* 10W-30: This is a common grade for older vehicles and generally works well in moderate climates. The "10W" indicates its viscosity in colder temperatures, and the "30" represents its viscosity at higher temperatures.
Important Considerations:
* Owner's Manual: The best place to start is your owner's manual. It will have the manufacturer's recommended oil type and viscosity.
* Climate: If you live in a very hot climate, you might consider a higher viscosity oil (like 20W-40 or 20W-50). In very cold climates, a lower viscosity oil (like 5W-30) might be better.
* Oil Type: While conventional oil is fine, you could consider using high-mileage oil if your engine has significant miles. Synthetic blends or full synthetic oils offer better protection and longevity, but are more expensive.
* Engine Condition: If your engine is worn, a higher viscosity oil might help with leaks, but this isn't a long-term solution. Address any underlying engine problems.
Recommendation: Check your owner's manual first. If you can't find it, start with 10W-30 conventional oil. If you have concerns or questions, consult a trusted mechanic.
