Does anyone know what the break-in point on the engines is? I haven't been redlining it or anything. It has almost 700 miles on it. The dealer said fluctuate the speed and how you drive it for 5 to 600 miles. Or is it at 3,000 miles after the first oil change?
Zero, with today's technology and methods used to prepare engines for assembly, they don't really need a break in period. The engines of today are pretty much broken in at the manufacture before they leave the assembly line. All engines are test fired before they go out, and modern engines are broke-in in about the first 10 minutes or so after first start up. This doesn't mean it's OK to run WOT from the moment you drive it off the lot. It just means to drive it like you plan to drive it.....period. Like anything new, just use common sense and you'll be OK.
True, the owners manual may say something to the effect of driving it easy and varying the RPM for the first 500 miles or so, but don't most people drive that way anyway. The break-in procedure is a carry over from days past when it really did matter. But manufactures keep it in print as a CYA kinda thing. With that said, I like to replace my original oil at about 1000 miles on a new engine. It used to be 500 miles, before using synthetics, and although many cars come new with synthetic oil it's an old fear of mine stemming from the old day's when cars did need a break in. Rings used to take 1000 - 1500 miles or so to seat. So now I replace my original oil with synthetic at 1000 miles just to be on the safe side.
Some may replace the original oil with fewer or more miles than I do, but there's no right or wrong here, just do your thing.
But remember, more importantly than engine break in is everything else. The brakes need to be properly seated, in an AT car the tranny needs to be broke in, in a manual the clutch needs to be broke in. - Dan
