oil for 1994 Mazda 626 189000 miles

Recommended Posts

I wouldn't worry. 10W-30 is the recommended viscosity for warmer climates, there shouldn't be any mechanical damage when using 5W-30. As long as both viscosity reaches "30" by operating temp, no harm is done. The W stands for weight and is a reference to only when you're cold starting your car up. The lower that number is, the easier for the flow of oil through your engine parts.


Hope that answers your question.
