[Closed] Do cars lose horsepower with age?

CaptainFlashheart · 2010-10-04T19:54:03Z

Come on then STW Mechanical Minded People - Does a car lose horsepower as it gets older? This is the subject of a long running argument with a friend. He asserts that his car will have [i]more[/i] power as it gets older as everything will run smoother or something. I assert that this is a load of loblocks. So, what's the truth?

Another FYI, compression can increase with engine age due to better cylinder ring sealing (after break in) but more importantly due to carbon build up on the cylinder head combustion chamber.
