Bus & Heavy Duty Testimonials

From Saratoga Springs City Schools:

We just wanted to take a few minutes to express our thanks for such a wonderful product. The K100 additive has been used in this fleet for approximately 4-1/2 years. In that time we’ve had zero (0) fuel related breakdowns or mechanical failures. We purchase approximately 150,000 gallons of fuel a year and this year by careful blending and the use of K100, we saved the district approximately $36,000

This was made possible by not cutting our fuel any more than 20% kerosene. As all folks, we were concerned going to ultra-low sulfur fuels, but it has been a trouble-free transition because of K100 products.

From Birni Bus Service, Inc.:

We have been using the K100 product year-round for just over three years and have had great success. Since using this product we have noticed increases in fuel mileage, and a decrease in smoke during idle. This product has also cut our gelling to virtually no gelling. This is a great product and has saved our company a great amount of money both on the up-keep and mpg of our buses. I would highly recommend this product to anyone looking to run more efficiently.

From Niagara Falls Coach Lines, Inc.:

Just thought we would drop you a line to let you know how satisfied we are with K100-D and K100-G. There has been noticeably less black smoke from our fleet of sixty diesel buses, along with less smell from the exhaust at idle, no water problems (sinter and summer), no gelling in winter, better starting, better power when running and even better fuel mileage. Thank you for a product which has been a great asset to our business.

From Thousand Islands Central School District:

We have been using K100-D diesel fuel additive since August… we have seen an increase in mileage of 1 to 1.3 miles per gallon. We also have seen our busses run smoother with less smoke at start-ups.

From Freeman Bus Corporation:

I would like to take this opportunity to inform you of my satisfaction with your product. Initially, out of concern for my fleet operations, I was somewhat hesitant to use the product due to the gelling characteristics of #2 diesel fuel (LSD, 500ppm sulfur). I decided to try using K100-D with straight #2 LSD and am happy to report that I experienced no gelling. I’ve also witnessed an increase in mileage, by up to 1mpg. This product has saved me the cost of kerosene, and my engines burn cleaner. Thanks for a great product.

From The Vending Center, Inc.:

I met Phil Mansfield, about 4 years ago, it was my misfortune to draw him as a partner in a FLW Bass Tournament. I guess because I am a gluten for punishment, he and I have become good friends and have shared expenses for tournaments with a couple of other friends for the last few years.

Shortly after meeting Phil, he began his sales pitch of K-100 a fuel additive; he said it would increase the mpg and life of the engines in our company fleet of about 8 F350 Diesel Trucks. Well, I was very skeptical but to shut him up I bought 10 gallons and it really works. My best guess is about a 10% increase in MPG. As far as longevity of the engines, only time will tell but it does seem we are having less problems with our troublesome 6.0 Ford Diesel (known no to be the best Diesel Engine) it really appears that injector replacements are not as common in the engine as they were prior to using K-100 additive.

For me personally, I drive a F-250 6.0 Diesel, I am seeing a 12% increase in MPG when not towing a boat and about 9% increase in towing MPG by using the K-100 additive.
It really gripes me to say this: But Phil thanks for your persistence on me trying K-100 additive, it pays for itself in increased MPG and it appears maintenance cost is down also. Time will tell more about the longevity of engine life, but we have several 6.0 Diesels with over 300,000 miles still running good. Officially, I think the K-100 is a great investment.
