Power Service 32 Ounce 3025 + Cetane Boost Diesel Kleen Fuel Additive-32 oz

Excellent product to keep diesel clean and performing well..Good price

My ol truck is 20 year old F250 diesel. Relatively low miles at 160K but tired. It has a inconsistent idle RPM when at idle with brakes on. I put a 1/2 bottle of this in with each full tank of fuel. Took a few miles but it did pretty much stop that….. and prevented it from coming back… I always carry one or two bottles of this in tool bo… truck likes it.

Not the lowest price, but delivered to my house so I always have a bottle in the trunk!

Helps a lot! This is a good product! Recommend!

The duramax has 200,000 miles on it. We had the fuel injectors replaced at about 95,000 miles and thought we would have to do that again. Last time it cost about $4,000 to replace the injectors, so after some research, we tried the diesel kleen. It's only been a few days, and have already noticed a big reduction in exhaust smoke, and the engine seems smoother at idle. Not sure if it's helping in fuel millage or not, but we have no complaints so far. Highly recommend .

I run 10oz to every tank full works very well

Noticed a smother sounding idle after using this.

Received the bottle and at least 8-10oz spilled during shipping. The fluid was luckily captured by the plastic bag inside the box. Used what I could. 3 stars for leakage.
