but, here is what I did
New from the factory, put on 500 Miles, then changed to Mobil 1 5w30, changed again at 1500. After that I changed it every 3000.
Opinions seem to vary on engine break in, here are some of the things you will commonly hear:
"Don't let it idle, you want movement and varying pressure in the engine so that everything begins to seat and/or settle."
"Don't maintain constant speeds, try to slighty vary, even if it's only 5mph variance. Never use the Cruise Control."
"It's important to coat an engine with Organic Oil first, then switch to Synthetic."
etc.
I don't know how accurate they are, but enough people have said them to me, so I tend to follow them. I also consider an engine in it's break in period for the first 2500-3000 miles. I'm a huge fan of early/often oil changes. You can't hurt anything but your wallet by doing this. Also, pull your plugs and check them for fouling/deposits and proper gapping. Check your filters, keep an eye on your fluids, basic stuff really. Honestly, I think if you get into the habit of doing these things, you are less likely to encounter any problems.
Another thing is don't mash the pedals, learn to use them smoothly. It's all about the load on the engine, pushing to the floor is rarely the answer.
good luck, enjoy your car.
