Diesel engines require a warmup period. This allows the glow plugs time to generate enough heat to help the fuel auto-ignite.
In diesel engines, the fuel must auto-ignite for the engine to turn over. In other words, diesel engines require auto-ignition, whereas gasoline engines try to avoid it.
For auto-ignition to occur, the diesel must be heated to a certain temperature by the glow plugs. Once the temperature of the fuel reaches a certain threshold, the engine can auto-ignite, and thus turn over.
Automotive diesel engines are used to power cars, trucks and construction equipment, as well as stationary engines for pumps and compressors. Larger diesel engines require heavier fuel.
How Do You Know What Type of Fuel to Use in Your Car?
You can easily find the answer in your vehicle’s owner’s manual. Every model has its own characteristics, including fuel specifications.
If you buy a new or used car directly from a dealership, the sales staff should be able to tell you what type of fuel to use. This information is provided by the manufacturer.
If you buy a car from a private seller, they should tell you this information. If you want to double-check, you can always call the manufacturer directly and speak with a customer service agent. Moreover, you can consult the manufacturer’s website or contact a reputable dealer that sells the same car model.
To choose the right type of fuel for your vehicle, always refer to your manufacturer's manual and do your research to stay up to date on the latest changes.
