Default Tips for better fuel economy

Well since price keep rising, I wanted to start a thread on things to do in order to increase gas mileage. I know there are similar threads, but most of those deal with people getting bad gas mileage, and I want this whole thread to be ways to increase economy. I will start off with the common changes then hopefully I can learn some things that I can do to increase economy.

- Tire pressure
- Bad gas caps seals, bad gas caps cause over 147,000,000 gallons of gas to evaporate each year.
- Tune-up
- Oxygen Sensor
- Air filter

Step 1: Sell SSEi
Step 2: Buy Hybrid
Step 3: Lose races

But seriously though, I really have to stop flooring my car so much...but I can't help, that rush is so addicting. Damnit, I love this car.

I took the cone intake off my GP and have so far based on projected fuel usage, it appears I'll get another extra 100kms or 60 miles to the tank.

What exactly is proper inflation of tires? Mine start out at 36psi in the morning, and end up at 39psi when I get where I am going.

Maintenance is of course a big factor, but driving style is my #1. Being efficient does NOT necessarily involve driving slow. Read traffic patterns, keep your speed constant -- and take advantage of coasting. There isn't a point to stay on the throttle the extra few seconds as you're approaching the same red light.

- Where speeds permit, I try as much as possible to cruise just inside TC lockup speed, or about 40mph.

- Build your speed on downhill sections, and keep throttle input to a minimum. This'll allow you to lose speed on following uphills without falling too far back. Shut off cruise when going uphill.

Most recent tank on the Civic was just above 36mpg (6.5L/100km).




edit: At $1.20/L, which is where Toronto is right now - this is equivalent to $4.51 USD per US gallon. I drive 23,000km a year, which is 14,200 miles. The difference between 30 and 25mpg is $433 a year. 22 versus 17mpg? $870. That'* a lot of beer!

well that happens to every one. when cold air condenses and when warm it exspands.

so in theory as long and they all start out the same they will all end and the same. assuming you dont take hard turns or burn out off the line.

as the tires get warmer then the air in the tires gets warmer.

If you look on the sidewall of most tires it says to set the pressure when they are cold.

Cruise control is not always the most fuel efficient. It is handy for maintaining an even speed in flat areas, but in hillier terrain it overcompensates with too much throttle and sacrifices fuel efficiency by prioritizing maintaining the set speed. An attentive driver can do a much better job at smoothing out the peaks and valleys, like repins explained.
