So I have heard there is no 'break-in' period 'required' but read in the manual that I should wait until 600 miles to 'prolong the life of the engine'

At the end of the 600 (soon) should I do a full oil change, has anyone else? Trying to decide whether or not I should do my first change REALLY early.

You don't have to do your oil change early, just not to push the car hard until it breaks in. I forgot where I saw it but I read it was more like 1000-1200 miles for the break in period for the car. I would give it around there before pushing harder.

I thought I was almost there, but now you're telling me I'm halfway to almost there lol. I'll wait, I am scheduled for Paint Protection Monday 6-7 anyway

If the manual says 600 miles (1, 000km) then it should be safe to go with that number. If you want to be on the safe side, you can wait until 1,000-1,200 miles before it's fully broken in with the towing and everything.

I broke in the car how I drive the car, and have had zero issues. Some days it's a family car, some days it's a race car. My daughter prefers sport mode, so we did dabble during the first 1000 miles, but I did not push the car like I do now (at 5000 miles).

No redline shifts, but don't baby the car either. Drive the car like you plan on driving it, and you'll be fine.

Same..even in normal traffic..it's pretty impossible to stay under 4k RPM.. shift happens.
