Get the Most Out of Every Gallon: Summer Fuel Efficiency Hacks

Summer is a time for road trips, weekend getaways, and plenty of driving around town. But with higher temperatures often come higher fuel costs—and if you're not paying attention, those extra miles can start to add up fast at the pump.

At Japanese Auto Service, we’re all about helping you get more out of your vehicle—and that includes helping you stretch every gallon of gas a little further. With just a few small adjustments, you can improve your fuel efficiency without sacrificing your summer plans.

One of the easiest ways to boost fuel economy is by keeping your tires properly inflated. Underinflated tires increase rolling resistance, making your engine work harder to move the car. In fact, just a few PSI below recommended levels can cost you 1 to 2 miles per gallon. With temperatures rising, tire pressure can fluctuate—so check it at least once a month, especially before long drives.

It also pays to stick to your maintenance schedule. A well-maintained engine runs more efficiently, burns fuel cleaner, and lasts longer. Dirty air filters, aging spark plugs, or old motor oil can all reduce performance and lower your MPG. If it’s been a while since your last service, a quick checkup can get your vehicle back in peak condition for the season.

Speaking of oil, using the right motor oil for your vehicle can make a difference in fuel economy. The right viscosity helps your engine reduce friction, which means it doesn’t have to work as hard—and that translates to better mileage. If you’re unsure what your car needs, we can help you choose the best option based on your vehicle and driving habits.

Another factor that often gets overlooked is your air conditioning system. Yes, your AC uses fuel—especially in city driving or stop-and-go traffic. While we’d never suggest sweating through your summer drives, there are ways to keep cool without wasting gas. Use the recirculate setting instead of constantly pulling in hot outside air. It cools the cabin faster and helps your system run more efficiently.

Finally, here’s one easy habit to change that can save gas every day: stop idling. Whether you're waiting in the school pickup line or running into the store for a quick errand, shutting off your engine saves fuel and reduces emissions. In warm weather, the impact is even greater—idling with the AC on is one of the fastest ways to waste gas.

Fuel efficiency doesn’t have to be complicated. A few simple steps can help you save money, protect your engine, and enjoy a smoother ride all summer long.
