如果要专业些，读下文：
Updated 10/2012
New generation TDI's with Common Rail/DPF/SCR and those with DSG
transmissions
Rules that apply for the life of the car
-When the engine is cold (below the first 3 white marks at the base of the
temp gage) rev the engine to at least 2,500 rpms.
-When the engine is warmed up (above the first three white marks) Rev the
engine to no less than 3,000 rpms.
The reason for this is to keep the turbo on boost, clear the VNT guide vanes
and apply firm pressure to the rings for optimal sealing against blow-by
gasses. The rings need the boost to seal since its a turbo charged engine,
babying the engine is detrimental and will lead to issues with compression
if done so for very long.
-Keep rpms as close to 2000 rpm as possible when driving at a steady speed.
This promotes optimum temperatures for the DPF and keeps the engine in the
middle of its most efficient rpm range (1800-2200 rpm).
-Allow the DSG or automatic transmission to determine the optimal gear and
engine rpm. It knows better than you... Provided you have it trained to be
biased to the sport mode the engines shift points will occur at the ideal
ranges.
Redline is defined as the maximum rpm allowed by the engine, in the case of
all TDI's it is 5,100 rpm. The maximum physical limit of a TDI engine due in
part to it's short stroke is approximately 8,800 rpm (this is when you will
throw a rod or damage a piston, this rpm is not possible unless you force a
downshift into 1st gear while driving 80mph)
The instrument cluster shows a red BAND starting at or around 4600 rpm, most
owners will find that very little power resides beyond this point due
mostly to the ECU reducing fueling to respect the smoke map.
Adaptive Transmissions (DSG), "adapt" based on how you apply the power with
your foot. Over time they will modify shift patterns with a bias to a "Sport
" mode. Train the transmission to shift as close to the recomended rpm
ranges below.
When your engine was first produced the motor was placed in a test cell and
"Run-in" by a computer run dyno. The motor after the run-in was DRAINED OF
ALL ITS FLUIDS (Oil, Coolant etc), the filters were replaced and a unique
break-in oil was installed to promote a proper break-in once installed in
the car as well as to protect the engine from corrosion during shipping to
final assembly.
The "Break-in oil", YES VW does use a specially formulated "Break-In" oil
formulated under an internal "TL" specification and produced by Fuchs. The
oil is a group IV synthetic 5w30 formulated to comply with the LowSAPS VW507
.00 requirements as well as the TL specifications for break-in. The oil is
intended to allow a controlled rate of wear while protecting the engine and
allowing the internal parts to seat proplerly during the engines first 10,
000 road miles.
First 1,000 miles
Keep rpms below 3,800. Avoid steady rpms. Frequent firm (75%) application of
power is strongly recomended up to a maximum engine rpm of 3,800. Avoid the
use of cruise control so that you naturally fluctuate the power with your
foot.
DO NOT CHANGE THE ENGINE OIL UNTIL 10,000 MILES!
1,000-5,000 miles
Use the full 5,100 rpm power range. THIS DOES NOT MEAN DRIVE AROUND AT 5100
RPM! This DOES mean to find the rpm range where your cars best power resides
. Most owners will find that the best engine operating range to be between
2000rpm and 4200 rpm for the purpose of acceleration. At all costs avoid
using full throttle below 2000 rpm the ECU will attempt to prevent you from
applying full power in this range, work with it and don't request it with
your foot.
Continue to avoid steady rpms and avoid the use of cruise control.
occasional application of full throttle (100%) is recomended to help seat
the rings. City driving is ideal for breaking in a TDI due to frequent stops
and acceleration. DO NOT CHANGE THE ENGINE OIL UNTIL 10,000 MILES!
5,000-10,000 miles
Use of the cruise control is ok at this point since most of the initial
break in has occured. Continue to use occasional full throttle accelerations
to continue to seat the rings. You will notice the engine become slightly
louder during this phase due to less friction from the engine breaking in (
normal for a diesel to become louder under lighter loads). If your going on
a long drive and you are using the cruise, every so often step on the peddle
to accelerate up about 20 mph then coast back down to your preset speed.
Your first oil change is due at 10,000 miles DO NOT change it early! Oil
analysis supports 10,000 miles as being realistic for a first change
interval. Wear metals will remain at safe levels during this entire first
interval thanks to the initial run-in and flush at the factory before the
engine was installed in your car.
10,000-60,000
This is when the rest of the break in occurs. The engine from the factory
will check out with about 475psi of compression pressure out of the crate.
It will take at least 60,000 miles to reach the peak pressure of 510 psi.
For the most part once you get to 10,000 miles your compression will be
around 490 psi meaning that most of the break in has occured.
60,000- and for the remaining life of the motor
The owners have followed the advice above and do not have any oil
consumption issues. This also means that with the higher pressure the engine
is more efficient returning optimal fuel economy and reduced smoke output.
I am still of the opinion that if possible use a LowSAPS 5w40 instead of the
5w30 oils ie Mobil 1 ESP 5w40 formula M (MB229.51, .6 Sulfated Ash)

60,000-the life of the motor
The engines I have seen so far using a 5w40 oil are maintaining 550 psi of
compression pressure with over 200,000 miles on the odometer. The owners
have followed the advice above and do not have any oil consumption issues.
This also means that with the higher pressure the engine is more efficient
returning optimal fuel economy and reduced smoke output. | j*********n
