If engaging in spirited driving, premium fuel becomes even more critical. A race enthusiast, initially hesitant to use premium fuel in his TL, quickly realized its necessity after experiencing severe engine knock during a track day.
Tip 6: Consider Long-Term Costs. The decision to use premium fuel should not be based solely on the immediate price at the pump. Reduced engine wear, optimized performance, and improved fuel efficiency (in some cases) contribute to a lower total cost of ownership over the vehicle’s lifespan. A meticulous owner, tracking both fuel costs and maintenance expenses, discovered that premium fuel ultimately saved him money in the long run.
Tip 7: Monitor Fuel Economy and Performance. Keep a record of fuel economy and engine performance with different fuel grades. This provides a tangible basis for evaluating the benefits of premium fuel. If performance degrades with lower grade fuels, this suggests the need to use premium gas.
Adhering to these tips provides guidance towards informed fuel choices. They are key to protecting and optimizing the Acura TL’s longevity, performance, and overall driving experience. The choice is yours, but should be based on fact, not cost alone.
The discussion now transitions to a comprehensive conclusion, summarizing the key findings and offering a final perspective on the Acura TL’s fuel requirements.
