Choosing the Right Mobil 1 Dexos Oil for Your Vehicle
Selecting the correct Mobil 1 Dexos oil isn’t complicated, but it requires attention to detail. Using the wrong oil can negate its benefits and potentially harm your engine.
Deciphering Viscosity Grades (0W-20, 5W-30)
The numbers on an oil bottle, like “0W-20” or “5W-30,” refer to its viscosity. This is a measure of its resistance to flow.
-
The “W” stands for winter. The number before the “W” (e.g., 0W) indicates the oil’s viscosity at cold temperatures. A lower number means better cold-weather flow, which is crucial for quick lubrication at startup.
-
The second number (e.g., 20 or 30) indicates the oil’s viscosity at operating temperature. A higher number means thicker oil at engine operating temperature, providing a stronger protective film.
Modern engines, particularly those designed for fuel efficiency, often specify lower viscosity oils like 0W-20 or 5W-30. Always adhere to your manufacturer’s recommendation.
Checking Your Owner’s Manual: The First Step
This is the most critical piece of advice for anyone wondering how to mobil 1 dexos oil selection correctly. Your vehicle’s owner’s manual is the definitive source for the exact oil type, viscosity, and Dexos specification required. It will clearly state:
-
The specific Dexos standard (e.g., Dexos1 Gen3, Dexos2).
-
The recommended viscosity grade (e.g., 0W-20, 5W-30).
-
The oil capacity for an oil change with and without a filter change.
Never guess or rely on general advice; the manual provides tailored information for your specific engine.
