Seeing how the price of fuel is getting so high i thought i should be driving a little bit more economically, so i looked in the book for the economical range of 5th and it said between 50 and 100... i tried going 50 in 5th but she almost died. Is my car lame or is 50 just way to slow in 5th?

..Beeza..

Im not sure if this will help...

BBBBut when i was driving the excel (before the upgrade..lol ) there wasnt a chance in hell i would be getting 50 in 5th gear, She would Labour her head off and even give the occassional cough and spit.. I also found driving in 5th gear doing under 70km wasted more fuel..BBBut then again that could of just been the Excel..lol

Dont no if its relavent but What The Hell!!!

dunno if that really helps but thanks anyway

economical is keeping the cars rpms below 2500rpm for cruise, and upshifting at 3krpm, which is what my auto does anyway....
anything above that is wasting petrol, you could shift at lower points, but unless your a quick gear changer, and wanna wear your clutch out fast.. then dont.

also, dont ride the acc pedal, keep it consistent, and use your gears over your pedal.
a/c off and less weight also helps

My getz used less at 110km/h that 100km/h.I think it have something to do with keeping the torque up to max?In 5th I doing 2700 at 100,3000 at 110.(Engine torque max at 3200).I know it not a magna,just idea's.:D

I can do 50kph in 5th as long as the road is level.

i can do 50 in 5th gear. on a flat road. however i dont. i figured there is probably more stress on the motor than its worth.

thanks, i can also do 50 in 5th but it just coughs and splatters, wasn't sure if it was a good idea or not

when i was learning to drive, the instructor and i got to talking about the usefull range of a manual gearbox in urban situs

she said that (and i belive her too from experience) that you just dont need 5th / top gear around town, for anything under 70.
you use more fuel with the engine having to 'work' harder at lower rpm (if that makes sence)

drove my mates TN carby around for a while, and it used less fuel if i left it in 4th until about 70 or so km/hr.
its all about keeping the engine in a useable rev range (where the torque is essentially)
too few revs and its working hard and not going far.

my 2c on that :)
(for the record, i pull my auto back to 4th when im doing 50 around town - dont like the way the car feels puttering along at such a low rate..)

thanks yeah that does make sense, i normally change into 5th at about 70-80 anyways

or just change over your oxygen sensor.my tp was going through 30 bucks of petrol in 2 days (city driving). so i bought a singe wire o2 sensor last week off ebay for 60 bucks and took 2 mins to put in. It also was ment for tr/ts (same engine but).
filled her up full and drove for 100 klm's and refilled to see what i could get back in . 12 litres was how much i burnt city driving.
best 60 bucks ive spent in a while.
Plus i've heard that they need (single wire o2) need to be changed like every 20-30 000 km's instead of the recomended 40-50 000.

thanks but i have no idea at all what that is

the o2 sensor can 'tell' the ecu how much fuel is not being burnt - and it allows the ecu to compensate by reducing the amount of fuel squirted into each pot.
over time they loose thier ability to 'read' the exhaust gases and send false readings back.

for 60bucks for an ebay one, cant do any harm, and have plenty to gain.
they just unscrew (with a bit of force) from the exhaust manifold and have a plug, swap in the new one and your done - just be sure to plug it back in! lol

This might not help but if you can figure out abou what ur idle rpm is at, say it's 800, for economy you need a healthy balance between lower revs and not being as low as your idle. If you have a high idle (say 1500) and you're in 5th gear doing 70 at 1500 rpm then your car is dying as it's effectively trying to push your car at it's "still" rpm's.
I tend to change into 5th at 70 km/h, there just isn't any real use for the 5th gear below then and it puts too much strain on your engine.
all the best

Change at 2,500 rpm. Use 3,000 in 4th if you want any useful acceleration when you go into 5th. Drive by the tachometer, not the speedometer. You soon get to know what the tachometer readings are at the relevant speed limits. My TP 2.6 manual HATES doing 50 kph in 4th(1,500 rpm). 80 kph is best (for me) before I use 5th.


In the stable:

TP 2.6 manual wagon.
TS 2.6 manual sedan.
TS 3.0 auto wagon.
2004 Lancer manual.

i reckon you'll notice a difference if your easier on the accelerator.
in saying that i mean not putting the foot to the floor when it makes no difference.

flattening the throttle will adjust the intake and fuel mixture afaik so keeping it steady and sensible (especially if its auto) will make a big difference.

slow and steady wins the race!

choosing a gear depends on road conditions also. i drive in 4th at 50kmph for flat roads, downhill and going up slight hills. i normally change to 5th at about 70-80. however driving on a windy road where speed may vary frequently between 60 and 90 i will stay in 4th until i reach a long straight. less where on the clutch rather than constantly changing gears

thanks its a carby so its easily adjusted, in the book it says around 750 so thats what i set mine as.
but in the mornings it always revs at about 1200 then when it warns up the revs drop back down to normal

yeah that would probably help a lot, i know I'm normally pretty heavy on the throttle but i thought seeing how its only a 4 it shouldn't be that bad. Anyways in the last few months Ive been quite light on the acc, which has helped a bit
