Proper Fuel Cinsumption Or...

[R33ryda]

hey guys,

i realise that there are topics on this but theyre all not quite exact.

what im asking is, my 95 R33 series one n/a, when i fill it up, i usually only get say about 350 kms, i dont really thrash the motor, just normal driving, and the motor is completely stock.

is this normal or sumthings up?

any suggestions on increasing my fuel eco? and how much so i can budget $$$.

Thanks.

by the way, how many litres my skyline? ive always wondered.

you have a 2.5lt engine, just to let you know i get about 450k's out of my r32 turbo skyline, so i would say somehting is up with your car, i would check spark plugs, timing etc and make sure all is good

The r33 fuel gauge is notorious for being inaccurate. you should do the fill up and mileage calculation to determine your actual fuel consumption / 100km. then work from there.

if you havent done a major service for a long time. it would pay to do so.

I'm guessing RB25's (your engine) have oxygen sensors in exhaust the same as older RB's

My car is using a lot of fuel at the moment due to a choked up catalytic convertor, which has caused the

O2 sensor to play up..... they can just wear out anyway. Apparently common for them to go in hotter weather.

If the ECU is not getting accurate readings..... it will over fuel so as not to run too lean and damage engine.

Check/get checked your O2 sensor..... take it to a mechanic and get them to do tune and check for stuffed sensors..... could just need a good tune up.

def the 02 sensor.

just pull it off. and hold the washer on the end.... than shake it with your hand.... if you can feel and here the a lil thing inside it rattling around... its stuffed.

so get a new one. will make the biggest diff ever dude. prob make your car go better to.

cost.... Around 80-100bucks

o2 sensor is $120 for an NTK one.

R33 fuel tank is 65L

haven't had a look, but how hard is it to get the o2 sensor out?

[Gazee]

Wow 350 to a full tank... i get around 400 and thats with mods too... this is only when my foot feels like a feather for a week changing gears at 3-4k... Do alot of people get around 400 or is it usually 300-350?

you just un clip it from the main wire that runs to the ECU. the i think its a 12mm spanner. to un screw it. its located on the zorst manifold. easy to find. it has 3 wires coming out the back of it.

I usually get just over 400kms to a tank (12l/100km) and I have a R33 GTST with just an exhaust and pod filter

[Greg]

I average 9.8L/100km

This is over 550km per tank if i delay filling up long enough

[burnsie]

get bout 500k's and thats giving it abit.

[jjjDavey]

i get about 430..on a 93 r33 GTST..

im wondering though, do the r33s have an empty light cos ive never gone that low before

"get about 430..on a 93 r33 GTST..

Yes R33s have an empty light. But im told that it comes on once the needle gets BELOW the empty line. Im pretty sure that R33s have a 22L reserve, so when you look at your fuel gauge and it says empty, youve only used 2/3 of a tank. Well thats the case with mine anyway

[Cubes]

I remember with the 32's when you hit the empty light you have left ~10litres.

The old Rb20DET running 1bar used to average470km's per tank and that was giving it a bit also.

The RB30DET has dropped a touch to ~450km's per tank giving it a bit also.
