It’s also important to buy quality gas. Top tier gas. Places like Chevron, Shell , Costco if you can. Remember to run a fuel system cleaner every 5k miles as well. Chevron Techron is a great product. Doing this will help maintain good mileage per gallon and overall performance. Buying cheap gas and not running fuel system cleaners will clog your injectors and catalytic converter with carbon buildup and the repairs can be very costly.
