CHO50N Posted October 15, 2006 Share Posted October 15, 2006 Just got a R33 GTR and only managed 217kms from a full tank of premium, this is just normal driving and not to much "spirited driving" Does this sound right? or does car need a tune. Thanks guys Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/ Share on other sites More sharing options...
nizmo_freek Posted October 15, 2006 Share Posted October 15, 2006 Hmmm dosent sound right to me, is the car running very rich for some reason???(is the rear bumper just above your muffler stained black?) Or possibly your factory petrol level sensor is faulty or something, could also be your oxygen sensors, i would get it checked out at nissan or some other performance shop.

CHO50N Posted October 15, 2006 Author Share Posted October 15, 2006 Thanks mate, When going hard there is a bit of smoke (only seen in headlights of cars behind) but bumper is not stained black. Will get it checked out soon. Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/#findComment-2585543 Share on other sites More sharing options...

R33TOM Posted October 16, 2006 Share Posted October 16, 2006 are you sure it wasnt constant spirited driving? i got around 200km's outa my first tank when i first got my R33 GTST. I gave it hell, everytime i put my foot down it went all the way to the floor. next few tanks i was able to get over 400km's as i started driving it normally, so the fuel usage lies heavily on how you drive the car Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/#findComment-2586430 Share on other sites More sharing options...
CHO50N Posted October 16, 2006 Author Share Posted October 16, 2006 Sure it wasnt the driving, I have had several Turbos before and even a 34 GTT and i was not driving any different to normal.

ZENNON Posted October 16, 2006 Share Posted October 16, 2006 fuel usage lies heavily on how you drive the car yeah i second that! i was amazed how much it affected it (not that i think that is the cause for your 200kms) Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/#findComment-2586984 Share on other sites More sharing options...
GTR32GUS Posted October 16, 2006 Share Posted October 16, 2006 Check your AFM Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/#findComment-2587067 Share on other sites More sharing options...
mad082 Posted October 16, 2006 Share Posted October 16, 2006 firstly, how much fuel are you talking about when you say a full tank? there is no point saying 'full tank' since when some peoples gauge shows empty it has used 45L, others 55L. convert it into L/100k's. e.g. if you get 217k's to 50L you are getting 23L/100k's. if you only used 20L/100k, and if you only used 40L thats 18L/100k's. also, what mods does the car have? that could be the key to answering your problems. otherwise it may be either your AFM or o2 sensors.

ookami Posted October 16, 2006 Share Posted October 16, 2006 yeah mine has now started the same problem, I don't drive mine often (maybe once a week if I'm lucky) so a tank lasts a while, but i manage about 260km out of a 40L so i get about 15~16L\100km. When i first got the car i got almost 560km out of a tank (not sure how many litres, was a damn while ago) on the highway coming home from the compliancer. Whats th best way to check if its afm or O2 besides get new ones?

mad082 Posted October 17, 2006 Share Posted October 17, 2006 ookami: you said you got 560k's out of the tank on the highway. you always get better economy on the highway. 15-16L/100k isn't that bad. i used to get that out of my magna. if i took it easy i'd get 14.

ookami Posted October 17, 2006 Share Posted October 17, 2006 yeah i mainly drive on the highway now though (about a 40km drive to the city at 100km\h to get that 16L\100km Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/#findComment-2589301 Share on other sites More sharing options...
GT-R32 Posted October 17, 2006 Share Posted October 17, 2006 I get 12.5 around town! ~360kms from ~45L (as much as I can fit in at the time for the last three tanks). Bloody stoked with that consumption, I expected around 14-15L around town. Worst I have gotten was 350kms out of 47L which is 13.4/100kms. Still bloody good given performance for around town driving IMO.

N1GTR Posted October 18, 2006 Share Posted October 18, 2006 Before mine was tuned it was going through a tank every few days, it was really bad, but after the tune its fine, average 350-400k's per tank, or way less at trackdays etc ovbiously Have a check of: AFM's if your not running a MAP sensor ECU (which it doesnt sound like you are) 02 sensors Spark plugs An idea would be to use a MAP sensor ECU, i was advised to do this, and im very glad i did, tuning was a bit more expensive, but the AFM's arent used anymore eliminating that from ever being an issue - something worth thinking about EDIT: Also i didnt think an ECU would be worth it for how my car was back then, it paid for itself VERY quickly, but aswel as that, the timing was all fixed up, and there was no more surging - just power where-ever and when-ever Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/#findComment-2595603 Share on other sites More sharing options...
GTRgeoff Posted October 18, 2006 Share Posted October 18, 2006 For some reason mine eats O2 sensors and runs super rich with them plugged in so I run them unplugged. Might be worth giving that a try. See how it goes after new turbos, PFC, 044 and 600cc injectors. As it is now it pulls 260rwkw on stock computer with steel wheel stock turbos.

I get between 16-17...... no real difference on the highway (I have got as good as14.6) as it still sucks the juice car is basically standard Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/#findComment-2595921 Share on other sites More sharing options...

I found my last gts-t wasn;t that bad on fuel even tough i was running 270 degree cams and pushing 270rwkw, did have a map sensor ecu which as said above may make a difference.

My stock gtr is worse LOL yeah it's a gts-t.... pig on fuel, but you get that i have done a lot better with this tank. Cruise back from cooktown to cairns sitting on or around 100-120kph and then a few runs around town and the light has just come on. 445kms so far. that is a little better Link to comment https://www.sau.com.au/forums/topic/138840-r33-gtr-only-200kms-to-a-tank/#findComment-2599059 Share on other sites More sharing options...
