Main Question or Discussion Point

I expect to be shot down in flames but I don't mine one bit.

I have just done a bit of a drive in my 28 year old Nissan Bluebird Wagon about 10% city 90% HWY....NO Fancy EFI systems or direct injection here just a plain old carburetor running slightly rich at idle.

I just did a rough distance calculation on whereis.com ...308 Km on 18.23L of fuel that's about 5.9 L/100 km and have 2 other people in the car and with tools and baggage.
I will fine tune the mileage later on but I filled up at Warnbro then to Subiaco to Kenwick to Armadale then filled up at Wagin.
I put in 1/2 a tank of 98 octane as well but this would not account for such an increase in mileage.

Also the Elevation of Wagin is 303 m and the elevation of Wanbro is 20' so I was going uphilll slightly as well over the journey.

I have receipts which I can scan later on if needed.

My car is rated somewhere around 11 L/100 km on the HWY.

But if its impossible then how did I do it?

Poll options
1. False=You cheated some how.
2. True=I believe the figures.
3. A 20L jerry can topup.
4. Fill up half way on the trip with cash.
5. Would MythBusters buy my car and test it.

I will be doing some more trips soon and will keep more records.

I know I need to pull the engine out and put it on a test bed but at the moment its the only licensed car I have.

I guess I would need a professional 12 V video camera and mount it so it had a view of the road and the fuel cap and could record for length for 14 to 16 hours or maybe a cheap web cam to start with.

1. 5.9L/100km looks achievable with some effort in a car like the one you describe.
2. 11L/100km doesn't look right for the fuel economy it is rated for. If this is the car, it is rated for 8: http://www.eurodb.com.au/used-car-Specification/NISSAN/BLUEBIRD/GX/1984/JAE/ [Broken]
3. This is nowhere close to the quality level required for serious discussion here.
4. We've been over this. It didn't fly two years ago and it doesn't fly today. As we told you two years ago, your methodology needs to get a lot better. It is time to stop humoring this.

Locked.
