Frequently Asked Questions
Q. Will using the Syntek Xtreme Fuel Treatment / Engine Boost 2.0 void the engine manufacturer’s warranty?
A. No, Engine manufactures cannot discriminate against the use of a fuel additive. Under the terms of the Magnuson-Moss Warranty act, engine manufacturers must take the position that the use of a fuel additive does NOT void the engine warranty unless it can be proven that the specific additive was the cause of the failure. Manufactures may assert that the use of certain additives may prove useful.
Q. What makes Syntek Xtreme Fuel Treatment / Engine Boost 2.0 different from all the other additives on the market?
A. Syntek Xtreme Fuel Treatment / Engine Boost 2.0 is a proven fuel treatment, used in the mining industry for the last 11 years. It is very concentrated; one gallon will treat 10,000 gallons of fuel. Not only does it have a combustion catalyst that will help increase fuel economy, Syntek Engine Boost 2.0 also has detergents, to remove harmful deposits from fuel pumps and injectors, lubricants to provide lubrication to pistons, fuel pumps, injectors and reduces friction, fuel stabilizers to prolong the life of stored fuel, polymerization retardant and dispersants to reduce sludge in fuel, rust and corrosion inhibitors to prevent fuel system corrosion and demulsifiers to help reduce water that forms in fuel.
Q. Can I use lower grades of fuel when using Syntek Xtreme Fuel Treatment / Engine Boost 2.0?
A. The Syntek Xtreme Fuel Treatment / Engine Boost 2.0 formula allows you to use the lowest octane fuel without causing pings or lower engine performance.
Q. Can I use the instrument panel in my vehicle that shows ‘miles to empty’ and MPG as a true measurement?
A. Most computers in today’s cars and trucks show an average of savings and can be calculated in a number of different ways. It is advised, before using Syntek Engine Boost 2.0, to get a true MPG base line, by dividing the number of miles traveled by the gallons of fuel used. Then, once the additive is used, revaluate the savings by the same method. If you pull a boat or trailer you may have to remove the positive battery connection to reset the computer to get an accurate reading on your instrument panel.

Personal Success Stories
Since my first use of Syntek Engine Boost 2.0, I have been getting an extra 60 miles per tank! Syntek Engine Boost is saving my wife and I over $10.00 with every fill up. I would recommend using the Engine Boost to anyone.

I have been using the Syntek fuel additive in my 1999 Dodge D350 truck in the last three tanks of fuel. The fuel mileage has increased by 2 mpg and the performance has also improved. I would highly recommend this product to anyone who is fuel conscious and wants to increase performance of the vehicle.
Tony G. / Idaho Falls, ID
I have a 1991 Honda Accord sedan with 300,000 miles on the odometer. I am a traveling sales guy living in Los Angeles. I think this car has one of world’s most efficient engines. I take very good of the car; using only 89 Octane gasoline and maintain the engine religiously. Over the past 100K miles, I began to notice a dropping in MPG from 28-32 MPG down to 22-24 MPG. I have since used three half oz treatments of Syntek. I am amazed to report that I am back at 26-28 MPG. Again, I have not altered any driving pattern. Like everyone in LA, I am stuck in traffic half of the time while I am in the car. I am not a scientist, but I do keep a detailed record on all of the gasoline purchased and the mileage. I am saving over 12% on my MPG and another .10 cents per gallon at the pump because I now can use 87 Octane with the same results as 89. This is an amazing product!

I have been driving a Trailblazer for over 4 years and never once has my mileage gone over 300 miles per tank. After using Syntek Engine Boost my mileage jumped up to 365 per tank. I have even gotten up to as high as 445 miles per tank on the highway. This increase in mileage and the ability to use the lower priced octane saves me an average of $13.00 per fill up. I got my family and friends to also use Syntek and they are experiencing similar results.

Since using the Syntek product we have not had any failures in injector pumps or injectors. We use generators in pre-Olympic events and TV sporting events. In the 2002 Winter Olympics we were using 875 gallons of diesel fuel per day and after using the Syntek product our fuel consumption dropped to 675 gallons of fuel per day. We have had generators come to us form other parts of the country that were not running real well. We added a double dose of the Syntek product and within several hours the generators began running smoother. This is a great product that I recommend to everyone.

Using Syntek Engine Boost has lowered our fuel consumption greatly, in fact, by 15% per year – a significant savings. My biggest savings, that was unexpected, came in the form of labor costs. Buses get extremely black on the rear door from diesel residue. To remove the black, we were spending $14.50 per week per bus for cleaning ($7.25 per hour per driver times 2 washes per week) or approximately $106,000.00 per year. Since using Syntek Engine Boost, we only need to wash the buses once every other month. This has created a saving in excess of $95,000.00 per year.

We decided to do a test on the fuel consumption between the trucking side and construction side of our company. The test result using Syntek were shocking, doing the same amount of work load if not more, we purchased 15% less fuel than the previous months. Our trucks were topping the “Three Sisters” hills on I-80 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.
