Haven't had a chance to change the O2 sensor yet. But cleaned the TB, PCV, AFM and air box temp sensor. Idles smoother and seems to have more urge when I reach the 3000rpm mark.

The other factor that maybe contributing to bad fuel economy was my wheel alignment was way off. Had the wheels aligned this morning. Front left wheel was toed in by 3mm! It was actually visibly noticeable - I just never cared to look.

Hi Fellas,

I'm going slightly off topic. But the car is still an N/A and a Nissan :P

Mrs. and I recently bought an N15 Pulsar 1.6L Auto sedan (granny spec??) as a our runabout/train station/shopping center/park anywhere kind of car. Car is 100% stock and has 170,000km on the clock.

I've been driving it lots lately (to work and back ~100km round trip) to get a proper grasp of the fuel economy as I've suspected the car is guzzling fuel, as we all know short trips are a bad gauge of measuring fuel economy - mainly used to go to the local train station/shops.

My route is mixed urban and freeway driving. I'm not too happy with the fuel consumption. I'm getting around 9L/100km when intentionally babying it and 10L/100km when driving "normal" (not thrashing it).

I thought this kind of car should be using around 7 to 8L/100km - being realistic, I don't believe the figures posted by Redbook (quoted combined 6.2L/100).

I've made sure tires are inflated to the correct pressure and did a an oil (Nulon Semi-Syn 10w40) and filter change. I'm currently running the car on Shell V Power every fill in the hope it will clean the engine.

Just wondering is anybody out there is having the same consumption with the same car or a car with a similar sized engine, 1.6L Auto.

For comparison purposes my Lexus IS 2.0L 6 speed manual gets 9L/100 and my R34 2.5L auto gets 11L/100, for the same route....

I realise this post is a little bit old, but what I am going to say may help others and contains some generic info. those 1.6l engines with an auto bolted to them are slugs. They are fine once they are up and moving, but take a bit to get going (I used to own a n14 version). But they should get reasonable economy as long as you aren't in stop/start economy (even then you should be in the 8 to 10l per 100kms).

I'd definitely be looking at the o2 sensor if you haven't gotten around to it yet. The other thing to check I'd how long it takes to warm up. When I got my n14 off my sister, it would sit on cold on the highway and would only come up to warm going up a hill. It was also sluggish and used more fuel than it should. I changed the thermostat and it made it run better and use less fuel. I can't remember what sort of economy I got though.

On the fuel economy front, my old daily (vt Commodore with close to 300,000kms on it) was getting about 8.7l/100kms (pretty much all highway driving). My new daily (2002 1.5l mirage with over 250,000kms on the clock) gets about 6.3l/100kms with normal highway driving. Got 5.7l out of it when babying it. Would get marginally better economy out of it on a different trip than to and from work, since there's a few hills that require dropping back a gear or 2 (one that's back to 3rd at 80kmh for just over 1km).

    • 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?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
