7 Ways to Improve Gas Mileage


Everybody’s trying to save on expenses today, whether it’s large or small, anything helps. No matter what kind of car you drive, we all wouldn’t mind saving some money at the pump right? It’s not uncommon to feed that pump $100 a week, but what if we could cut that expense to $75? That would be an extra $600 a year! Let’s get cracking.

1. Slow down. I know, it’s tough, but that’s where most of the waste is coming from. The fuel economy of a car decreases by 20% when we cruise at 75mph vs. 55mph. You might have to drag yourself out of bed 5 minutes earlier, but it might be worth the $20 savings per week.

2. Go easy on the A/C. This one is almost impossible for me – I live in south Florida! But, the winter season is coming and I’m looking forward to opening the sun-roof rather than running that A/C. If you live in a northern state, it might be a little easier to do without the air conditioning. Find a shady spot to park, or use a windshield cover to block the sun.

3. Don’t buy that cheap oil. If you are anything like me, I used to go to Auto Zone and find the absolute cheapest oil I could find. It’s all the same isn’t it? I was wrong. Oil is very important to the life-blood of your vehicle. A high-grade synthetic oil is said to improve gas mileage by 12% (due to a more efficiently running car). I guess an extra $5 would be worth the $50-$100 is savings.

4. Use your cruise control. This one is a no-brainer. The stop-and-go and speed-up-slow-down driving burns more fuel than keeping a constant speed. Stick to your lane, go an average speed, and you could save some money.

5. Check your tire pressure. If your tires are a little low on pressure, this puts a drag on your car. Check your manual and make sure they are at their optimal pressure.

6. Buy some Fuel Injector Cleaner. I always wondered if this stuff really worked, or if those car guys were just out for my money! Well, after some extensive research, Fuel additives do help clean, and even help restore, those fuel injectors. By doing so, it can certainly reduce fuel emissions, therefore saving you money!

7. Combine trips. If you have a spouse or significant other that also drives a vehicle, maybe it’s time to start combining trips. If your wife practically passes your work to get to her job, why not just take one vehicle! Just by carpooling half of the time, this will save you 25% in fuel expenses! If you don’t have more than one vehicle, do your best to plan a route before doing your driving for the day. One big loop will save you a ton of gas compared to a bunch of trips to and from your house throughout the week.

I hope this gives you a better idea on how to save money at the pump. If you have more ideas, leave a comment and let us all know!

  1. In my new car, there is a real-time digital gas consumption display on the dash. That has helped a lot in conserving gas. I’ve learned that I can still move at a decent speed but use less gas and therefore get better mileage. Because of it, I now drive smarter.

    • That definitely helps! Thanks for the comment Jon!

  2. Really good advice. My car doesn’t need to much gas, but there’s surely a lot we can do to keep consumption even smaller. By driving at an economical speed, getting the best oil for the engine, to keeping our tires well inflated, anything can help make a difference

    • All these things certainly do make a difference. Just by driving slower and more carefully, I was able to increase my mileage by 2 mpg!

  3. Great tips! I almost always use cruise control. Makes driving much more easier!

    • Cruise control is a great way to relax and improve your gas mileage. Nice work! And thanks for the comment.

  4. I like to think that I do all of these things, even though I sometimes blast the AC probably unnecessarily.

    • Haha. Well yes, that would hurt your gas mileage, but it would help your overall comfort. You’ll just have to weigh the pros and cons. 😉

    • You’re welcome Marissa!

  5. Hey! I do all of these but my mileage doesn’t really improve… What am I doing wrong?

    • Make coasting your friend. I’ve seen people do all the little things, but they are still punching the gas off the line and slamming their brakes at red lights. This is terrible for your gas mileage. Drive smoothly – that will make a big difference as well.
