Out of interest...

What mods have you guys got?

What petrol do you fill 'er up with?

How far do you get on your tank?

Auto or Manual?

City or Highway driving?

I've got a catback Impul Exhaust, Impul tuned ECU, K&N Air Filter.

I've been using BP ultimate extreme or whatever they call it.

Averaging around 450km's to a tank.

Auto

50/50 City and Highway

I'm currently getting around the 13.5L/100km. It's a bit higher than others have posted, but I've only had the car a few weeks, so most of time, there's a bit of hard driving going on:-)

Just got 648kms out of the last week n a half! :)

Driving to Byron Bay sitting on most speed limits I got 12.3 km/l or 8.1l/100km. Around town I get about 9.6km/l which is excellent from a 3.5l engine and 1550kg - results due partly from the low Cd of 0.28 and zero lift aerodynamics

Does seem quite high Frank,

I'm sitting on around 9.4km/L in sydney traffic. That's taking it quite easy though. But I love it, 70km's a day and the guage only moves a notch or so per day.

Cheers

Bobby

I need someone in inner west good at Skyline/350Z to check it.

I have regularly been getting low 7's according to the computer over the past couple of months, all city driving, bumper to bumper, barely moving an hour each way. Is this where it should be, or is it too low? When I do get to drive on an open road (i.e. late at night), the economy is much better, around 10ish, so I'm assuming its just due to the traffic.

This is an interesting thread...

What driving styles do you guys use? If manual, what RPM do you shift at.

Also, what can we do (besides babying the throttle) to remain as economical as possible when not fanging around? Any good fuel economy mods?

Has anyone used anything other than 98 RON? The Yanks use 91 and seem to run fine?

US fuel is different as it has a different rating system. Off the top of my head I believe that 91 is close to the 98 we use.

My car is achieving fantastic fuel economy, with average klms per tank getting up in the very high 500's (without the fuel light glowing when filled). I recall one mid to high 600's tank, but that tank had a few fair few highway klms. I would love to do an open road trip as I am sure 800 could be possible.

I am fairly good, maybe baby it a little too much at times. I find that it does not need a lot of revs to get the job done (however do not under rev). I must look at my average shift points, as I do it more by sound and feel than anything else.

Hey Graeme,

Yep I would agree, and am getting pretty much the same. When i had the auto i drove from Sydney to Canberra, reset the fuel computer and it said on a full tank i would get 800 and something, so your comment is spot on.

Ahh, I didn't know that about US fuel, but Wikipedia to the rescue:

In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States, Canada and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-92 in Europe. However most European pumps deliver 95 (RON) as "regular", equivalent to 90-91 US (R+M)/2, and even deliver 98 (RON) or 100 (RON).

According to this, US 91 RON is close to our 95-96. Interesting.

Are you doing City kms for the high 500s??

Just a question guys. How many litres to fill up?

There seems to be a huge range in fuel economy and it's all better than my r34gtt which gets 300klms per 50 litres.

      Neostead, I'm looking to have a custom surround done that also has a slot for a fog light. Would you be willing to create a 3d model I can buy or create and ship me the part or even provide/sell the current model for me to modify? Cheers

      MLR's Bogan cruise ship

      By The Bogan · Posted

      Did some maintenance on the MX5, did the engine oil and filter which was uneventful, then I drained the coolant to put in the new reservoir and a thermostat, reservoir took 5 minutes  The thermostat, well that took.........3 bloody hours, what a job, the issue was the 3 bolts holding it on, one was easy, 2 were hidden and required a few 1/4 drive extensions, 1 more than I had, and a 1/4 swivel, which I also didn't have, and a good amount of playing contortionist  Getting the 2 unseen bolts back on was a time consuming nervous nightmare, as I couldn't see where they went there was alot of stabbing and hoping for the best, trying to line up a 8 mm bolt straight, which you cannot actually see or get a hand in there, with a 1/4 swivel in the mix was a nightmare Anyways, it's done now, all burped out, and run up to temp a few times, happily no leaks thank Jebus After the thermostat fiasco I decided I need a few mental health days away from tools before doing the rest of the servicing on it As for the Dunnydoore, it had the aircon regassed and it has a clean bill of health, thinking about taking it out on Monday for a cruise down the coast to look at some houses if weather permits

      Duncan's Race Car - The Most Overdue Build Thread On Sau

      By Duncan · Posted

      In other important race car news, instead of fixing the race car I changed the crank seals on the chainsaw, because wood burner Some damn tight (and lock tighted) m6 head bolts Who knew plastic crank cases were a thing! Quick tip, don't trust the youtube videos that say you can pull the old seals out with the head on in a husky 440e...not true, their crank seal tucks in behind the cover both sides. I'm not sure I'm a psychopath, but these things are damn loud....hope I can put all the bits back in the right place    Happily, it is now back to turning fallen trees into a combination of firewood logs and wood chips....just need a clear day to get into it properly

      Don't forget to make sure the tank is full to the brim before you try to replace the fuel pump too, that is an essential step.
