Fuel Saving Tips


Recommended Posts

The most important consideration is that you bought the right vehicle - small (or at least, not SUV-sized) and preferably a diesel. Manual transmission is the best. If mercedes ever came out with a 7-speed stick shift, 1 liter turbodiesel mini car, I'd bite instantly.

 

But assuming you are stuck with whatever heavy lump of metal you got, the next consideration is road cruising speed. The speed has to be as low as possible and still let the engine (barely) run clean. For most cars, this means 60 - 70 km/h at top gear, where the revs are at just 2000 RPM or so - a little lower revs and the engine start to run rough and efficiency drops.

 

I will not go into the usual details about smooth starts and such. For one I mostly do distance driving where I cruise at speed for hours.

 

Last consideration is car mechanical condition - engine tune, tirepressure, and air filters (ETA).

 

So maximum fuel efficiency boils down to (in order of importance):

 

1. smart enough to get the right vehicle

2. disciplined enough to drive slow

3. experienced enough to understand car mechanics.

Tornado Fuel Saver.

It came out a few years back in Canada and US.

i bought this for my E46 a few years ago... basically, its a turbine-looking cylinder that fits into your air intake.

check out ebay.... there's a hundred other brands and types now.

 

personally, i didnt notice a difference.

but others have nothing but good to say about it.

Accelerate with care

Jack-rabbit starts are an obvious fuel-waster -- but that doesn't mean you should crawl away from every light. If you drive an automatic, accelerate moderately so the transmission can shift up into the higher gears. Stick-shifters should shift early to keep the revs down, but don't lug the engine -- downshift if you need to accelerate. Keep an eye well down the road for potential slowdowns. If you accelerate to speed then have to brake right away, that's wasted fuel.
