CRCMotor Treatment, 16 Fl Oz

My Mazda 6 was having bad pre ignition knock when the weather got hot and being in Texas that is a problem. Thought it might be due to carbon build up and used this product. I tried the Techron additive before and it didn’t make a difference. Within one day of adding the bottle to a 3/4 full gas tank the problem has completely gone away.I was surprised at how well this stuff works for carbon. I don’t know how well it cleaned it but it was enough to fix my problem.

After not having used my car for work or travel much in the past 14 months due to Covid, my engine was gunky and gas mileage had plummeted from the 21mpg average down to 14mpg according to my Toyota Sienna's on board estimate. I read a lot of reviews and watched some Scotty Kilmer videos on YouTube. This was highly recommended. Actually got this and the CRC MAF sensor cleaner. Have not yet used the MAF cleaner so my mileage increase is directly related to the CRC Motor Treatment. I put about 13 oz of the 16oz into my gas tank them followed it up with a full tank, approximately 14 gallons of gas then went out on the highway and drove about 70 miles round trip. My mileage calculator started off at 14mpg and quickly increased all the way to 24.6mpg! As good of gas mileage as I was getting in my van when it was brand new! Two weeks later and my mileage calculator still says around 19pmg in city driving. I only tried this in the fuel tank, have not tried adding it to the oil which is says on the directions to do. I purposely saved 3oz in the bottle for that and may try it this week. Will definitely update with those results!

F150 Ping n Rattle Fix. My truck had this nasty pinging and detonation and after furthur t/s i found out the IMRC valve had lost or drop one of the rods at passenger side cyl head, reconnected IMRC valve rod and no more pinging or detonation or rattling. I still continue to pour this into fuel tank since spark plugs on driver side cyl head were super carbon build-up, this product does work on removing carbon buildup. Will continue to use in the future. Great product. Truck runs smooth and strong and the best part. NO MORE PING OR RATTLE

It is a engine fuel fuel injector cleaner crc is a very trusted company after using this product my fuel mileage increases 7mpg,now this was used by myself after a class action lawsuit where they had to install new rings due to oil getting by the oil ring on the cylinder and the factory failed to address the carbon build up on the injectors this would get to be a long story but I bought 2 cans used one can on a full tank of gas and then when I filled up the next time I had a 6mpg increase in mileage and just for piece of mind after 2 tanks after first use I am using a 2nd can for piece of minf

CRC products are the best I have used in both my diesel and gas is something I will be checking out.

I Had a carboned up valve that was causing my "check engine" light to illuminate. This product cleared it saved me a ton of expenses.

Vehicle runs better ,slight increase in mpgs !

Purchased a car that sat at a classic car dealer for four year. Added CRC to the tank and all is good.
