There are many ways to save on FC, and all voice down to your driving style...
Some choose to go fast to reach the cruising speed to save on fuel cos they have some distance to travel on the expressway, others might take it easy and drive slow cos just going onto the expressway for a few exits...
So depends... there is no fixed rules or standards.. onli guides...

Always change at 2.5k rpm no matter clear or not clear the road will be fuel saving

And maintain rpm below 3k at 80-90kmh. No way drag to higher gear for better fc regardless auto or manual. Manual can control the gear change is better fc than auto as the latter change gear at a higher rpm.

don't drive will be better no need to pump petrol

Dont drive, park for long duration will result in petrol fuel turn to fumes.. and FC also become bad.. lol - Zero Distance and wasting petrol..

I tot this is supposed to be serious discussion of FC?? How did it become TCSS oso??? Sometimes when I so call drag, the average FC seem to go a little lower leh...

Rule is drag = low FC.

Post by fadidas on Oct 28, 2010 5:58:29 GMT 8
drag = low fc correct but faster 2 constant speed = fc rite?

Drag- requires higher rpm to reach upper gear where it will gradually up at the expense of better pick up. Eg 3.5k rpm to gear 3. It is this instance that is having a lower FC rather than I let it gear change gradually at a slow pick up.

drag = low fc correct but faster 2 constant speed = fc rite? it depends how long u can travel at this constant speed... if it is a long distance, then the extra fuel used for acceleration can be negligible for the fuel savings at cruise speed... most of the time this can't be true even on expressways unless at night...

Based on the local numbers of traffic lights, no point in faster pickup...
Based on the entry to expressway, normally got slope to speed up prior to entry to expressway... so no need drag to get to cruise speed...

I am not sure how to share because my fuel consumption has been bad on Spore roads. I have the CTE to blame. Move/Stop/Move/Stop like nobody business....

The similar question has been in my mind.....from complete stop, which way is better for FC: a. let gear shifts happen at 2000 rpm, slowly until reaching fixed cruise speed, OR b. depress the throttle deep for faster speed up to cruise speed, then maintain at the speed ?

The maths for the calculations would give u some ideas..
for your a. - distance taken to cruise speed = x, Distance on cruise speed = y...
for your b. - distance taken to cruise speed = x1, distance on cruise speed = y1
if x1 shorter than x and y1 longer than y by more than 10%, then u might have some saving in FC if the cruise speed FC is 10% or more as compare to normal road FC.
By the time u complete the math formula and equations... you might conclude that the differences might be too small for comparsion due to our short travelling distances in our SG roads...
So just drive as per normal or whichever that suits your driving style & needs.. lol
