# How Can I Improve My Gas Mileage?

Keep tires at the right pressure and drive smoothly to boost your gas mileage right away. Most vehicles gain 3-10% better MPG from these steps. According to AAA's 2025 fuel report, proper tire inflation alone improves efficiency by up to 3.3% (Source: AAA Fuel Economy Guide, 2025).

## Quick Wins for Better MPG

Start with these easy actions. They work for most cars and show results fast.

| Tip | Expected Savings | How Often |
|---|---|---|
| Inflate tires to recommended PSI | 3% MPG gain ($0.10-0.20/gallon) | Check monthly |
| Replace air filter if dirty | 5-10% better efficiency | Every 12,000 miles |
| Use cruise control on highways | Up to 14% savings | Every long drive |
| Avoid rapid acceleration | 10-40% less waste in city | Daily driving |

"Tire pressure checks save drivers an average of 2-4% on fuel yearly," says the Sidekick Research Team, based on analysis of 1,200 verified owner records as of March 2026.

## Drive Smarter to Save Fuel

Ease off the gas pedal. Hard starts and stops burn 15-30% more fuel on highways. Drive 5-10 mph slower than usual for 7-14% better mileage. Each 5 mph over 50 mph costs an extra $0.31 per gallon, per EIA 2026 data (Source: EIA Annual Fuel Report, 2026).

Use cruise control to hold steady speeds. It cuts fuel use by up to 14%. Turn off your engine during long idles. Idling wastes 0.5-1 gallon per hour.

In the 19308 area, steady speeds help beat local traffic waste. Sidekick tracks your habits to show real MPG gains.

## Maintain Your Vehicle Regularly

Check tire alignment every 6,000 miles. Bad alignment drags fuel economy like pulling sideways for miles. Rotate and realign tires with oil changes to avoid uneven wear.

Swap spark plugs if worn. New ones make engines run smooth and boost MPG by 4%. Clean or replace air filters often. Dirty ones force engines to work harder, cutting efficiency 10%.

Tighten your gas cap. Loose caps cause 2 MPG loss from vapor escape. Fill at slow nozzle speeds to avoid spills.

Reduce weight and drag. Remove roof racks when empty. They cut MPG 5%. Every 50 lbs extra drops efficiency 1%. Pack light for trips.

Skip AC in mild weather. It costs 1-4 MPG. Open windows instead until hot days hit.

## Fuel Choice and Habits

Buy top-tier gas. It runs cleaner without impurities. Avoid running tanks near empty. Debris clogs filters and hurts performance.

Tune up yearly. A tuned engine gains 4% MPG on average (Source: Department of Energy Gas-Saving Tips, 2025). Track costs with Sidekick. It shows your MPG trends and suggests tweaks based on local 19308 gas prices.

Owners who follow these tips save $300-600 yearly, per Sidekick data from 950 vehicles (N=950, Q1 2026). Start today for quick wins.
