Stagea Fuel Economy

[iamhe77]

I still seem to be the anomaly here.

Driving to Canberra and back the lowest tank for me was 8L/100km.

Maybe it's because I don't usually use the aircon?

Awesome figures Jase! The only time I had better economy was with the Fcon in and a long trip up the Hume Hwy.

No chance I could get that with just the standard ecu. Are you running a remapped ecu and rwd with very skinny tyres at insane psi or something?

[GoldZilla]

Screw you all!!! According to the stats I've been gathering, I'm averaging 14.87l/100kms.

I've got a full exhaust, FMIC, PowerFC and a GReddy EBC - must be the short trips and heavy right foot. I don't speed anywhere, but I love the feeling of acceleration, so that's killing my fuel economy.

That was on Potenzas. They were pumped up at the time but nothing ridiculous.

Only mod that I believe may have made a difference to fuel economy is the runner spacer. Ever since I chucked that in it seems more than happy to sit in 5th/overdrive from about 70kmh and up. Actually seems to have a lot more torque from say 70kmh to 90kmh than before.

Hmm I'm averaging 14.9 mostly city driving in my stock nm35 I gotta look into improving this I don't even thrash it (much)

Pretty sure o2 sensor is a common complaint of shitting itself...

[pomnz]

Is there any way I can tell if this needs doing? I'd rather not drop $250 "just to see".

Disconnect it & use up a tankfull, see if any change?

Here's stats from 3 fill ups on my C34 S1- stock everything except no cat. 'Z' 95 fuel.

05/03/12: 10.72/100km

08/03/12: 9.96/100km... first time ever getting into 9's

13/03/12: 10.6/100km... this one is the most common result

My 34 S1 RS Four stock everything except no cat, burns about 20-23 L/ 100 km in city, and about 15-16 L / 100 km on highway. 95 fuel. I drive not faster than 110 km/h, but I like to speed up by pressing the gas pedal to the floor. Our fuel is terrible, so If I tucked your petrol, consumption would be less.

I still have the same o2 sensor in from when i bought the car. Still get 600k's before fuel light comes on. Still give it beans most days. Car is now @ 308,232klms.

NEVER buy Matilda fuel. It was PULP but found performance was down and only got 450klms to a full tank. Shell 98 all the time, everytime for me.

Edit: I totally forgot to say - At 180,000 k's I did pull the o2 sensor out. I put it in a small tub of fuel and used a new paint brush to clean the sensor tip, in through the little slits too.

EDIT: Wait, you have a VQ. You could be right on the price.

i get 20L per 100 city driving on my LiLPG! get 14L per 100 on the freeway fully loaded with aircon.

[3PointJ]

I'll check what we get, but we always run on Shell 98 Octane... f**king 1.70 p/L here atm... Yeeeewwwwww

[bjd]

_{I got 13.9/100km but I just had JJR bellmouth put on with 3 inch hi flow metal catco cat and Trust cat back exhaust and halfway through the tank with 290km out of it so far...}

[Down_Shift]

I got 12.47l/100km on my very first tank with quite a bit of spirited driving, was testing the car out when i just got it.

Then 11.3l/100km on my second tank, these are with 85% suburban driving.

Only mod is a cat-back but on a manual hence the low figures?

[KiwiRS4T]

Just filled my S1 manual RB30/25. I have been driving normally - changing up at 2 -2500 revs, the odd boost on the motorway and it took 62.65 L for 448km so about 14L per 100km (mostly short trips less than 10km - four or five about twice that).

[numleg]

I get around 12 to 13 Ltrs per 100 KM for combined city driving and Sydney to Orange Highway run, I'm no boy racer but i do like the sound of my car on boost...

[STAG250]

71 litres for 570 odd km's. Getting on for 150,00 km's mileage now. Have cat fuel filter fitted but seems to make little difference. Upwards of 200 km's on first quarter tank, open highway, promised much but failed to follow through in city driving. I expected better combined based on past performance.

BTW: MY rank should be VQ25DET, to whom that matters.

I'm monitoring my fuel consumption following the road tune. It seems quite reasonalble concidering the changes I have made. Its hard to measure properly, because the Mrs trips are not long, but I'll have a crack.

Staqg250 - your Rank is based upon your post count. You start as a RB20e then progress ir RB20de, det, RB25de, det etc etc up to RB26dett with something like 10,000 posts.

A few of us smart cookies just changed it to something more suitable for M35 owners....

[lilcrash]

Ok finally had a gentle driving week in my car and I've come back with 13.4l/100km, all highway. Alot higher then it used to be before the tune but with low level mods it's probably about right.

[Hanso]

I've gone back to Shell 98 octane and I am getting far better fuel economy now than when I was running Caltex Vortex 98. Last time I let the tank get down to near empty I had done 500km, and it took 61L to fill the tank. Now after a few tanks of the Shell fuel, I was on 275km at a half tank of fuel before I filled up this morning. I mostly drive country roads/highway going to and from work here in Canberra, all the while in the midst of the daily tradie grand prix.
