That depends on how well it has been taken care of, what kind of shape the engine is in, how old/ how many miles it has on it, if it's got all the proper fluids in the correct proportions, etc. If all that is good, then nothing if you only do it every once in a while. But no matter what kind of car you drive, the harder you push it, the quicker things wear out. That goes for cars that are built for racing as well, they are just built stronger. Like I know when I top my car out I tend to burn oil up and I know things on my 91 are getting worn out.
