After spending $40,000+ on a new Challenger, I am leery about his "hard acceleration/hard deceleration" advice. The only thing that I agree with is a quick oil change to remove metal filings.
Ahh, well yes, I guess I meant to say 4-Stroke ! Since I'm not a mechanic &

/or very knowledgable, are the V8's.V10's,V6's and even 4 cylinders =4-stroke machines ? I didn't quite think Aggressive break-ins are the way to go either. I mean with all the testing that must or does go on I would think the manufacturers would have told us if this above stated method would be the proper way to break -in ! In fact does anyone know what the race car drivers/teams do for Nascar or Indy types or are those race engines "pre-Broken in" before dropping in ???
