it's burned oil ever since. Around 198-200k Oil consumption was getting pretty bad. 300 easy highway miles would burn half the dipstick. Easy highway miles used to burn 0 oil. It was all the city driving that would burn the oil.But yeah, I did a B12 piston soak, which is a bit of a complicated process and would be very lengthy to type out. Used about 6 cans. 1 of those in the gas tank, rest for the piston soaking. Required about 36hrs and a aircompressor with a flexible rubber hose. A borescope was a nice extra.Right after I completed that process, I put in Castrol GTX blend 20w50. I towed my boat 2-3 times and delivered packages as well. After about 4k miles, I didn't lose a drop of oil. Yes, I have a 16' crappie boat that I tow with a prius that has oversized AT tires and a lift.I recently switched to Valvoline high mileage blend 5w30. In preparation for Texas winter. I towed the boat once and only been driving to and from work. Maybe 300-500 miles on it so far. Somehow this oil has caught a lot of vapor/water oil in my catch can. I thought I installed it for nothing as over about 7k miles it only caught about 2 tablespoons of thick oil. Now all the sudden it's catching vegetable oil looking stuff? And quite a bit as well. Maybe a 1/4 cup. For those 300-500 miles.Doesn't seem like it's burning oil so far with the 5w30 but I will keep an eye on it. Either way, it's burning significantly less oil, comparatively.

fixed at least 1 vehicle for me
