I use this product long time
I use this product because diesel fuel is not quality any more. So Diesel Kleen made less soot

Great product!
I put a bottle of Power Service Diesel Kleen in my fuel tank every fill up.Can hear and feel the difference.It smooths out the cumming knock from ULSD and cleans and lubercates injectors and fuel pump.In the winter I blend with howes anti gel.Cheap insurance to prevent having my fuel pump chew itself apart and push the steel shavings through the fuel system.15k to fix and 1-2 weeks of with out the truck.

Great product! Fast shipping
Great product, have been using in my diesels for last 8yr. Can definitely feel and see the difference in performance and fuel economy. PSC price is great for bulk purchase and super fast shipping. I run it in my ‘95 6.5 Detroit diesel, ‘04 6.0 power stroke, and ‘17 Cummins with no complaints all year around. Will definitely continue to use and purchase from PSC.

Diesel Kleen +Cetane
Exactly what I was looking for to use in my 2017 Ram 2500 6.7L. Solved an issue that I was having and the price at PSC is unbeatable

Power Service Diesel Kleen
I use this product with every fill up. Engine runs smooth and start up is instant. With truck stop fuel cetane levels at around 42, boosting the cetane is a must for good engine performance.
-
Great product for our farm and construction equipment. Have been using for twenty + years.
My only complaint is the price of the shipping. Wish you would offer flat rate on LTL to Alabama

Dmax
Very good product and price. With today's fuel supply you can't be to careful. Helps keep my Duramax running smooth and clean. Only wish it were easier to pour into tank without having to use a funnel.

Dramatic improvement in my TDi
I love this stuff, i put it in everytime I fill up. In my motor I notice less delay in acceleration, smoother idle, without this I'd go about 400 miles in the city, with it I can make it to about 450-475, 550-600 on the highway probably more if I did not have a lead foot. On top of all that I find comfort in knowing my injectors are being cleaned out and fuel pump is being lubricated. Did I mention theboost in power! My car is a 2014 Volkswagen Jetta 2.0 TDi with a 15 gallon tank.

Proof is in the results.
Bought a 2019 Chevy drove it home, then went and bought the 32oz. Then I ordered from you in the 9/16oz it is easier to use. Took a 1400 mile trip to New Mexico. The best I was getting driving it home was 20 to 21. This trip speed limits are 75 most of the time, best 50 mile average was 25.3. I was wondering if and when it would regenerate. I had about 800 miles on it to my knowledge it still hasn't regenerated yet with 2500 miles on it. I plan on putting Diesel Kleen in at ever fill up and fill up on a half a tank every 4th or 5th fill up add none to keep from getting too much in the fuel.

Noticeable difference after first use
I have a 2014 RAM 3500 with a little over 50k on it and was noticing that the engine was not as quiet as when it was newer and I had noticed a little hesitation at times. I bought this product and added it before refueling the tank. Wow, I immediately noticed that the hesitation stopped and after a few days the fuel mileage for my standard daily commute increased by approximately 2 MPG. I'm sold!

5 Stars
As far as the product goes, I've always trusted Power Service and it's now endorsed by Cummins which is saying a lot for it. I use it as an additive to save the CP4 pump in my 2015 Duramax and will use it in my built 99 Dodge Cummins when I get done restoring it. As far as price goes, this is the cheapest by far! Yes, I have enough to last me a lifetime here but I'll always have it on hand and never have to go to a store to overpay for it. I placed my order in the evening after hours and PSC fulfilled my order and it was shipped the next day. My order showed up the 2nd day. I highly recommend PSC and will be doing business with them again for any of my other needs. Thanks!!!

Product does what it says
I have been using this product for about 2 years now and find that it makes my cummins diesel run much more smoothly and cleaner. I have less active regens, and get more life out of my fuel filters with this product. I have also noticed that my fuel economy is more consistent from tank or fuel to tank of fuel.

Soon-to-be lifetime customer
I run this in my semi truck every fuel up and I haven't had any issues yet I recommend buying the concentrated version and you only have to add point 0.128oz per gallon. The two and a half gallon jugs are the best deal. I'm glad I found this company hands down best price For this product. You won't Find it cheaper

additive
power service is a staple in the diesel additive world they have been around and trustworthy in everything the make
-
Good product
Since that I am using this product for quite a time I can tell that it helps with MPG at a (very) reasonable price. Noticeable is much smoother and less noisy engine operation. Other benefits I can't confirm but most likely they're there.

Excellent additive at a reasonable price. It helps with better MPG and keeps my injectors clean.

Great Product
Been using it since I bought my 2016 F-250 with the 6.7. No issues so far.
-
Best Diesel additive bar none!
Provides great Cetane boost, injector and cylinder lubricant and keeps your combustion system nice and clean. You will see a noticeable improvement immediately after adding this to a tank of fuel. Highly recommended.

Series 60 Power
I have and older(1997) Detroit in our Motor Home. It was built before the ULSD. This additive seams to take care of the lubrication that the old Diesel used to do.

DieselKleen works
I have used this in our 1996 Bluebird Wanderlodge motorhome powered by a Detroit Series 60 for the past 6 years(around 65,000 miles). No injector issues and it does give you a little boost in HP. Originally started to use it for the added lubrication because of the ultra low sulfur diesel.
