Re: Engine Break in
There are several schools of thought when it comes to breaking in engines, everything from the "drive it gentle" to the "drive it like ya stole it" technique. T-56 is correct in stating that you should avoid synthetic for a few hundered (possibly 1-2K) miles to ensure that the rings properly seat and seal against the cylinder walls. The main things to remember are to allow the engine to warm up before placing it under high speed/load, and to vary the speed while driving. I'm not advising going from idle to WOT every other block, just do some city driving combined with light freeway. The first oil change is critical due to the fact that all of the unseen metal filings and broken down assembly lubricant will be in the oil, and you (obviously) don't want metal filings swimming around in your turbo or in the valvetrain. You can never change the oil too much during break-in, since contaminants will be in the whole system, meaning the cooler, cooler lines, turbo & lines, and oil filter lines. Better to do an extra change and make sure it's really clean vs have some problem down the road IMO. Most importantly..........Have fun with the new engine!:tup:
