2 k! How long does it take you to get 60?

This morning I tried a little experiment. Didn't know this thread was up though

Anyway, filled up this morning and was watching the average consumption meter to see how bad it would start off with the stop/start traffic on Parramatta Rd. A few km down the road I noticed it shoot from 12.2 up to 13.8 accelerating up a slight incline to 60km/h. I was just driving it as normal (for me) - changing up a bit over 2k. By the time I had gotten to the next set of lights it had dropped back to 12.2 again so I thought "let's see how high this baby will get WOT in 1st through to 60". I ended up shifting up at 50km/h, to second, 4th and into 5th pretty quickly afterwards to cruise at 60. Astonishing thing for me was that it only got up to 13.0.

Only reason I can think of is that the second time I spent less time accelerating (I'd say 1/3 to 1/4 of the time) allowing me to get back to a cruising throttle opening in a high gear earlier.

Now, I don't think I'll be nailing it at every set of lights but I sure won't be pissing about anymore off a standstill

I think the best way is to make sure you aren't loading the engine to high hell in high gears while going slow, sometimes early shifting can be terrible for econemy because you then have to use more throttle in the next gear up to get it accelerating at a decent pace.

Ive found that the best way to increase economy is to drive smoothly - not slow or at set shift points, just be smooth. I find that increasing the throttle with rpm rather than stomping on the pedal or being a nana and not providing enough pedal to be the most effective. Also increasing brake pressure the more the car slows rather than lightly braking over a longer distance or braking at the last minute works well. I get about 8-9l per 100km out of my tt when i drive like this.

Out of my 2.2 auto,
It loves the foot to the floor and shooting up to 100ks :Pardon: (for highway driving) Doing it this way, also feels like its cleaning out the cob webs
Around town, I try getting the car changing when I hear the perfect burble, which in my car is at about 2100-2300.

But I agree with what a couple have said before me, smooth driving and feeling the load of the car is the best way to know when to change.

This thread is full of fail. Go buy a Prius.

the car is using petrol to idle.

The movement of the car is turning the motor over. The amount the engine is reving does not translate directly to the amount of fuel being used
