Diesel oils are used in heavy vehicles, such as trucks, buses, and tractors. They are also used in SUVs and cars. Compared to gasoline, diesel oils have several benefits, including:

  • They are more economical
  • They’re safer
  • They’ve higher fuel efficiency
  • Lower emissions
  • Higher mileage

The only problem is that conventional diesel oils’ viscosity levels increase at lower temperatures. This converts them into a non-flowing gel. When this happens, the oil can no longer flow through the fuel lines.

The good thing is that there are synthetic oils that feature anti-gelling agent to keep your engine running in cold environments.

Choosing the Best Diesel Oil

There are several factors you should consider when choosing the best diesel oil. First, you should consider the viscosity grade your manufacturer recommends. This will help you determine the right starting temperatures of your diesel engine. The oil should be able to ensure optimal engine performance even when under pressure.

Cost is also an essential factor, but you shouldn’t go for cheap ones that may not perform well or at all. Also, an expensive oil doesn’t mean it’s high quality. Plan your budget and compare prices of different diesel oils.

Bear in mind that not all oils have the same formulations. You want an option that’s compatible with your engine. This is why you need to pay attention to the viscosity and performance levels of your oil. Be sure to check your manufacturer’s chart of recommended viscosity grades. You should also choose an oil that will clean your engine parts without causing any damage.
