Different oil grades for the Summer and Winter months for Trucks

Choosing the Correct Oil for Your Vehicle: Managing the Seasons

Your truck's engine's happy purring sound is evidence of your concern for and attention to its maintenance requirements. The engine oil you use is among the most important factors that go into achieving this peak performance. Choosing the proper oil can have a significant impact on the longevity and efficiency of your car, especially when it comes to seasonal changes.

Oil Grading Explained

In essence, oil grades are the oil's "thickness" or viscosity, which indicates how easily it flows at particular temperatures. Most of us are accustomed to designations such as 10W-40 or 5W-30. Here's a brief summary:

  • The number before the ‘W’ (which stands for Winter) signifies how the oil will flow when it's cold. Lower numbers mean the oil is thinner and will flow better in colder temperatures.

  • The number after the ‘W’ indicates how thick the oil is at the engine’s regular operating temperature. A higher number means it's thicker, providing better protection when the engine heats up.

Winter vs. Summer: Choosing the Best Option for Trucks


The engine heats up more quickly in the summer and requires oil that can withstand higher temperatures. For trucks in the summer, thicker oils like 10W-40 or 20W-50 are frequently advised. They will offer the required resistance to abrasion and won't thin out too soon.


Oil that runs smoothly even in below-freezing temperatures is necessary during the winter months. In general, thinner oils—like 5W-30 or 10W-30—are better for use in trucks during the winter. Even in below-freezing temperatures, the engine will remain adequately lubricated thanks to these oils.

Checking Engine Oil in Winter

Winter engine oil checks can be a little challenging, mostly because the lower temperatures can change the properties of the oil. Here's a detailed how-to:

Park in a level area

Make sure your truck is parked level every time. This guarantees that the reading on the dipstick will be accurate.

Heat It Up a Little

Give your truck a few minutes to run after starting it. This facilitates improved oil flow and helps the oil warm up slightly.

Switch Off & Watch

After the engine has warmed up, turn it off and give it a few minutes. This allows the oil to stabilize.

Dipper Time

Take out the dipstick, clean it, and put it back in. Take it out once more and check the level now. It ought to fall between the lowest and highest possible score.

Verify the Clarity

There should be no milky look, no graininess, and the oil should be clear. If it's murky, there may be moisture or pollutants present. It's time to make a change!
