Practical Buying Advice:

Choosing the right oil depends on your vehicle’s requirements (check your owner’s manual). Synthetic oils generally offer better protection and fuel efficiency than conventional oils, but they cost more. Consider the following:

• Vehicle type: Car, truck, motorcycle, lawnmower, etc., each require different oil types.
• Oil viscosity: The recommended viscosity is crucial for proper engine lubrication and performance. Refer to your owner’s manual for the correct viscosity grade.
• Budget: Synthetic oils are more expensive but may offer better fuel economy and engine protection in the long run.

FAQ:
