Everything to Know About Your Mazda's Fuel System
Best Tips on Using Premium Gas for Your Miata
1. Always Check Your Owner’s Manual
Before filling up with premium gas, confirm that your Mazda Miata recommends or requires it for best engine performance.
2. Use Top-Tier Gas Stations
Buying premium gas from reputable brands helps keep your fuel system cleaner and improves long-term reliability.
3. Don’t Mix Premium and Regular Gas
Stick to one fuel grade per fill-up to maintain consistent combustion and engine health.
4. Monitor Fuel Economy Changes
If you notice a drop in fuel efficiency after switching fuels, it might be a sign to switch back or address maintenance needs.
5. Keep Up with Regular Maintenance
Changing important parts like air filters regularly will support cleaner fuel combustion and better mileage.
6. Avoid Overfilling the Tank
Stop filling when the pump clicks off to prevent fuel system damage and improve emissions control.
7. Use Fuel Additives Cautiously
Only use fuel system cleaners approved for your Miata to avoid harming sensitive engine parts.
