Power Service Diesel Kleen + Cetane Boost

from googletrott

I used 1/3 off a bottle in my 20 gallon tank when I filled up and I've gained about 2 mpg on my fuel efficiency. I've also noticed it's idling a bit quieter. Would recommend this product for anytime with a Colorado or canyon that has a 2.8 Duramax.

My husband buys this for my diesel jeep and swears by it.

Diesel Kleen Cetane Boost really works in my 2015 Duramax diesel ! Runs nice, gets 10% better milage.

I recently started using this product over the past several months. The truck runs better. No considerable lag while accelerating. Fuel economy has increased by a small number but every little bit helps.
