Just to dispel the notion that Z's are hard on gas, I just went 548 km on my latest tank of gas, and the gas light didn't even come on.

I do mostly 75% highway driving, but I took her out Sunday on the backroads and did some fairly aggressive driving, lots of full throttle to redline.

I've been averaging about 500 km a tank till now but my mileage seems to be improving as the weather warms up.

I've only got 4800 km on her so far, so I think the Z is probably going to match the mileage of my 2k2 Max 6-spd.

 

SWEET! That means break-in in 4 tanks!
Just waiting for street sweepers to get rid of all this sand on the roads... still sitting at 32.5km
