Those are very useful tips, Jim!  It's refreshing compared to other lists that usually mention things like checking tire pressure, removing unnecessary weight and using cruise control ::)

Good points.. I use most of them when I drive today.  Reading the lights and the road ahead is key so you don't have to stop at the lights and accelerate again.

Going 100 or 90km/h on 400 series highway isn't recommended, though.  It will cause most, if not all, cars trying to pass you and I think it just increases the chance for accidents for other drivers.

What is the point in driving then? Accelerate slow so the old people with walkers pass you. Windows down to smell the pollution and rotting garbage. Gee, might as well ride a bicycle.  ;D

I use most of them also. Especially reading the lights and the road. Taught my son this technique when I was teaching him to drive, and when I turned over the teaching to a professional (just be before my son was going to go for his license) he was impressed that my son was doing that.

Accelerating from a stop light, I have no problem with our van doing this, but the Subaru, seems to need more "gas" just to get it to move. Could be a sticky throttle I guess?

As for going downhill and letting the vehicle accelerate, not so much. If there is a traffic light at the bottom of the hill or even part way down, I must admit I downshift to provide a controlled descent of the hill, so if the light changes, I can brake gently.
I thought I was lost once, but I was just misplaced

This is exactly how I drive my car in Vancouver's awful traffic. There is really no point trying to get up any speed here as the traffic is too heavy and there are too many stop lights. The torque of my vehicle will allow me to keep up with any traffic without ever going above 2000 rpm. Added bonuses are better brake and tire life, less stress and happier passengers. The key is smoothness and watching the traffic and signals as far in advance as possible.

Another technique. I get in the car, set up my iPhone, put on my seat belt, then start the car and drive away sedately and allow the car to warm up under load. Same when stopping. I turn off the car and then close and disconnect everything. I also find a K&N air filter helps as well as synthetic oil.

Doing this, I can get 10 L / 100 km in the heaviest traffic one will ever experience in Canada. This handily beats the rating of 11.3 L / 100 km. When I first got the car, it had 8000 km on it so it was broken in. I couldn't resist gunning it all the time since it was a new toy. I saw a few tanks in the 13 L / 100 km range and one at 14, so I know these techniques work.

But...and a big BUT....when I am driving over Roger's Pass, I don't give a darn about how much fuel I am using... ;)

Get a ScanGauge or monitor instant fuel economy for a quick learning curve of tricks to save more fuel.  Most cars consume no fuel when coasting, so the longer you coast to lights, reading traffic or downhill, the better.

My last tank returned 8.37l/100 km over 693 km of rural roads, highway and commuting to work.  On that front, avoid traffic and short city errands at all costs (if you can of course) for best results.  This will destroy mileage on any vehicle.  I walk and ride whenever possible or group short drives together.

One last thing, monitor traffic on Google Map before you leave and pick the best route.  Very handy at times.

Oh yeah, just forgot as I watch my neighbour move the fleet in his driveway.  Avoid starting a vehicle just for the sake of having to move it in your driveway or on the street.  If you start it, drive it or don't touch it.  More wear and will kill mileage with no km driven on a cold engine.

Hmmm, avoiding city traffic...not an option here!

I would also add "learn" the operating characteristics of your vehicle. I find with my Echo is that lifting off the accelerator will slow it down fast so less braking involved.
Great article....    ;)

I just drove 70 miles for $2.

I decided to take a weekend outing to Stave Falls instead of a more local area for a good reason.

Gas in Mission was $1.15 plus a 3.5 cents/liter coupon - or $1.11 and a half.

Lower mainland is $1.32 to $1.34

So I saved enough to pay for the trip almost and had a good outing for almost free.

I plan to do that for each tank just to avoid all the transit and carbon taxes. And the trip will produce more carbon as a bonus.
