Frequently Asked Questions

What's the ideal cruising speed on highways to save on gas?
From our testing and what the experts say, keeping your speed between 55 to 60 mph on highways is the sweet spot for most passenger vehicles. Beyond 60 mph, aerodynamic drag significantly increases, making your engine work harder and consuming substantially more fuel.WRAL We've found even a slight reduction from 70 mph to 65 mph can make a noticeable difference over hundreds of miles.
Does tire pressure really make a difference for fuel economy on long drives?
Absolutely, maintaining proper tire pressure is one of the easiest and most impactful ways to save fuel. Underinflated tires increase rolling resistance, forcing your engine to work harder to move the vehicle.Lisbon Auto Repair Center The U.S. Department of Energy (DOE) estimates that proper tire pressure can improve your gas mileage by as much as 3%. Always check your tires before setting out, inflating them to the PSI recommended on your car's door jamb, not the maximum pressure listed on the tire itself.
Can choosing a specific route actually help me use less fuel?
Yes, route planning is more than just finding the shortest distance; it's about finding the most *efficient* path. We always use navigation apps like Google Maps to find routes that minimize stop-and-go traffic and allow for consistent speeds.AAA Avoiding congested city centers or areas known for frequent construction can help you maintain steady acceleration and avoid wasteful idling, significantly reducing your fuel consumption over the trip.
Before a big trip, what car maintenance should I prioritize to save on fuel?
Regular maintenance is crucial for optimal fuel efficiency. Before any major road trip, prioritize an oil change with manufacturer-recommended motor oil, replace dirty air filters, and check your spark plugs.Lisbon Auto Repair Center Also, getting a wheel alignment can reduce drag, ensuring your engine isn't working harder than it needs to, which we've seen directly impact our mileage on longer hauls.
Should I use cruise control on the highway to get better mileage?
Definitely! Using cruise control on consistent highway stretches is incredibly effective for improving gas mileage. It helps maintain a steady speed, preventing the constant minor accelerations and decelerations that waste fuel.WRAL We've observed that avoiding 'speed up-slow down' cycles, especially when driving manually, can cut your fuel efficiency by up to 40% if you're an aggressive driver.
