Gas vs. Diesel

Gas or Diesel: Which Engine is better for Your Truck?

Customers often ask about the cost effectiveness of a Cummins Turbo Diesel versus a Hemi Gas V8. While many factors exist that may dictate which engine to choose, such as towing and payload, there are advantages to both. 

It is generally accepted that diesel engines are more fuel efficient than gas engines. According to the U.S. Department ofEnergy, diesel powered vehicles can go 20% to 30% more on a gallon than gas engines. Even customers have reported receiving an average of 4 to 5 miles more per gallon with a diesel engine than a gas powered truck.

Not only is a diesel vehicle more fuel efficient, but new technologies have made diesel engines:

  • More powerful
  • Accelerate faster
  • Cleaner

However, diesel engines cost significantly more than a gas engine, which makes cost of operation a key buying factor. Although the RAM's 6.7L Cummins Turbo Diesel is often a clear choice for many commercial truck customers, consider the following scenario.

There are many other factors such as towing, maintenance, vehicle pay load, weather that affect fuel economy and operation costs, but the following example is based strictly on estimated miles per gallon (MPG) and fuel consumption.

Example:

 EngineCost Per Gallon   MSRP Annual Miles Gallons/YearCost of Gas/Year 
 Gas (10 MPG)$3.85$25,66015,0001,500$5,775 
 Diesel (14 MPG) $3.95 $36,665 15,000 1,071$4,232 
 Difference $0.10$11,005 429 $1,543 
 

Difference in Cost / Difference in Annual Cost of Gas = Break Even Point

$11,005 / $1,543 = 7.13 years

This means that you must own your diesel truck for more than 7.13 years before it becomes more cost effective than a gas powered truck. If you plan on keeping your truck long term, it's better to buy diesel but if it's a short term purchase, you're better off with a gas truck.
