Important Considerations:
* Owner's Manual: The owner's manual will specify the recommended oil viscosity (like 5W-30 or 10W-30) and the type of oil (conventional, synthetic blend, or full synthetic). This is the most reliable source of information.
* Climate: In colder climates, a lower viscosity oil (like 5W-30) is better for easier starting. In hotter climates, a slightly higher viscosity oil (like 10W-30) may be preferred.
* Engine Size: Different engines might have slightly different recommendations. The owner's manual will specify this.
Using the wrong oil grade can harm your engine, so always refer to your owner's manual for the correct specifications.
