Yea I'm picking up my 2013 in the next few days. I was told to keep the rpms below 4,000 for the first 3-5000 kms. Is this a good idea or over kill?
You'll get various answers to that. Some say push it hard asap, others say baby it for 1200kms.
I think you should baby it the first 20kms, then go to 3k rpm max for the next 100 (normal driving), then start to up the rpms gradually, and start to push the beast a little... little by little open her up, but do not hold for long. At 500kms, you should be hitting sometimes 4-5k rpm, by 1000-1200kms you should give it full rpm swings, but just one gear or two, not the whole 6. By 1500rpms i think it's pretty safe to give it hell.
Engines today don't really need break in... the cylinder bores are crosshatched, but it's very fine.... and the rings have to seat, so that's why you should push it before 5000kms.
If it were a problem, they'd break in the engines at the factory... so yeah... breaking in is, in my opinion, a little over rated, especially for large production cars that aren't modded.
forgot to mention: do not hold steady rpms, do not idle for long periods and let the engine warm up fully before the pedals hits the carpet.
