Get the Most from Your Diesel Engine

Tractor in a barn

The scent of diesel exhaust on a clear, crisp morning may remind some of the Big City, where buses and delivery trucks are ever-present. But country living comes with its own share of diesel fumes, thanks to farm tractors, pickups, and big diesel-powered trucks used for hauling grain or manure. City or country, diesel engines are efficient, both in terms of fuel economy and power generated. But like any other mechanical device, diesel engines require some TLC, and perhaps even some modifications to perform at their best. Here are a few tips for getting the most out of your diesel engine.

Glow plugs

Glow plugs heat the combustion chambers in a diesel engine, making cold-weather or even cool-morning starts easier. A diesel engine has a glow plug for every cylinder, so if one goes bad you may not notice right away. You’ll know it’s time to replace them if you’re having trouble with cold starts, or if it sounds like the engine isn’t firing on all cylinders.

Engine heater

Engine heaters are helpful tools for diesel owners once temperatures plummet. If you’ve seen diesel-powered trucks or school buses parked overnight with what appears to be an electric cord sticking out the front, it’s probably for the heater. There are several varieties of engine heaters out there. You can use an electric heater that attaches to the oil pan via a powerful magnet. This prevents the oil from thickening and causing hard starts. There are also heaters that insert into the oil dipstick tube, diesel fuel heaters to prevent gelling, and circulation tank heaters that keep the engine’s coolant warm. All of these devices make easier starts possible in low temperatures.

Diesel engine programmers

With the advent of computer-controlled diesel engines comes the increasing popularity of diesel engine programmers. Frequently used for diesel-powered trucks, these programmers enable users to change the engine’s factory-programmed settings in order to increase horsepower and fuel efficiency. There are a variety of options out there , depending on your vehicle make and model.

Diesel fuel additive

Another consideration, even for diesel-engine cars, is a diesel fuel additive. Many are approved for use in all diesel fuels, and have a wide range of benefits, including:

  • Preventing fuel from gelling in cold temperatures
  • Keeping injectors clean
  • Providing lubricants that protect the engine
  • Boosting cetane (a measurement of combustion quality) for faster cold-weather starts

These are just a few considerations that can improve your diesel engine’s performance and efficiency.
