Power Service Diesel Kleen + Cetane Boost - 12/32oz. Bottles

Great product have been using for years in all my diesel rigs equipment etc and at a great price lifetime customer!

I use this product religiously in my 1987 F-250, 6.9l idi. I notice immediately, increased performance and less of that “diesel rattle” from the engine.

This stuff works.... period

Good deal on what seems to be a great diesel additive. Highly recommended.

I put a few bottles through my Cummins pickup on a trip from Florida to Colorado and back to Florida. Mileage may have improved slightly, but I could tell a difference in throttle response. I also noticed smoother idling and quicker regeneration cycles. Recommended by Cummins is a BIG plus! Peace of mind - I think it’s worth it to keep injectors clean and pump lubricated. Each bottle treats up to 100 gallons…I used 1/2 bottle per every other fill up (slightly higher concentration). Happy motoring.

Love the product, have used it for years but the description says 12 each 32oz bottles and package delivered us 12 each 28 oz bottles. Not sure where the other 48 oz went but I did not get them!

Starting running this right around 10K on a new Cummins diesel. I did before and after mileages with three different tanks to really see if i was getting any bumps. My driving is mixed about 75/25 highway to city and I do 1000 miles a week on average. Three tank average without was 16.9. Three tank average with was 18.4. That's doing the math and not using the onboard estimator. That 1.5 mpg bump is good enough for me. I also noticed that it ran a little bit quieter too. not as much injector noise though admittedly that could be in my head. Either way the product works and if it help prolong the life of the injectors even a little then thats just a bonus.

This product is highly the one fed by Cummings diesel and keeps our engine running smooth and quiet under any conditions
