ENGINE- T
he engine, it's made up of a lot of parts that move up, down, and around in close quarters
with nothing between them but a very thin film of oil. All of these parts are machined or forged according
to what are called "manufacturing tolerances"—basically, a margin for error. Not much margin, but these
engine parts will inevitably have microscopic high and low spots on their surfaces. In the cylinders, for
example, this helps to explain why oil consumption can be higher-than-usual during the break-in period.
TRANSMISSION-
Same is true for transmission gears and others. It takes some wear under load for
those little, high spots to get worn nice and smooth so they fit just right. Run the engine too hard before
this happens, and one or more of those high spots might rub through the thin film of oil, resulting in metal-
to-metal contact. That generates a lot of heat; things get warped and, well, that's not the sort of thing that
leads to an engine leading a healthy life.
TIRES-
When tires are being made, they're coated with a special lubricant so they don't stick to the mold
when they're finished cooking. It takes a while for this lubricant to wear off, and until it does, the tires
won't give you the kind of grip you'd expect from a high-performance tire. As well, if you floor it or hammer
on the brakes, those same lubricants can cause the tire to slip on the rim, affecting balance.
BRAKES-
Be especially careful for the first few stops—pads and rotors may still have residue from the
manufacturing process on them, and they may not give the stopping power you're expecting. After that,
avoid hard braking for at least the first 500 miles. By allowing the heat experienced by the pads and rotors
to build up gradually, you're giving the pads a chance to put a consistent layer of what's called "transfer
film" onto the rotors: the key to smooth, effective braking performance over the long term.
