True !!! Only in theory BUT .... on the practical you can take the same car with the same wheels and even drive with the same driver and still get a difference of up to 1 litre /100km !! All depends on the way it's been run-in.
It is very true reguarding the diesel engines that they give its very best after 50 000km or even 70 000km on clock .... i was thinking of changing mine every 2 years !!! but i have a bike, a 1200cc bandit and don't always ride the civic and so hardly do 15000km per year (9375 miles per year) so i guess i'll have to keep it for 10 years if i wanna get the utter most of it
