"This product more than pays for itself."

Loran Maggi, Soldotna, Alaska
2000 Ford F350 7.3 Powerstroke

"I just got home and wanted to share this with you. I bought my truck new in 2000 and have always gotten in the range of 10 / 11 mpg. In May of this year, 2007 with 102,000 miles on it I drove from Alaska to Washington state to pick up a new 5th wheel trailer. Before leaving I put "Diesel Kleen +Cetane Boost" in it for the first time. At every fuel stop I checked mileage, and added more Diesel Kleen, about 10oz per tank. I noticed a gradual increase in mpg at every fillup topping out at 17.3 to 17.6 mpg for the last 3 tanks of fuel for the trip down. On the return trip, pulling a 31ft 5th wheel trailer I averaged 10.2 mpg. With the cost of fuel as high as $5.25 a US gallon in parts of Canada this product more than pays for itself. Thanks"

"My mpg went up to 8.3. That’s unreal in one day!"

Ron Love, Greensboro, NC
1997 International Daycab

"I drive a 1997 International daycab with an M11 Cummins, 10-speed transmission. I fueled up both 100-gallon tanks, then added one 32-ounce bottle of Diesel Kleen to each tank. I could tell an immediate power difference, but the major notice was mpg! My mpg was 7.8 prior to this. After driving 500 miles that day in city and highway conditions, my mpg went up to 8.3. That’s unreal in one day! Thanks for making a product that does more than you expected."

"Power Service is not just for improved driving, it is for parking that vehicle as well."

James Glenn, Waco, Texas
1993 Dodge D250

"In October 2006 one of the ball joints went out on my Dodge Cummins D250. I started driving our spare vehicle. The next week my wife broke her leg in three places. We also had several medical problems and major appliances go out so the Dodge sat unused for 11 months. I started using Power Service silver in an ''82 Mercedes I had, and always used Power Service in the Dodge. After replacing the battery, I finally got the truck to a garage in September 2007. Using the same fuel it was parked with I had started it every few months, and finally I have been able to use up the rest of the 3/4 full tank. I TRULY BELIEVE the Power Service in the fuel kept the it fresh, and kept the injectors and injector pump from sticking up during this long down time. Power Service is not just for improved driving, it is for parking that vehicle as well. James Glenn, Waco, Texas."

"My fuel mileage increased 2 mpg in the last 3 tanks of fuel."

Chris Schulz, New Egypt, NJ
2005 Cummins Turbo Diesel

"Lately filling my truck with fuel was a real chore. The truck was running poorly to say the least. Rough idle, very noisy and my mileage has fallen a bit. A recent purchase in Walmart has solved my problems and concerns. I bought the Diesel Kleen +Cetane Boost. I went right out and poored the recommended amount into my tank. Later on that night I noticed the truck wasn''t as noisy and my idle had gotten better. By the next fill up, my trucks idle was smooth, the engine was the quietest it has ever been. My fuel mileage increased 2 mpg in the last 3 tanks of fuel. This is a great product that pays for itself. I am happy that I found your product and will always have a bottle on hand. I will have the Diesel Fuel Supplement in the winter to prevent gelling. Thank you for a product that works as advertised if not better!"

"I now run Power Service everytime I fuel up and tell all my friends with diesels to do the same."

Jason Laws, Macedon, NY
2005 Ford F350 4x4 CC LB Lariat 6.0

"I recently made a run from upstate New York to Florida and back pulling a large enclosed trailer. On arrival in Florida, my girlfriend and I loaded her mother''s car, and entire houseful of possesions into the trailer, and drove back to New York. I used Power Service Diesel Fuel Supplement +Cetane Boost on the trip. The truck ran quieter, with increased fuel economy and more pulling power. On the way down with the empty trailer, I had to keep checking my mirrors to make sure the trailer was still there! I was able to pull greater speeds uphill, with less downshifting under heavy load. I now run Power Service everytime I fuel up and tell all my friends with diesels to do the same. Thank you Power Service for making a product that lives up to its promises. I''m sold for life."

"When pulling my trailer my fuel economy barely changes from not pulling a trailer."

Nate Peterson, Chaska, Minnesota
2003 F-350 7.3liter powerstroke

"This stuff is amazing. My truck idles significantly smoother, starts faster and smoother, mpg''s increased 1-5 mpg, and has more felt power. When towing my trailer my fuel economy barely changes from not pulling a trailer. I have been in northern Minnesota when it was -25 degrees, truck sat out over night, not plugged in, started right up the next morning like it was 40 degrees. Absolutely amazing products. I run Power Service products in every tank of fuel, I''ve convinced a few of my buddies and neighbors to use it also, they are all extremely happy as well. I have also noticed a drastic reduction in the black smoke out the tail pipe under hard acceleration meaning less emissions and less wasted fuel. I have tried many other brands of cetane boosters and system cleaners, none have performed as well as Power Service, none of the others tried compare in price as well. I purchase Power Service products by the case, and will continue to do so as long as I own a diesel. Thank you Power Service for an outstanding product."

"Our fuel mileage has increased 2- 3 miles..."

Preston & Pamela Self, Indianapolis, IN
2004 Dodge Ram Turbo Cummins

"We have a 2004 Dodge Ram Diesel pickup. We moved to Indianapolis from Alaska and started using the Power Service (it was not available in Alaska); and our fuel mileage has increased 2 - 3 miles, the performance of the truck has increased and we just love it. We can filll up on a Friday with a half of a bottle of Power Service included and we can go a full 2 weeks on a tank of fuel. This is our only vehicle, and it is driven every day to and from work places. I wish Power Service were available at more places than Wal Mart. (That's the only place I have been able to find it so far). My husband is a Diesel Machinist and he swears by it; and he has started putting it in all of his employer's Wrecker and Towing Vehicles and their mileages have improved also. Thanks Power Service!!!"

"The first thing I noticed was easier starts and a much smoother idle."

Bob Ciaccia, Conshohocken, Pa
Caterpillar 3406E

"A few weeks ago I added a gallon of diesel kleen with cetane boost to my tanks. The 1st thing I noticed was easier starts and a much smoother idle. I haul bulk liquids and most of the time I am grossed out at 80,000 lbs. Pulling the hills across central Pennsylvania is a little easier since I started using Power Service products."

"I am absolutely certain that your products have been the central reason for the extended miles and the trouble free operation of my Rabbit."

Dan Willis, Heflin, Alabama
1981 VW Rabbit 1.6 Diesel

"I have driven a VW Rabbit 1.6 diesel for 14 years with zero problems. From the very first time I used your fuel additive, I immediately noticed less smoking and more power especially going up hills. It starts instantly even on the coldest days. I had the engine overhauled at 486,000 miles and now have 53,000 on the new engine. I am absolutely certain that your products have been the central reason for the extended miles and the trouble free operation of my Rabbit. Does anyone even remember the VW Rabbit. Mine is the only one I see on the road. Thanks Power Service"

"You have another convert!"

Jon Aikens, Pembroke, Ontario, Canada
2005 Ford F350 4x4 CC LB Lariat 6.0

"I commute about 340 km (205 miles) per day in my 2003 VW tdi, mostly highway. I have been using an expensive additive imported from Germany that worked great. One day at my local truck stop, I notice they are now carrying Power Service cetane booster - 10 doses for the same price as one from my import. I decided to give it a try based on the recommendation from a long-time VWer who used it in his gravel truck fleet. Wow!! It added more than a little pepper to my little slightly modified diesel - now it truly is a "sooty sports car", minus the soot. You have another convert!"
