Yes, things have gotten better, but there is still a break in period, simply because all the parts arent' exact. For example, When building Boing 747s, one can be as much as 4 feet shorter then the next even thought they all use the same parts. This is becaues when you add up the tolerences for the millions of parts used, they add up.

Now, a car isn't nearly as complicated as a 747, but you get the idea. Not every piece is exact.

What I'm wondering is that I heard that the engines in the tc, as well as other newer car, were already broken in. Does it say anything in the manual about a break in period?

 

Someone here changed their oil and took pictures of the filters a little back. They said they saw no metal shavings in the oil, it looked clear and it was also thicker than normal oil. From what I understand, newer engines have magnets that collect the little shavings and do not need their oil changed at 1000 miles and some companies use special break in oil that needs to be left in the engine for 5000 miles.

 

Here is a good article explaining the how and why of breaking in:

It says to change the oil at 1K.

 

Just passed the 1K mark during my lunch break. Time to go drag racing! j/k

 

i called the dealer today , they said to leave the oil in the engine till i hit 3750, isnt that alot of miles for an oil change?
