Gas Mileage?

thats normal.
1) winter fuel is blended not to freeze, you lose mileage and performance
2) you spend about 4-5x longer trying to get the car to a warm temperature, if it does when its that cold
3) cruising on the highway at a constant speed is that your normal driving to compare it to? i doubt it, comparing city and highway mileage are two very different things. 4) when everything is that cold, everything has to work that much harder to get moving, so you've got more resistancce in the engine oil, tranny fluids, diff fluids, wheels, axles etc.

besides the car naturally does not get good mileage.

summer time the best I ever saw was 500 some. That was driving on a flat highway, with a slight tailwind, and NO boosting (not even passing) because I wanted to see what I could get.

I am glad you started this thread because I just finished my first tank since I got the car back from the bodyshop/painters and I racked in around 270. There were some good spirited runs in there, and also I have remote start so the car runs for around 10 minutes warming up before I even get in it.

Running redline heavy shockproof in all the drivetrain has a parasitic loss especially when its below -15C out. it was -26 today, and the car did NOT like starting. I'm getting a pad heater on wednesday to help get the block warm. Synthetic oil is a must if you aren't already running it.

Nick, what are you using for engine oil when its cold out?

i live in vancouver, so my winter can't be compared to yours. i run 3 different oils, basically whichever is cheapest at the time. mobil1 0w40 euro formula, lubromoly synthetic 5w40, or shell rotella t synthetic 5w40. i use them all year long.

i should mention i've never got more than 370km's to 46L, typically im in the 340ish range. i'm all city, no highway, and i'm not friendly on the foot.

Weather seems to play a bigger roll than i thought it did, i guess my original numbers aren't really accurate, i'll have to see what i get in the summer again. I have a feeling it will jump right back up to mid 300's for the city in the summer...

im not sure with the GTiR, but with my R32 GTR its not recommended to use the redline heavy shockproof as it eats the copper in the clutch... this might be worth looking into for GTiR's as well since they are affectionately refered to as the baby GTR... im sure they share more than just the nissan name plate and the attessa-ets

a clutch doesn't sit in oil my friend

and if you're talking about the transfer case, the transfer case in a gtr is completely different to a gti-r. the gtr case uses atf and is a hydraulic based clutch system. the gti-r is a viscous diff all mechanical requiring a 75w90 gear oil.

thanks... im new to the whole GTiR and learning as i go... better to know now than later when i have one i was just passing on what i know about the GTR's i thought there might be some other things that are common between them

Ive never gotten more than 250 to 275 a tank. Makes no diff if i drive hard or not. But i do have bigger injectors and a heavy foot.

i got just over 300 on my first tank!! the cars been on the road since 4pm yesterday!!!
what gas is best Sunoco 94? or Shell V-Power
i always liked V-Power but then i always just drove NA.. recommendations?

As high an octane as you can find at the pump is probably best, although with the greater percentage of ethanol mixes in fuel now, I'm not sure if it's better to go with, say a 91 octane with 5% ethanol than a 94 octane with 15% ethanol (only hypothetical numbers). Anyone have an opinion?

Oh, and I get about 290 km to ~45L in the cold winter, all city with the odd +7mm Hg boost.

Ty

shell in canada is garbage, anything that offers a 94 octane i would use. isn't shell in canada at 91 oct?

thats what i figured too... apparently Shell 91 has no Ethanol Added! so that makes for a better fuel!, i used to be a Sunoco 94 guy... but then i tried and tested both fuels, and Shell came out on top with almost 100KMs more per tank! granted it was an NA 240 with 220kms but i then tried it on my dads 4cyl 626 and i saw an improvement, and also my friends 87 Supra Turbo.. he went from 230~ to about 250~ i know its not that big of a deal but in times like these every km counts!

It Doesn't matter how I drive it I get 250 no matter what!! maybe a 50 km differentiate.

have you changed your diff fluids? also i'd replace your o2 sensor, cap/rotor, and plugs to start. else you might want to check if your thermostat is stuck open, you may never be reaching operating temps.

All of the above,I have been meaning to do and today is as good a day as any thanks nick.
Are most of those parts nx2000 compatible ie "Partsourceable"

cap n rotor i took of a p10 infinti g20, i use ngk bkreix8's for plugs, but if you're pretty much stock bkreix7's will do. and the 02 sensor i'm not sure about, i just purchased the gti-r specific one.

where did you get the sensor?

i ordered direct from nissan

i dont know about others but ive been told huskey is one of the better...they only offer 89 91 and 94...and its got the ethanol in it! my car loves it compared to chevron (with techron), thats the only two places i have for options here in town! but husky is good stuff! oh and i only get a max of 300kms per tank....its a pig, and i thought i was running rich but i pulled my spark plugs and everything out and its all good! so they just like gas is all! and i only run 94 octane, expensive when you have a lead foot that enjoys the attention when ure the only one in town with a gtir!

oh and nick do they honestly stock that perticular cap in town at your napa, westcan, lordco? i went looking for one and they said they would have to get it from van! the only ones they had were for a 6 cylinder

cap 22162-53J00
rotor 2215754C01
I guess it can come off any car with a sr20de engine. nx2000, p10 infiniti g20, sentra with a 2.0

I agree with crissymiller. Husky/Mohawk 94 octane makes a world of difference. The crappy 91/92 octane just doesnt cut it for these cars. Mine is super grumpy if its not 94, and its 10% ethanol blend too.

I drive a lot of highway, and since changing fuel filter, cap and rotor I am getting about 10.5 L/100km... but again mostly highway. O and I live pretty close to the border so I go down and get gas in the USA when I can... saves about 25% but only 93 octane. If not then petro canada 94 octane it is.

petro isnt that great but its better than any lower octane! i just know from what we have in kamloops that husky is the best...all the right hand jdm cars here use it!

Just got my R on the road, and have been shocked by its consumption. Makes plenty of sense to me now, as I'm still in that "only GTIR in town" phase, so I'm boosting a couple times a trip, but around 50 clicks on a quarter tank! This car is gonna break me isnt it? Love it too much though.

Nah, thats just the gauges though. doesn't move for the first 40, then goes down a quarter in 10km. Normally i say if its at half, with 150km you are doing alright... And yes, it will break you.

well if u want power then dont complain about fuel consumption. compare any other 300hp car, you are in the ballpark of similar mileage.

I have only managed to see a max of 450km on one tank on the highway. Doing city driving I ussually get around the 300km range.

You are also in alberta though, your highway driving is insane. you rip it at like 130 everywhere you go. Drive at 110 and your mileage will be better. I'd still rather have a car that eats mustangs and the likes then worry about mileage.

i've done datalogging and 90-100kph is the most efficent speed in 5th gear. Mileage drops off as you pass 100kph, in my particular car the most I can squeeze out is 7L/100km at 100kph
