The winter season places special demands on the performance characteristics of motor oil. Low temperatures significantly affect the oil’s fluidity, the ease of engine start-up, and component wear during the first moments of operation. Choosing the right motor oil for winter helps avoid engine problems and increases reliability. This article outlines the key parameters of winter oil and presents Pexol brand solutions adapted for cold climate use.
How Low Temperatures Affect Oil
At subzero temperatures, oil viscosity increases, making it thicker and harder to circulate through the system. This can reduce lubrication efficiency and increase engine wear at start-up. There’s also a risk of inadequate oil pressure during the first seconds of engine operation.
Understanding SAE Marking and Winter Viscosity
SAE motor oil labeling contains two values: the first indicates winter viscosity (for example, 0W, 5W), and the second shows how the oil behaves at high temperatures (for example, 30, 40):
- The lower the number before the “W” (Winter), the better the oil maintains fluidity in the cold.
- For instance, 0W-30 oil functions at lower temperatures than 5W-30.
Why Oil Fluidity Matters in Winter
Good oil fluidity at low temperatures provides:
- Quick coverage of all friction surfaces in the engine.
- Reduced wear during cold starts.
- Stable oil pressure.
- Improved fuel economy during the first minutes of warm-up.
Using oil with incorrect viscosity can accelerate engine aging.
Pexol Products Recommended for Winter Use
Pexol offers oils with enhanced low-temperature properties. All these products have high oxidative stability and resistance to thickening.

Recommendations for Changing Oil Before Winter
To prepare your vehicle for winter:
- Replace motor oil before the onset of persistent frost.
- Check the oil’s storage date and packaging integrity.
- Ensure the oil meets your engine’s requirements and the region’s climate conditions.
- Replace the oil filter when changing the oil.
Choosing motor oil with winter use in mind is a vital aspect of seasonal vehicle maintenance. Pexol oils possess the necessary characteristics for stable engine performance at low temperatures and provide reliable protection. Timely oil changes and proper product selection help avoid cold start issues and contribute to engine longevity.
