Poor Fuel Quality
Poor fuel quality can lead to knocking and reduced performance in the RX-8. Using low-octane fuel can cause the engine to run inefficiently.
DIY Fix
Always use high-octane fuel as recommended by Mazda. Consider using a fuel additive to clean the fuel system and improve combustion.
Clogged Fuel Filter
A clogged fuel filter can restrict fuel flow, leading to power loss and poor engine performance.
