Here's why:
* Year and Engine: The correct oil weight depends on the specific year of your CLK320 and the type of engine it has (e.g., M112, M113). Different engines have different specifications.
* Climate: The climate where you live also plays a role. Thicker oil is better for cold climates, while thinner oil is better for hot climates.
* Driving Style: If you drive aggressively or frequently tow heavy loads, you may need a heavier weight oil.
What you should do:
1. Check your owner's manual: This is the most reliable source for information about the recommended oil weight for your specific vehicle.
2. Consult a Mercedes-Benz dealership: They can provide you with the most up-to-date information on the correct oil weight for your car.
3. Use a reputable oil change service: Ask them to check your owner's manual and use the recommended oil weight.
Remember: Using the wrong weight oil can damage your engine. It's always best to err on the side of caution and use the oil weight specified by Mercedes-Benz.
