New Car engine break in.
thanks!
You will get two different opinions on this, but I would do what ever the owners manual states.
Me personally having been a mechanic my whole life I drive them real nice and easy and slow the the first 500 miles and stay under 55 and vary your speed no ******* it and no WOT runs and then change the oil.
Then drive her 60-65 as a max to about 1200 miles and you can get in it a little here and there but not for long.
After that drive it normal highway speeds fast as you want but try to minimize WOT runs till 2500-3K miles.
This is how I do them on my personal stuff and they dont use oil they have lots of power and no piston rattle as the miles rack up. New cars a huge investment so I prefer to not beat on them until they have a few miles then its game on.
Our crate LS3 was installed and then car was driven straight onto the dyno and run in.
