GO 15™ Testimonials

Mr. Don Gray, a heavy truck sales and service manager with Caterpillar with over 25 years
experience in his industry, documented the results of his experience with Engineous GO 15™ in
his 1995 Ford Explorer. Mr. Gray experienced an overall 22% increase in MPG while pulling a
heavy load using 87-Octane fuel.

“I would recommend Engineous GO 15™ to every consumer and especially to the large truck users as a way to improve profits through improved fuel mileage and less wear and tear”.

Dr. Aiden O’Rourke M.D. achieved similar results in his 1995 Cadillac STS Seville. His
average day-to-day MPG in the first two years of ownership was 13.8 to 13.9 MPG. After his
initial treatment of Engineous GO 15™ his mileage increased to 16.6 MPG. Since retreating his
engine Dr. O’Rourke has experienced a consistent 17.2 MPG, an overall increase of 24.6%.

“I was so impressed by the results, I purchased the rights to the product and I started the company Engineous. To date, GO 15™ is the most economical method to decrease
emissions and increase fuel economy”.

"Don Hearn & Sons Inc., a large trucking firm agreed to Controlled study of GO 15™ and had this to say about the results of this study."

"As confirmed by neutral laboratory testing, our trucks averaged an increase of 17.5% in fuel efficiency and, additionally, the engine wear was reduced by at least 50%.

Thank you for giving Don Hearn & Sons the opportunity to participate in the evaluation of your product. When Go15 goes to market, Don Hearn & Sons would certainly purchase this product for continuous use in our fleet."

DHC Construction Services of Dunedin Florida had the following to say about their heavy
equipment:

“We agreed to treat our whole fleet of trucks and equipment with the Engineous oil treatment GO 15™. Since then we have shown a 21% decrease in fuel amounts burned. One of our roll-off trucks ran low on water and got extremely hot before the driver saw it. It should have ruined the motor but we are happy to report that there was no damage and that was 2 months ago.

I have personally given the product to eight of my friends and they all have seen the improvement in their applications from boats to Jeeps. You can be proud of your product because it does what you claim it would do and more”.

Mr. Fred O. Brenner Sr. the Mayor of the City of Winchester Missouri, a suburb of St. Louis
has repeatedly treated his 1999 Chevy Blazer with GO 15™ since May of 2004 and had this to say.

“I have been driving SUV’s for 15 or more years and have used a number of motor oil additives, but nothing compares to Engineous GO 15™. The 1999 Blazer I have now with 60,000 miles on it now performs better than when it was brand new with 10 miles on the speedometer. It starts easier in sub-zero temperatures and runs cooler in hot weather 90 degrees and above.

My mileage has increased per gallon of gas in the city and on the highway. the increase is in the range of 19 to 20 percent”.

We recently got this testimonial from Ryan Richardson President of Car Cannibal, LLC

“I have an ’05 Dodge 3500 crew cab 4wd w/ 6 speed transmission and 110K miles. When I first introduced the product in July of ‘06 my baseline was 18.5 MPG under normal driving conditions. At around 4700 miles or 1700 miles into my second oil change w/ the product I saw my first real increase to 19.6.

My test was interrupted with 2 heavy long distance loads but when I resumed normal driving again at about 7000 miles my mileage had improved to 21.2 or 13%. My cylinder head temperature has also decreased slightly from 192 to around 182. Very impressed and my MPG has stayed consistent as of January 9, 2007”.

We received this letter from Keith Skousen of Lehi, Utah dated April 21, 2007.

"I am enclosing a check for Sixty-six and 80/100 dollars. It is for four bottles of 8 ounce GO 15™.... The last four bottles that I have ordered has been a great gasoline saver in my 1997 Protege Mazda... My mileage went up from 20 miles per gallon to 30. My four wheel drive 1995 Suburu didn't do quite as well.. The mileage went from 17 miles to the gallon to 23... Keep up the good work.... "

We received this letter from Bob Hudspeth of Denver, NC in December 2008

I was pretty skeptical whether this product would really work, but I thought I would try it. I have a 2003 Buick that was getting 16 mpg. I started using GO-15 and my mileage went from 17 mpg to 21 mpg. That is a 3 mpg improvement. I am very impressed and, with the current gas prices, I am happy I found GO-15!" It's a whopping 23.5% improvement!!! and GO-15 is definitely a keeper.

This letter came from Glenn Maze of Charlotte, NC in January 2009

We decided to do a test on the fuel consumption between the trucking side and construction side of our company. The test results using GO-15 were shocking. Having the same work load if not more, we purchased 15% less fuel than the previous months. Our trucks were running from Charlotte to Wytheville on I-77 with 2 more gears than ever before and the trucks went from 5.6 miles per gallon to 7.2 miles per gallon after just one month.
