Fuel Light And Fuel Consumption - S2 R33

[No Crust Racing]

At what point does the fuel light come on? That is, how many litres remain when the light comes on?

In addition, what is supposed to be the standard fuel consumption for an RB25DET? I seem to getting pretty crap economy. $40 = around 31L of Optimax = ~220K's (or is it $45 = 34L = 220K's, can't remember) of City driving, occasional boost, before the fuel light comes on. I also have a really strong smell of fuel when I start it up, checked the boot, no smell or visible leaks in there.

Ideas and answers to questions???

Cheers

My best figures were about 300klms from half a tank (bp ultimate)

Im still doing my full tank - so far in half a tank i have done something like 200klms - thats using occasional boost (optimax)

Well that's a bit vague... Half a tank as in bone dry or the fuel light just come on? We're talking an RB25DET yes? Do you have any mods?

Also looking for ideas on my fuel smell and an answer to how many litres are left when the light comes on =)

I get 400Km to a tank

Fuel light come on with around 10L left in a RB25. If you fill up when the light comes on you'll get about 52-54L in.

The fuel smell is a bit of a concern. The most common place for a fuel leak is right under the fuel filter (check up front and not back). The clamps on the hose/filter almost always cut into the hose if you don't take care. Also, look for a splash of petrol on the ground on startup. This same thing happened to me.

If it's that then there is a DIY some where on this forum of how to change the filter/hose. Piss easy.

Man, maybe I am getting normal fuel economy then... 400K's to 65L around town is 16.25L/100... that's terrible! LoL and 14-15 seems to be what I'm getting now. Then again... i Originally thought the Fuel Light meant 5L left, not 10. Can you confirm these figures? Where di you read/see that it's 10L remaining?

[Mr Italy!]

Well, you did buy a performance car, not a toyota echo

[No Crust Racing]

Ok new info! My fuel light has just started coming on when going around corners, I filled it up, it took just on 52L so the fuel light must be set to 10L's? (Based on it being a 65L tank, is that right?) With this new info it means my car is actually getting ore like 12-13L /100K's around town. Which seems more like what I expected form this car, which for now is stock other than a POD with Heat Shield. Now that I have full fuel and know when the fuel light comes on, I should be able to run it to the light and will have a much better idea then.

Stay tuned!

P.S. Can anyone confirm or deny the fuel tank capacity and level at which the light comes on? (it certainly seems like 10L remaining given I got 52L in and the tank is supposed to be 65L)

Cheers!

Damn it. I have changed the Spark plugs. fuel filter and the OXygen sensor.

I have resetted the Ecu. The only mods I have is cat back exhaust and boost to 12 pounds.

I still manage only around 360kms per tank. And thats normal driving for the week.

WHY!!!!!!! when others are getting around 400kms.

there's really no need to drive it down to the warning light to work out fuel economy...

fill up the tank, reset the kms on the dash, drive for however many k's, then fill up and see how much it takes.

then work out how many kms/l you just got...

if you keep going down to the bottom of the tank, chances are you're gonna suck up the dirty shit at the bottom of the tank etc...

Dezz: Yeah I realised that yesterday too, oh well, got a full tank now and I have a feeling my economy is around 12-13L/100 around town which is fine, now to just find that fuel smell!

I get 350 to a tank. By "tank" I mean I fill up when it's pretty much empty, and it usually takes exactly 50L.

So I get 7km's per litre. =-[

50L's? Is this from dead empty or from when the fuel light is on? As I thought the 33 had a 65L tank?

I'll let you guys know when next I fill up how I went, I'm guessing a fuel usage around 12-13L around town.

[RANDY]

Nah, I fill up when it *looks* empty on the guage, and it always takes 50L. I was only mentioning that, so I could accurately measure what my fuel economy is.

Other quick method is to "fill 'er up", reset odometer, drive for a day, and fill up again. Measure how many k's you did compared to how much fuel you had to put in to fill it back up.

All I can see so far is that mine sucks! Even though it doesn't really run rich (according to consult programs), and there is no fuel smell, it drinks like a camel!

I have an auto S2 R33 and I fill up when the gauge reads empty. If I drive another 30km or so the fuel warning light will come on. If I fill up somewhere between when the gauge reads empty and when the light comes on, I'll get around 52-54L or so (as Kennedy said). I will usually have done around 400-450km on this much fuel, and my average fuel consumption seems to be around 12.7L/100km, which involves both city/highway driving (guessing average speed around 45km/hr overall).

If you want to figure out your fuel consumption, fill up the tank until the pump clicks (don't try to overfill it), zero the trip meter, then drive until the tank is empty, or until the warning light comes on. Fill up again (preferably with the same bowser), note the trip meter reading and amount of fuel bought. Divide fuel bought by km's travelled and multiply by 100.

I use Caltex Vortex 98 (hehe Woolies discount card ) all the time, from the same bowser every time and my fuel consumption is fairly consistent. I drive fairly lightly most of the time, but I think I would get better fuel consumption in a manual. Just about to fit the Jaycar IEBC and DFA - that should bring me down to around 11L/100km.

Hope that helps,

Ben

Hmm, exactly where is the fuel light on the dash? I think my light might not be working, as today I went below the empty line, and there was nothing.....

Has anyone ever tested if you actually get 1L out of the pumps at the servos when it says 1L on the display? Im pretty sure that they would make sure we dont get anything over 1L.

[Mr Italy!]

^ A current affair did a test on it the other night, and sure enough, almost every servo they tested ripped them off.

But hey thats not gonna change any time soon, and we've been living with it so far without even knowing it, so life will go on.

Mine does about 15L/100km's.. pretty crap.. but who cares lol..

i once managed to squeeze 58 litres into my sigma which only had a 45 litre tank. this was at a shell servo too, i went inside and had a go at the guy, he said " sorry sir but you must be mistaken about the size of your fuel tank". so as i walked back to my car i decided i needed one of their squeegees for my troubles. lol, he must have wondered what i was doing walking around every bowser trying to find the best looking squeegee to take.

I think that story is bulls#t. Today tonight ran the same story a month ago and all the servo's came back clean (most of them)
