I’ve always viewed fuel additives for boats – other than those offered by the outboard companies – with a jaundiced eye. Some are definitely not good for outboards. But for the last year now, I’ve been using an additive called PRI-G (it’s new for recreational boats but has been used commercially for many years). PRI-G has many benefits for marine gasoline engines.

Most important, it stabilizes fuel for at least two years – even in the carburetor, which makes it unnecessary to run the carb dry if the engine won’t be used for up to a year. It also reduces cylinder head combustion temperatures as well as inhibits both carbon buildup and corrosion. And it helps keep the fuel system clean, while reducing harmful emissions. It has even been successfully used to restore gasoline that is several years old. – Bob Stearns, "Fuel Foul-Ups", Field & Stream September 2000 issue

"This (PRI) product that prevents fuel rot is literally an industrial strength solution, with nearly the same formula used in ocean going vessels that burn heavy fuel oil. Another benefit of PRI is the way it freshens old fuel that has gone bad years ago. The good news gets even better. In addition to protecting fuel from the ravages of time, PRI-G also minimizes carbon deposits in the combustion chamber. While this is aimed at carbureted two-stroke outboard, the carbon-busting feature is also valuable on injected outboard motors and four-stroke outboards, inboards and stern drives." - Tim Banse - Motor Boat & Sailing, June 1999

"GENERAC Power Systems inc. has reviewed PRI-G gasoline treatment, and supports the benefits and improved performance claims you literature points out. The fuel stabilization to extend fuel storage life is impressive. It is apparent that carbon deposits can be significantly reduced to the point of being a non-factor. Power Research Inc.certainly can be a major factor in the engine and generator industries."  Steve Hespe, Vice President - Service Operations, GENERAC, Waukesha, WI

As a manufacturer and direct distributor of Ford Marine Engines, we highly recommend the use of Power Research Inc. fuel treatment products to all of our customers.

PRI has established an impressive track record in reducing emissions products from both gasoline and diesel engines while providing improvements in performance and economy. Additionally, PRI treatments are unsurpassed in preserving fuel quality in storage, while preventing hard carbon deposits on critical engine components. In summary, Power Research Inc., is on the cutting edge of preserving and enhancing fuel quality for the consumer. -- Chris Stout, Technical Support, Ford Marine Power Products

"As a competitive and winning tournament sport fishing team, we depend on fast starts, reliable service and performance plus.  At these tournaments, the boats are at idle a lot.  Our competitors look at us and wonder why our engine doesn't carbon up - while their engines are being choked with carbon, slowing them down for frequent engine cleaning.. PRI-G is our secret weapon. It's a remarkable product. As a NASA specialist at Cape Canaveral, I'm very picky about what I put in my fuel, and I have researched this extensively. PRI-G  incorporates the most advanced fuel treatment technologies available. PRI simply has no equal. That's why PRI is the choice of  everybody here at NASA who boats."
Johnny Gay, Team Freespool, Port Canaveral, Fla.

"We have four retail stores covering South Florida. People really like PRI products and I can't keep them on the shelf. Today they are far and above our leading selling brand for diesel and gasoline treatments. I use PRI-G and find that it really does the job. I especially like the fact that PRI has a strong history in commercial maritime.

  I urge retailers to carry PRI. You'll be doing your customers a great service, and you'll also make excellent sales volume for the fuel treatment category."
Dave Shields - Store Manager, Hopkins-Carter, Fort Lauderdale, Florida

"As a diesel fuel supplier and marketer of petroleum products to South Florida recreational and commercial marine users, our objective is to offer the very best products and services available. For this reason, we picked up the PRI line two years ago.
  We have not been disappointed. Although many of my clients were using products we formerly carried - Valv-Tec and Biobor® -   they quickly discovered that PRI was superior in all respects. Not only do we get strong repeat business, we get new PRI clients everyday. I strongly urge any marine retail marketer to make the switch to PRI."

  "I've tried many additives over the years, but after running my boat (with a 200 hp Mercury) in La Paz with PRI-G for gasoline, I couldn't believe the difference in the performance of my outboard. This product is incredible!"
