Have been getting only 20 miles / gallon from my 93 r33 gts-t 4door auto. Has new NGK Iridium plugs and I use BP Ultra and 10 pounds boost.

Bought the car and had them up the boost to 10lb b/4 I took possession of it, so I don't know what the fuel economy was b/4.

Many people on the net say they get between 26-30 mpg so I was a little concerned. Had a mate of mine who works for one of the Nissan dealers check it out and all the data came up ok.

He said that it must be a combination of being an auto, the upped boost and a bit of a lead foot that is contributing to the low fuel economy.

Just interested to know what some of you guys are getting economy wise.

Thanx

I have no concept of how good or bad 20mpg is. I don't even know how to do the conversion.

My car gets 14-16L/100km around town (usually just under 15) when running at 0.8 bar boost. At 1 bar it is usually just over 15. I am experimenting with a tankful on 0.6 bar to see how much fuel I'll save, if I gain another litre/100km I will set it to 0.6 when I'm low on cash and need to save money on fuel :D (I love EBC's!)

On the highway I get 9.5L/100km on .8 bar and 10.5L/100km on 1 bar. Keep in mind that this is with a lot of spirited overtaking. It's the main thing that keeps me awake!

Man I hate this L/100km crap, makes it really hard to work out how far you can go on one tank on fuel. Sod it, I'm going to start doing kilometres per litre too, starting right now.

14L/100km = 7.14km/L = 428km per tank (fill up around or before 400km)

15L/100km = 6.67km/L = 400km (fill up ~370)

16L/100km = 6.25km/L = 375km (fill up ~345)

9.5L/100km = 10.53km/L = 631km (fill up ~600)

10.5L/100km = 9.52km/L = 571km (fill up ~540)

If I had been working off kilometres per litre instead of this stupid L/100km crap I could have saved myself from a huge stuff-up in refill planning on a recent holiday trip up north. I wasn't sure if I had enough fuel to make it to the next available servo on a round trip while in the area and ended up running around for an extra 60km that I later discovered I didn't have to (long story).

Thanx guys, I guess it must be my fault that this cars is an gas-a-holic.

I deal with metric measurement all day in my work and also relate things back to imperial often, but this litres/100 km has always pissed me off.

My daughters boyfriend is only 21 years old and knows perfectly well what miles/ gallon is.

Thanx again

how did u get 9.5/100km??  long highway drivin??

Actually, it was my gf taking the car up north from Sydney to Taree (about 300km) to visit relatives, then back again. Worked out to be 9.5L/100km when I did the mileage when she got back. We both then travelled back up the same day (she had to come back to Sydney for a job interview) and I decided to experiment with the boost pressure and set it to 1 bar.

I got 10.6L/100km for the trip up, and 10.4L/100km for the trip back. It was slightly worse on the way up because we had a little bit of city traffic to get out of before hitting the highway.

I guess I should have kept my mouth shut. Some of you guys are doing worse than me . Last fill up was 320km from 45litres, around 20MPG

Realisticly, I shouldn't complain as my Bedford van (work van) with a 400 Chev gets around 12 MPG. It carries a fair bit of weight though.

    • I've got a 2011 J50 that I imported six years ago. The unmodified factory AV system date and time has always been correct ( Japanese timezone of course ) up until last month. About two weeks ago, at engine start, the system wished me a happy new year ( in Japanese of course ). I can't think of anything that would make the system think that the date had changed, unless the GPS component has failed/reset somehow ? I checked the GPS reception in the system settings, and it can still see the satellites. Has any other J50 owner had this happen ?  It's no biggie, just annoying that it tells me the wrong date anytime I start the engine. 😅
    • Love following your adventures on IG, hopefully if you're still around in Japan when we visit again wouldn't mind going for a few beers with you (that's if you're keen on hearing how I hate Nissans).
    • ok so if i wanted to go 18's i would go for 8's  in front 30+ or 32+ off set at front and the back 9 would be ok? what offset should i aim for.. then can i do some  hunting for wheel rim choices..    If i get this - will this fit all around: Size: 18 x 8.5 +37 - n what tyres size tyre should i get for front n back?  
    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
