Petrol Use in the Ce's

I've found the CJ to be most economic shifting up by 3500RPM, after this the MIVEC gets a bit more aggressive on the fuel usage but likewise the MIVEC also helps to develop more torque through the lower-mid RPMs so hard to compare it to the previous cars. Luckily with the CJ having the fuel usuage on the screen helps you learn how to shift gears. Basically though I've found that accelerating lightly under and keeping the revs in the 2-3.5k band works best for me and once cruising going as a high a gear as possible without straining the motor (pretty easy to hear with an exhaust) so generally anything over 60 and the CJ sits happily in 5th gear.

The other bit to driving economically is coming upto traffic lights more gradually and stopping accelerating soon as you see the light go orange ahead of you... Often if you slow down your approach at some lights you can avoid coming to a dead stop (once you stop it then takes considerable energy to overcome the inertial effects once you want to go again...)
 
in the 4g94 the powerband doesn't start till 3k rpm, so when i accelerate i shift higher so when it drops it's still in the power band meaning less throttle to feed fuel rather then being under full load... Everyone has their own driving style and in the end it's their driving style mine is accelerate quickly to reduce acceleration time and then cruise once at speed... where others would be slowly accelerate using as little throttle as possible.
 
Just think, more throttle= more air= more fuel.

More rpm= faster piston cycle= more fuel.

Accelerating faster to the speed willconsume more fuel,
Being in a higher gear and having more open throttle will also consume more fuel,
Drive like a granny and u will use less fuel :)
Insaying that the bigger your engine the more fuel your gona dump at these times, wich is logical. Me revving my 1.5 to 5k wont be hardly as bad as revving a 1.8 to 5k.
In saying all this, u can say how u shift gears all u like, but it all depends on conditions, your not gona be cruising in 5th at 70 km/h up a hill are u.
 
to rev your 1.5 to 8k it needs to rev harder and longer than it would in a 1.8
 
i get about 550 to 600km to a full tank but i recently put king springs on and a catback with sports box and am def sure its a little more thristy than it was ,but time will tell i only got them last week :)
 
lol scatman, ur just being more of a leadfoot cos u want to hear ur zorst, springs will do nothing to fuel economy
 
00 vrx coupe
Supposed to be 55l rank according to redbook or whatever.
400-450km a tank, almost always flogging it, lives on 5k+ rpm.
Never put more than 39l of 91 octane in.
Fuel light only came on once, for about 2 seconds, then turned off again.

Something must seriously be wrong with your engine if you only get that many km from a tank...
 
Cruising obviously means your not going to be accelerating, so cruising in the highest gear possible without making your engine labour is best for fuel, even though it might not make much of a difference. Unnecessary high rpm means more fuel ignited than whats needed to maintain a constant speed, and also extra engine wear. These aren't supercars made to live at the redline, always needing to be in the 'power band'. You could cruise around in second on most roads of you wanted to, but why would you?!
 
FIlled up car today, 630km I lasted before I filled up, the light was coming on every now and then, almost constant. Filled up 44L.
 
I know this is an old thread but I get around 450 Locally when caning it and 630-640 Highway, Usually around 34-36 Litres fuel used. 1.5 2 Door Coupe with a Pod filter and all my work gear in the boot.
 
I know for a fact that with CH's, the fuel light comes on when there is just under 8 litres of fuel left in the tank. I found this in the owner's handbook, maybe you could check your book for this info.
 
I typically see 300,350 km on the odo before Empty, then you can continue to drive it up to around 500km without worry of running out. Fuel light doesn't come on till like 350-400.

lol?


Mine comes on with ~15L left, and I'll fill up when the needle is below the line halfway through the E and I'll still have 5L left till the tank is drained (noting that RedBook advises the tank is a 50L tank).
Don't swear oath by what User Manuals will tell you about fuel comp and capacity, usually they'll lie when it comes on to con you into filling up as actually draining the tank to low will not only clog up the fuel filter full of sediment but can damage the engine if it gets through.
The only manuals I look for facts, parts #'s and remove/installation guides is the Workshop Manuals as they have to have detailed "correct" information for mechanics to fix the cars.
 
Its got alot to do with condition and age of vehicle too my 1.5 got 450ks out of 40l whilst my 1.8 gets 550ks out of 40l things like o2 sensor part blocked injectors will prob have more influence on your day to day fuel consumption obv giving it full throttle all day doesn't help.
Throw into that different grades ,quality ,brands of fuel etc.
I think to through this whole thread all the attention is on the guage l evel when people need to be paying attention to how many litres there putting in on fill up vs how many ks done the gauge art very accurate eg you can fill ya tank up a quarter by driving up or down a hill etc.
At the end of the day if the fuel consumption is a concern driving a mirage or lancer then its time to start catching the bus.
 
I've only just done the odo test for a whole tank for my mr ce, it's on 420ish so far and the fuel light comes on when I'm on a hill :p
 
I get roughly 450 out of a tank in my car street driving and it's auto, and 600km high way. Sounds like you have a problem or you're driving too hard.
