No debating- it is. All modern cars I know of still recommend it in the owner's manual. Some (Toyota Avalon- a near luxury car) say not to take the car over 55mph over the first 1000 miles! Mazda simply asks to change speed often for the first 600 miles.Although there is debate whether or not this is necessary...[/b]
Numerous posts on this forum have proposed various breakin theories and methods. Those theories/methods mentioned are the same as those practiced since I was an owner of a 1963 Oldsmobile Jetfire (alchohol/water injected, turbocharged, 215 cu.in, 290 hp); followed by a '66 GTO, tripower. "Breaking in" is really a misnomer for a process wherein the bearing surfaces have an initial period of increased wear as the opposing surfaces 'lap in' to each other.Originally posted by Rainchild
so the question is... what happens if you do drive at the same revs over long distances? what's it do to the engine? does the car ever stop 'breaking in'?[/b]
