I drive a lot for my sales job, putting about 500 miles a week on my 2020 sedan, and with gas prices staying high, I'm trying to maximize my fuel economy to save money. I already keep my tires properly inflated and avoid aggressive acceleration, but I feel like I could be doing more. For other high-mileage drivers, what are your most effective fuel economy tips that actually make a noticeable difference? Does using cruise control on the highway help significantly, and is there an optimal speed range for the best mileage? Also, are there any maintenance items beyond the basics, like air filter or spark plug changes, that have a real impact on MPG?
