I have been averaging @18 miles per gallon driving mixed city and highway on my 06 RR HSE. This is according to the trip computer on the truck how accurate do you think this is? I'm not complaining but thisseems pretty high to me.

Anyone else getting this kind of MPG? It is not that far off from my old 5 series BMW inline 6 which got @21 MPG...

 

If you want to know exactly what sort of mileage you are getting, do it the old fashion way, you'll finf the computer is not very accurate.

 

My trip counter ispretty close to being right. it's always accurate within 5%. I get 14mpg mixed city and highway. I get 16-18 mpg with all highway miles.

 

my consumption meter tells me i average between 14-15 per gallon

 

its pretty damn close
