Modern engines feature tighter clearances and advanced coatings, requiring lighter synthetic oils like 0W-20 or 5W-30 to minimize friction and maximize fuel economy. Original Equipment Manufacturer (OEM) specifications are found in the owner’s manual and represent the exact balance of protection and efficiency the engineers designed the engine to run with.
Oil Weight Cold Weather Engine Start: Ensuring Easy Winter Starts
The Heat Stability Factor (The Second Number) While the "W" rating addresses cold flow, the number after the dash indicates the oil’s viscosity at 212°F (100°C). The Cold Weather Factor (The "W" Rating) The number preceding the "W" stands for Winter and measures the oil’s cold-start viscosity.
Choosing the correct oil weight is one of the most critical decisions for maintaining engine health and performance. Using the wrong weight in a cold climate can result in hard starting, increased wear, and a shortened engine life because the oil is too gelatinous to lubricate effectively.

Deviating significantly from these recommendations can void warranties and lead to premature failure. This is crucial because oil thickens significantly in low temperatures.
