Gas Additive
Fuel Mate Plus® and 4-Power® G are gas additives designed to clean your engines and keep them clean.

You can find these two products below.

Fuel Mate Plus® is a money saver over the long haul. The following testimonial from a current customer is a typical response to this product when used as recommended.
“Conklin Products and Fuel Mate Plus improved the mileage on my Ford Explorer. My 2003 Ford Explorer sport truck has 134,000 miles on it and was getting 12 mpg…
in the city and 17 mpg on the highway. After adding Conklin’s Fuel Mate to the tank for the second time with a fresh oil change, my truck’s mileage jumped to 16 mpg city and 20 mpg highway. Now, even though my truck needs an oil change, it’s still getting 16 mpg city and 20 mpg highway” – Glenn B., Maple Park, IL
Fuel Mate Plus® provides daily protection from performance-robbing buildup of deposits and debris, and extends injector, spark plug, and fuel pump life. We stress using this product as recommended in order to achieve the results that it’s designed for. Products in this category must be used regularly to actually clean your engine. You should be skeptical of any brand that claims otherwise! Only an overly harsh product can clean your engine with a single treatment. Such products will eventually cause damages throughout your fuel system.
Fuel Mate Plus® also stabilizes fuel and inhibits fuel varnishing during off-season storage of vehicles, motorcycles, snowmobiles, and watercraft.
Conklin has been in the business of engineering superior automotive products for many decades with the customer in mind. Their mindset of engineering a quality product that always gives the end-user the best deal never fails.

How to clean your fuel system with 4-Power® G
Add 4-Power® G when filling the gas tank. First-time users should add 4-Power® G to two consecutive tanks of fuel. After the second tank, if the vehicle is equipped with a fuel filter, it should be changed. Then, treat one tank of fuel with 4-Power® G every 4,000 miles or every 4 months.
