Berryman Intake Valve and Combustion Chamber Cleaner, 16-Ounce Aerosol

Très facile à utiliser et très efficace je le recommande fortement

This product is freakin amazing. Ignore the negative reviews, those are people who have no clue. I ran one can through my 2012 Jeep Liberty V6 that was getting 12-16MPG and had poor pedal response and no acceleration. I had put plugs and wires, air filter because we just bought it for my daughter and it had 118k miles on it. We took compression test and it was fine. Narrowed it down to possible carbon buildup. Well CARBON BUILDUP INDEED! This thing smoked during the entire can during idle and almost none when driving. Immediate increase in acceleration. Fuel mileage restored to 15-19MPG, which for 118k miles is good enough! I felt the car had more to give so today (a week after the first can) I ran a second can through. This time it did not smoke during idle, but on the road test it burped quite a bit of smoke and the check engine lite came on and went off. no big deal. I was right, she did have more to give! I got MORE acceleration the 2nd time! At the time of writing this, I did not have the mileage into it to retest the MPG, but I will this weekend. I suspect 16-20MPG now. FREAKIN AMAZING STUFF for under $40! NO brainer! I also ran a can through my son's 2014 Chevy Sonic 4cyl (68k miles) and it did not smoke at idle. During the road test, It was sputtering badly to the point I had to use manual shift to rev up the RPM's. Check engine lite blinking. I stopped, let the engine recover and pulled out onto the main road. It started to accelerate and then almost died. I lost all power momentarily. Then this Hiroshima cloud came out the tailpipe, HOLY CRAP WAS THAT A MASSIVE DENSE CLOUD! Afte that, it cleared up and once again, we got the same results, much better acceleration and a 2.4MPG increase, it now gets 29MPG city! (prior was 26.6MPG). I ordered 2 more cans to run through my 2012 Silverado with 788K and my wife's 2017 wrangler with 50k. These cans are worth the investment, you immediately get it back and then some in recaptured MPG, let alone the better performance factor.

Facile d'utilisation et semble avoir un effet positif. Par contre, je n'ai pu le valider car je n'ai pas de caméra pour vérifier le résultat avant/après. J'aime le fait de pouvoir l'utiliser seul, et je recommande de faire une vidange d'huile après ce traitement pour éviter de contaminer les composantes avec le carbone qui se dissout dans l'huile et les gaz d'échappement.

5 stars for ease of use and the included attachments. This is the way to go unless you have a helper. Took the intake hose off on both ends (from throttle body and airbox) so I could make sure the yellow hook attachment was seated properly and pointed to the center of the throttlebody. Didnt have any pooling issues or leaks. Started up right away and drove around my neighborhood and kept it at the speed limit. Yes it costs more than CRC but then again its set and forget unless your car stalls or something. I got the can going and cleaned my windows. Just easier and faster. Im starting this on a one year old car and planning on using it every year.

2013 Mini Cooper S. Had a P0303. Already put in new plugs and coils. Ran additive in tank, with no change. Thought maybe it was fuel system, an might need to swap injectors. Bit more research and saw these cars are horrible with carbon build. Decided to give it a try. Throttle body is under intake on backside of engine, so had to inject the stuff a little further upstream. Didn't change idle at all, and no smoke while can was connected. But after sitting ~20 minutes, car smoked bad. Drove it until it cleared. Then drove it hard to try to get misfire again, nothing. Drove more to get it to try, nothing. Accelerated smoother, and so far so good. Haven't driven enough to see if mpg has changed.
