Ok guys, im at about 165miles into my 10gal costco fill up and still have a bit more than quarter tank. Now, since my last fill up, this week ive done about 65% city driving and 35% hwy driving. I know this might not justify my costco gas fill up test, because on my 200mi per tank was with 80% city driving and 20% hwy, but it was still worth a shot! So far, so good. Ill report back with the final outcome.

It's probably my lead foot, and the ITB's making it hard to stay outta boost

A few pages back, it was pointed out that the NX should have a 13.2g gas tank, as per a few car info sites. I ran my tank completely dry last week till it wouldn't start. Put in maybe .5g in to get it started to get down the street to the gas station about 5 miles from my house, and filled it all the way up. I put in 10.5g. I still swear the NX does not have a 13.2g tank. No possible way! I know Ameen felt the same way, anyone else agree? And I only got 21-22mpg (~215 miles to the tank). It sucks... but now that I'm breaking in this new clutch and staying out of boost right now it's doing a little better. We'll see in a few days. Just food for thought.

x2.. My b13 started running out of gas as soon as I pulled in to a gas station and when I put gas it only took 10.5 or so gallons (I have it written down, can go and look lol) just yesterday I filled up my new b14 for the firs time and as soon as the gas light came on I put gas... 11.4 gallons. No way in hell the nx and b13 have 13.2 gallon tanks lol
