Mack: Re-fuel on these big 3.0 straight sixes, I just cannot believe what these girls do to the gallon, I admit whole heartedly that I drive like Miss Daisy [62mph down the A14 & never over 70mph, change gear at 2500 rpm.....I just love the lazy grunt of these big sixes] and my computer says 40.3mpg even allowing for 'computer error, high 30's & low 40's is astounding!
