Road Ready Episode 11: Driving for Maximum Fuel Efficiency

by Moses Ludel
America is still dependent on fossil fuel. The number one way to save fuel is to drive for fuel efficiency. Driving techniques can save fuel and also reduce load on the engine. For your gasoline or diesel powered vehicles, this will save fuel and money.

The secret to saving fuel is driving technique, and the way you drive will determine the actual fuel mileage. In Episode 11 of Road Ready, the focus is maximizing fuel efficiency from the driver’s seat. Whether you drive commercially, commute to work on freeways or drive a recreational 4×4, the tips shared apply to any gasoline or diesel engine.

When stone stock, our Ram/Cummins 3500 4WD Quad-Cab delivered as much as 25 mpg. Even with a chassis lift, oversized tires, axle ratio changes and 800 pounds of accessories and auxiliary fuel, we can still achieve 20-plus miles per gallon on a flat highway cruise. The XJ Cherokee 4×4, lifted and accessorized, still musters 15 miles per gallon on the highway with 191,000 miles on the engine.

Torque peak is the key to fuel efficiency with any diesel or gasoline engine. Top mileage means driving within the peak torque range. For this reason, diesel engines are hypersensitive to rpm. Stone stock, the Ram could squeeze 17 mpg pulling the car hauling trailer with the Cherokee 4×4 on board. Towing is now in the 12-14 mpg range due to the change in aerodynamics, chassis modifications, software tune and vehicle weight.

Before the chassis lift, oversized tire, gearing change, added auxiliary fuel tank and list of accessories, our stone stock Ram-Cummins truck achieved a best ever 25 mpg when driven strictly for maximum fuel mileage. The stock truck consistently got 22-24 mpg on the highway. It’s all about driving technique and utilizing the engine’s peak torque.

Mobil (“Mobilgas”) Economy Run techniques are just as useful today as in the day. Drivers with savvy maximized every drop of energy in a gallon of gasoline. You can, too!
This Stewart-Warner gauge was popular in the postwar era and sixties. Revived among Rat Rod builders, the “Motor Minder” is useful for any gasoline engine. Vacuum readings indicate maximum engine and fuel efficiency. Driving by this gauge can help save fuel.

The only way to maximize fuel efficiency with a gasoline or diesel engine is by driving sensibly and understanding the engine’s peak efficiency points. Episode 11 of “Road Ready!” shares details about the Motor Minder and other ways to save fuel. With fuel prices soaring, these techniques can help keep a lid on your monthly fuel bill.
