- Price vs. Performance: While synthetic blends are more affordable than full synthetics, they still cost more than conventional oils. Decide what fits your budget and driving habits.
- Oil Change Frequency: Synthetic blends typically allow longer intervals between oil changes than conventional oils, but I recommend not exceeding manufacturer guidelines.
