Fuel Economy

L.A. Perks Petroleum Specialists of Nevada specializes in petroleum systems, construction and fuel services. Established in 1974, the company, which also does commercial and residential work, has a service area that covers the entire Western states region, but primarily operates in Nevada and California.

Perks Petroleum Specialists owns and operates 23 vehicles, 12 of which are diesel-powered pickups and service trucks. The fleet is serviced by outside maintenance shops.

All of the vehicles are assigned to specific drivers, says Kylen Perks, the company’s project manager and treasurer, because drivers tend to take better care of “their” equipment. The fleet’s annual mileage exceeds 500,000 miles.

Perks grandfather, LeRoy A. Perks Sr., founded the company which is now owned and operated by Kylen’s father, LeRoy Perks Jr.

With the cost of fuel a major operating expense, and seeking more ways to be a good neighbor, the company began researching ways to better manage fuel consumption and reduce vehicle emissions. It decided to give GDiesel fuel a try in its diesel-powered vehicles. 

With the company’s involvement in the petroleum field, it was able to research GDiesel and evaluate its use for the company’s diesel-powered vehicles. “Using GDiesel made sense and seemed a natural choice for our fleet,” Kylen Perks says.



GDiesel is produced by Sparks, NV-based Advanced Refining Concepts (ARC), a company that develops and manufactures fuels that produce cleaner emissions and more efficient combustion. 

ARC’s inaugural product, GDiesel, uses the company’s zero-emissions ClearRefining process to create a cleaner burning fuel product that requires no modifications to engines or vehicles for use, or to fuel dispensing equipment or storage tanks, says Peter Gunnerman. He and father, Dr. Rudolf Gunnerman, founded Advanced Refining Concepts in early 2008. 

Because GDiesel meets ASTM (American Society for Testing and Materials) D-975 standards for diesel fuel, it complies with all diesel engine warranties.

Advanced Refining Concepts’ proprietary ClearRefining process efficiently refines petroleum with methane derived from natural gas or renewable waste biogas sources, Gunnerman explains. This process is a new closed-loop, low pressure catalytic process that allows refining of liquids below the boiling point.

The resulting product, GDiesel, demonstrates cleaner emissions and more efficient combustion for improvements in fuel economy, and is available at about the same price as conventional diesel fuel, he says.

ClearRefining is unique in that the entire system can be run efficiently off of the electric grid which makes this the first zero emission refining process, notes Gunnerman. 

The Gunnerman family is responsible for bringing five patented clean technologies to world markets in the past four decades, including wood pellet fuel, emulsified fuels and ultrasonic upgrading of petroleum products, among others. The family established ARC to further develop and market its ClearRefining technology.   



One of the selling points in switching to GDiesel was not having to make modifications to company vehicles, says Perks. Another was the fuel’s designation by the Nevada Division of Environmental Protection (NDEP) as an alternative fuel in Nevada’s Alternative Fueled Vehicles in Fleets program.

The NDEP designation allows government fleet operators in Nevada to consider GDiesel as part of their fuel strategy. Nevada requires all government fleets in the two most populace counties, Wahsoe (Reno) and Clark (Las Vegas), to run on alternative fuels.

Another reason for the change to GDiesel was that the infrastructure for obtaining GDiesel was already in place in the Nevada area, so finding the fuel was not an issue, Perks says. The fuel is currently sold by various fuel distributors, retail fueling stations and truck stops. 

L.A. Perks Petroleum Specialists has its own aboveground fueling system for GDiesel at its facility in Sparks.

The GDiesel fueling infrastructure is being expanded as ARC ups its production capabilities, says Gunnerman. Should GDiesel not be available, regular diesel fuel can be used because it is compatible with traditional fuel products.

 “One of the attractive features about GDiesel,” Perks adds, is that vehicles can run on pure GDiesel, No. 2 diesel or a blend of the two. So when you are traveling out of the area, there are no worries when it comes to finding fuel.”

By switching to GDiesel for its vehicles, L.A. Perks Petroleum Specialists didn’t have to invest in new vehicles or component and systems add-ons to gain fuel efficiency and emissions reduction benefits. No extra vehicle maintenance or servicing is needed, and there are no additional training requirements or duties for its drivers.

“Companywide, everyone is happy with the performance of GDiesel,” says Perks. “There have been noticeable mileage improvements and power increases. Once someone tries this product it will be hard for them to return to regular diesel.”
