5 Tips To Improve The Geo Metro’s MPG

You all know I love my Geo Metro but it’s current MPG is only at 52.  While that’s would be considered quite high for most car models, for my money, and considering it’s a blue tin can on wheels – it sucks!

But fear not.  I’ve done research on the “inter-web” and sleuthed some handy-dandy ways to improve the fuel efficiency.

I’ve done my research, I’ve stalked forums, and I’ve talked to my fellow Geo Metro lovers and come up with my plan to succeed no matter what. If you own a Geo Metro and want to improve its MPG like I do, here’s a list of things that we can do:

  • Cover Grille Openings – The grilles should be covered, except the one from in front of the radiator, to ensure there are no openings. A tough plastic will suffice in this situation. Additionally, the gap between the hood and bumper should also sealed. Doing this isn’t costly at all. You can do it for as low as 10 bucks depending on the materials you choose to use.
  • Reduce The Car Weight – Reducing the total weight of any vehicle will certainly improve a car’s MPG. Everything that isn’t necessary should be left out of the car. If you spending time alone with your car and don’t plan on any passengers, you can rip out the seatbelts and the back seat as well. Take it a notch further by removing the carpet and floor soundproofing. All these additional weight aren’t necessary and you’ll soon feel better acceleration because of the lesser load on the engine.
  • Adjust The Ignition Timing – Advancing it a few degrees is a safe adjustment but you still have to make sure to listen to your engine to prevent from damaging it in the long run.
  • Change To Flat Bumpers – Bumpers in the early 90’s have a round bottom. If yours still has one, time to change it to a flat one. Best place to find that is in the junkyard.
  • Change To Larger Tires – A low rolling resistance tire with a larger diameter can also improve the mileage of the Metro. If you decide to do this, change your speedometer too so that measurements are accurate.
