How to Get Better Gas Mileage in Your 2020 Porsche 911
Your 2020 Porsche 911 gets 19 mpg city and 24 mpg highway on EPA tests for base Carrera models. You boost this by 3% to 20% with simple steps. Check tires each month. Replace air filters and spark plugs on time. Drive smooth. Use cruise control. Turn off the engine at idle. Drivers reach 22 to 26 mpg on highways after these changes.
Check Tire Pressure First
Low tire pressure forces the engine to work harder. Wide performance tires create more rolling resistance. Use a gauge monthly. Set front tires to 36 psi and rear tires to 44 psi when cold. Check the driver's door sticker or owner's manual for exact specs. Each psi below target cuts mpg by 0.2% to 0.4%. Proper pressure adds up to 3% better mpg. It sharpens handling too.
Keep Air Filters and Spark Plugs Fresh
Dirty air filters starve the flat-six engine. The engine burns extra fuel to compensate. Inspect filters at every oil change or 10,000 miles. Replace if dirty. Porsche filters cost $100 to $200. They pay off quickly.
Old spark plugs cause misfires. They disrupt smooth running. Replace them every 40,000 miles per Porsche schedule. New plugs burn fuel cleaner. They save 2% to 5% on gas. Throttle response snaps back.
Use Right Oil and Tune Ups
Use Porsche-approved A40 synthetic oil. Wrong oil thickens and drags down mpg. Change it every 10,000 miles or yearly. Schedule full tune-ups to fix sensors and ignition. A poor tune wastes 4% to 10% more fuel.
Drive Smart for Biggest Gains
Hard acceleration and high speeds slash mpg in your quick 911. Aggressive driving drops highway mpg by 15% to 25%. Stay smooth. Choose Normal mode over Sport Plus for daily drives. Cruise control keeps steady speeds at 65 to 70 mph.
Plan routes to dodge traffic. Combine short trips. Avoid jackrabbit starts at lights. They guzzle premium gas fast.
Here is a table of mpg gains:
| Tip | MPG Boost | Notes for 911 |
|---|---|---|
| Tire pressure | 3% | Check cold, monthly |
| Air filter/spark plugs | 5% | Follow Porsche schedule |
| Smooth driving | 15-20% | Normal mode, cruise |
| No idling | 2-5% | Off after 10 seconds |
| Drop weight/roof rack | 5% | Empty trunk |
Cut Drag and Idling
Idling burns 0.5 gallons per hour. Turn off the engine after 10 seconds at lights. Use remote start if equipped.
Ditch roof racks or cargo boxes. They spoil the 911's sleek shape. This costs 5% to 10% mpg. Pack gear inside. Roll windows down below 50 mph instead of max AC.
Model-Specific Tips
Shift PDK automatics to overdrive early. Lower revs cut fuel use. Track fills with Sidekick for maintenance reminders and cheap gas stations.
