Simple Steps to Keep Your Car Running at Peak Efficiency
Owning a fuel-efficient car is a great way to save money and reduce your environmental impact, but getting the best performance requires consistent care. From tire pressure checks to oil changes and hybrid system upkeep, this guide outlines the key maintenance habits that can help your vehicle stay efficient for years to come.
Start with the Owner’s Manual
The best place to begin is your vehicle’s manual. It includes the manufacturer’s recommendations for service intervals, oil type, tire pressure, and more. Following these guidelines ensures your car performs as designed and helps prevent fuel-wasting issues from developing.
Keep Tires Properly Inflated
Tires play a big role in your fuel economy. Underinflated tires increase rolling resistance, forcing your engine to work harder and use more fuel. Every drop in pressure reduces efficiency, so check tire inflation at least once a month and before long trips.
Find the recommended pressure on a label inside the driver’s door or in your owner’s manual, not on the tire sidewall.
Use the Right Motor Oil
Using the correct motor oil helps your engine run smoothly. Most automakers recommend synthetic oil for modern vehicles, which reduces friction and improves fuel economy. Always follow the manufacturer’s suggested grade and look for oil labeled “energy-conserving” or “resource-conserving.”
Schedule Routine Tune-Ups
Even small issues like a dirty air filter or worn spark plugs can impact your car’s fuel efficiency. Regular tune-ups keep the engine operating at its best. Preventative maintenance may include oil and filter changes, fluid top-offs, and diagnostics to catch problems early.
For hybrid and plug-in hybrid vehicles, it’s also important to check components like the inverter coolant, charging port, and hybrid battery health.
Monitor Fuel Economy Over Time
Many fuel-efficient vehicles include a trip computer or real-time MPG display. These tools can help you track your driving habits and detect changes in fuel efficiency. A noticeable drop may indicate a need for service, such as tire issues or an engine problem.
Paying attention to these numbers also helps you build better driving habits, like smoother acceleration and braking, which help to conserve fuel.
Maintain the Braking System
Hybrids and plug-in hybrids often use regenerative braking, which captures energy and feeds it back to the battery. This reduces wear on traditional brake components, but the system still needs to be inspected. Make sure your brakes are checked regularly to maintain safety and efficiency.
Watch for Added Weight and Drag
Extra weight and aerodynamic drag reduce fuel efficiency. Remove roof racks or cargo boxes when not in use. Avoid leaving heavy items in the trunk, and skip idling when you can. Every small adjustment helps your vehicle operate more efficiently.
Don’t Skip Battery and System Checks
If you own a hybrid or plug-in hybrid, schedule regular inspections for:
- Hybrid battery health
- Inverter coolant levels
- Regenerative braking functionality
- Charging equipment condition (for PHEVs)
Your dealer or technician can check these during routine service visits, helping to ensure long-term performance.
