Picking the correct fuel type is important to keep your car running efficiently and to avoid expensive repairs. With so many options like gasoline, diesel, hybrid and electric vehicles now on the market, how do you know what fuel works best for your make and model? This comprehensive guide examines the different fuel types, provides tips to maximize your fuel economy, and answers common questions to help you make the right choices at the pump.

Gasoline — The Most Common Automotive Fuel

Gasoline, also known as petrol, is by far the most prevalent fuel for cars and light trucks today. There are a few key things to know about gasoline:

  • Octane Rating — This measures the fuel’s resistance to igniting prematurely, which can cause knock and engine damage. Most cars require 87 octane regular gasoline, but some models need or recommend premium 91–93 octane for maximum performance. Check your owner’s manual.
  • Formula — Gasoline is blended with various additives like detergents and ethanol. Top tier gas from major brands meets higher standards for additives that help keep engines clean.
  • Prices — Regular gasoline costs less than premium per gallon. But premium is recommended for high-compression engines to prevent knocking and ensure full power output.

Gasoline remains the go-to choice for most passenger vehicles, but diesel and hybrid options are growing in popularity.

Diesel Fuel — An Efficient But More Expensive Option

Diesel is another liquid fuel choice compatible with certain car makes and models:

  • More torque & better mileage — Diesel engines get up to 30% better fuel economy and produce more low-end torque, though at lower RPMs than gasoline engines.
  • Higher fuel costs — Due to higher refining costs and taxes, diesel often costs 10–30% more per gallon than regular gasoline.
  • Fewer options — In the US only around 3% of cars run on diesel. But it’s popular for pickup trucks, SUVs and heavy-duty commercial vehicles.
  • More maintenance — Diesel engines and particle filters require diligent maintenance to operate correctly. Oil changes, in particular, must adhere to proper intervals.

If you do lots of towing or highway driving, the extra mileage and torque of diesel may pay off despite higher costs. But for typical passenger cars, gasoline is usually simpler.

Electric Cars — The Future of Fuel

Electric vehicles (EVs) forego liquid fuels entirely to run on battery-supplied electricity:

  • No gas required — EVs use no gasoline or diesel, just pure electricity stored in large onboard battery packs.
  • “Refueling” — EV batteries are charged by plugging into wall outlets or dedicated charging stations. A full charge can take 4–12 hours.
  • Low operating costs — No gas fill-ups needed, just cheaper electricity. Maintenance costs are also lower without combustion engines.
  • Limited range — Full battery charges support 80–400 miles of driving range. Plan longer trips carefully around charging stations.

All the major automakers are investing heavily in electric vehicles as battery costs keep improving and charging networks expand.

Hybrid Cars — The Best of Both Worlds

Hybrid vehicles combine gasoline engines with electric motors and batteries:

  • Great mileage — The electric motor assists the gas engine to reach 35–55 mpg in combined city/highway driving.
  • No plug-ins required — Batteries charge through regenerative braking and the internal combustion engine. No external electricity source needed.
  • Seamless operation — Vehicle computers manage power from the electric and gasoline systems for optimal efficiency and performance.
  • Higher costs — The dual power systems make hybrids $4,000-$10,000 more expensive than comparable non-hybrid versions.

Hybrids achieve excellent fuel economy without range anxiety, but at a price premium. They make the most sense for frequent city drivers aiming to maximize mpg.

What Fuel Should You Use in Your Car?

Deciding which fuel meets your needs depends on several factors:

  • Vehicle make and model — The manufacturer’s recommendations, engine specs and fuel type compatibility vary. Check your owner’s manual as the foremost guide.
  • Driving habits — Frequent long trips at highway speeds favor diesel. Short urban commutes are ideal for hybrids. Assess your own real-world usage.
  • Fueling convenience — Those without easy home or workplace charging access may struggle with pure electric vehicles. But most drivers have easy access to gas stations.
  • Fuel pricing — Diesel, hybrid and electric vehicles carry price premiums that take years to recoup through efficiency savings at the pump. Crunch the numbers.

While gasoline remains the dominant choice, assessing your needs helps determine if the advantages of diesel, electric or hybrid models justify their extra upfront and operating costs.

5 Ways To Improve Your Car’s Fuel Economy

Boosting your miles per gallon saves money on fuel costs and reduces environmental impact. Here are 5 proven tips:

  1. Drive slower — Wind resistance rises exponentially above 50 mph. Every 5 mph over that costs an average of $0.30 extra per gallon used.
  2. Avoid excessive idling — Idling for more than 10 seconds uses more gas than restarting your engine. Don’t idle unnecessarily.
  3. Watch the lead foot — Aggressive acceleration guzzles gas. Gradually accelerate up to speed. Going from 0 to 30 mph steadily vs. stomping the pedal cuts fuel use in half.
  4. Maintain proper tire pressure — Underinflated tires create more rolling resistance. Inflate to your vehicle’s recommended PSI.
  5. Reduce cargo weight — Clear out unnecessary items in your trunk and interior cabin to lighten the load. Less weight improves mileage.

With smart driving habits and proactive care, you can extend the range of every gallon or electric charge. Saving fuel saves money.

FAQs

How often should you get gas?

There’s no set rule, but aim to refuel when your gas gauge drops to 1/4 tank. Letting it get near empty risks running out of gas and damaging the fuel pump.

Is premium gas worth it in a regular engine?

No, using higher octane premium gasoline does not improve fuel economy or provide benefits in a regular engine not tuned for it. Stick with regular gasoline.

Does fuel economy improve over time?

Typically yes, as engines break in fully during the first 5,000–10,000 miles. But fuel economy gradually declines as engines accumulate wear over decades and hundreds of thousands of miles.

Should I use top tier gasoline brands?

Major brands like Shell, Chevron and ExxonMobil follow Top Tier standards for optimal gasoline additive packages. This provides some protection against buildups.

How long can gasoline stay in a car’s tank?

Gasoline has a shelf life of 3–6 months when stored properly in a sealed tank. After that, oxidation leads to declining fuel quality and performance.

Understanding the right fuel choices for your driving needs helps optimize efficiency and costs. With options expanding beyond just gasoline, there are more ways than ever to wisely fuel your car.
