# 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.

Combine errands. Plan routes to cut miles. Track MPG with your dashboard display.

## 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.

Track your progress. Small changes add up to big savings at the pump.
