How Can I Improve Gas Mileage in My V8 Sports Car?
Keep tires properly inflated, drive at steady speeds, and maintain your engine. These changes improve fuel efficiency by 5-20% in most vehicles. You save hundreds of dollars each year on gas.
Quick Wins for Better MPG
Start with easy fixes. They deliver the biggest gains fast.
- Inflate tires correctly: Underinflated tires drop mileage by 0.2% per 1 psi low. Check pressure monthly. Use the door jamb sticker for the right PSI. Proper inflation boosts efficiency up to 3%.
- Lose extra weight: Remove roof racks, heavy tools, or junk from your trunk. Each 100 pounds cuts MPG by 1-2%.
- Change air filter: A dirty filter hurts combustion. Replace it every 12,000 miles or yearly. Clean flow adds up to 5% better mileage.
| Tip | Potential MPG Gain | How Often to Check |
|---|---|---|
| Tire pressure | Up to 3% | Monthly |
| Air filter | Up to 5% | Every 12,000 miles |
| Remove weight | 1-2% per 100 lbs | Before every trip |
Drive Smarter to Save Gas
Your habits matter most. Aggressive driving wastes fuel.
Accelerate gently over 5 seconds to 20 mph from a stop. Hard starts burn 20% more gas. Use cruise control on highways. It holds steady speed and cuts use by up to 20% at high speeds.
Avoid jackrabbit launches and hard brakes. Coast to slow down. Stay under 65 mph. Speed over that adds 20% drag.
"Keeping momentum smooth boosts fuel economy everywhere," says the Hagerty team.
Turn off AC when possible. It raises use by 5-20%. Pump gas early in the day for denser fuel. Skip topping off after the nozzle clicks.
Maintenance That Pays Off
Tune your engine. A super tune fixes timing and spark. Dyno tunes optimize curves for power and economy. Swap to a clutch fan. It frees power when not needed.
According to AAA data, proper maintenance lifts MPG by 10% on average (Source: AAA Fuel Economy Report, 2025). Sidekick tracks your fill-ups and maintenance to show real savings.

Advanced Upgrades
Consider overdrive gears if you have an older setup. They drop engine RPM on highways. Performance air intakes add 5% gain by better airflow. Exhaust upgrades reduce backpressure for small boosts.
"Fuel-efficient driving saves hundreds yearly and cuts emissions 25%," notes Natural Resources Canada (Source: NRCAN Driving Techniques Guide, 2025).
Based on Sidekick data from 5,200 verified owners as of February 2026, drivers who check tires monthly and drive steady gain 12% better MPG on average.
