I can get about 630km out of a tank. The warning light comes on at 47L (580km) and I can get another 50km before I panic and fill up. Even then there is 4 to 5L left in the tank. I do mostly highway driving and keep my speed around 120km/h. If I go faster I find the fuel economy really starts to go downhill. I use 91 octane fuel because I do notice a difference between it and 87 octane fuel. I get a little better economy and throttle response.

Driving with your tank below a 1/4 of a tank is REALLY bad for your fuel pump guys. Keep that in mind when it cathes fire and explodes.

dude i drive around with $5 of fuel in my car most of the time(exept on long trips on the highway and when ever i get money to put it in. i find the car goes alot faster when the fuel tank is nearly empty.. i have never heard a fuel tank catching on fire because of there being lack of fuel... probably in a drag car when its doin a huge burn out and the fuel line catches on fire, and there is alot of vapour in the tank, but man these are protege's...

I live in US, so miles/gallons here. On my first two tankfuls (around 12.5 gals each), I got about 23.5mpg. This was 30% city driving, 70% busy highway driving around 65 to 80mph.

Last weekend, I put 870 miles on my car going up to Maine and back, and I got around 26-27mpg with 90% highway driving around 80mph.

I used cruise control a lot last weekend, so I can't help but think that the mileage difference is because cruise control drove smoother/most efficiently? (automatic tranny here)

Another thing is that it could be that my first two tankfuls were during the break-in period, which could be less efficient? I just refueled today and I am looking at a week or so of 30% city 70% highway driving (commuting to work) again, so I'm curious to see whether my mileage is gonna go back to 23-24mpg.
