Changing the Way You Treat Your Fuel

Our Users say:

Hey…Thanks for a great product. I purchased a bottle of you Gas Plus from a Farm Supply/ Convenience store while on a 8000 mile cross country motorcycle trip. We ride a 2005 Honda Goldwing 1800 trike pulling an Aspen camping trailer gross weight of about 500lbs. The fuel economy prior to using GasPlus was less than 25mpg. While using GasPlus up to around 32mpg…works great. I need to get some more of this product.

I started using PFS on a recommendation from a farm buddy. I started with my 2015 F-150. My fuel mileage went from a consistent 12.6 to 12.8. Now I maintain a 14.6 average. I then used it in my 2001 -115 horsepower Mercury, GPS speed went from a consistent 37 to 38 mph to 41 to 43 mph. I haven’t been able to get over 38 in five years. I now add PFS to everything. I add it to my mower, splitter, generator and my 850 Outlander. Everything starts right Now and less maintenance on everything. Thank you fuel guys. PS, thanks for being on the other end of the phone when I placed my order.

I have used your additive in my duramax and love it!

We ordered their Gas Plus fuel treatment for our 98 Dodge Durango. It is amazing!!! Increased fuel economy (which in an older V8 is a must), drives smoother, more power!!! And when we got the shipment in, they sent us a little notebook, sticky notes, and a really nice pen with stylus and flashlight on the end. Love the customer service!!! Love the products!!!

Will definitely be ordering from them again!!! You have to check these guys out!!!

PFS additives are highly concentrated for added value and quality. This also dramatically reduces the amount of plastic waste in consideration of the environment.

Performance Fuel Specialists Profile:

Performance Fuel Specialists fuel treatments were brought to market in 1985, initially only available for industrial, transportation and bulk fuel application.

In 1990, PFS worked in cooperation with a chain of parts stores to introduce a line of fuel treatments for the retail market.   The hardest part of the retail application was the packaging. The retail product is virtually identical to the industrial version. PFS has also brought to the retail market the same ideology of the industrial market that is changing the way the retail market looks at additives. PFS products are only distributed through qualified distributors and parts stores.

We believe this is extremely important in order to keep the integrity that PFS has tried so hard to attain. We do not sell to discount stores of any kind and certain criteria is expected to be met by those wishing to distribute our products.

PFS is dedicated to providing information to educate those selling, using or interested in fuels and additives. We follow a wide range of areas from the changing regulations, to fuels of the future.

PFS is also dedicated to providing the best fuel treatments on the market today. In line with our devotion to proper fuel maintenance we now have a line of fuel testing tools designed to aid those interested in a careful and adequate fuel maintenance program.
