Oh yeah, since people have been asking what I do to get 17-18 mpg...

Something I just thought of that might be good info to share is that I use Shell Rotella T oil in my Xterra. You can pick it up cheap from Walmart or most auto parts stores -- about $9 to $15 a gallon.

I use this oil in all of my vehicles, including a 2003 CBR600RR and my 2004 CRF450R with great results. You can also change it more frequently than normal if that is your routine because it is so much less expensive.
