Diesel - run in tips
 
I'm eagerly awaiting my diesel GC, any tips on a good run in procedure?

Hi there, you can start by letting the engine heat up first before you do your break in (if by run in you mean break in). Then when you break it it just do like you would any other car-max everything up! (A/C, rpm, etc.). That's what I would do anyway, but I'm sure other people have ideas as well.

The CRD owners manual says:

ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle) in
your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws, contributes
to a good break-in. Wide-open throttle acceleration
in low gear can be detrimental and
should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving type
lubricant. Oil changes should be consistent
with anticipated climate conditions under
which vehicle operations will occur. For the
recommended viscosity and quality grades refer
to “Maintenance Procedures” in “Maintaining
Your Vehicle”. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its
first few thousand miles (kilometers) of operation.
This should be considered a normal part
of the break-in and not interpreted as an indication
of difficulty.
Additional Requirements For Diesel
Engine — If Equipped
During the first 1500 km avoid heavy loads, e.g.
driving at full throttle. Do not exceed 2/3 of the
maximum permissible engine speed for each
gear. Change gear in good time. Do not shift
down a gear manually in order to brake.


What speeds then for the first 100k's as it say only 80-90kms after that?

The main thing is not to thrash it when cold and to let it idle for atleast 10 sec after stopping. This will make the turbo last longer. Most wear and damage occurs when the motor is cold. I have always broken my cars in with normal driving, never babied.

What is the story with turbo timers these days, I had one on my 1985 Cordia are they still legal/recomended?

TT's have not been recommended by new car makers for years. The newer Turbo cars all have their own tech to maintain cooling and lubrication for the turbo after shutdown.
I would not bother with any aftermarket stuff like that. All I do is drive moderately for the last few mins of a trip then let the car idle for about 20+sec before I shut it down.

You tried telling your wife not to rev the engine while parking, and not to shut down straight away?
And count to 20sec? it is longer then most would think when all they want is to get that dress on special! Or running late for church.
Mine could not get the hang of it. And would complain about me idling she would get impatient and walk of.
So I fitted a timer. (this is on my old jeep).
But saying all that hot bearings are the biggest killer.
Driving around town it will not get that hot.
And leaving a freeway or hwy driving to your parking spot it will have cooled down.
Spinning is not an issue slow airflow brakes the turbo fairly quickly.

Lawrie, I said That " I " do these things, the wife does not care and her eyes glaze over when I tell her about turbos and lubrication and well you know what I mean.
Thankfully all she does is the school run and shopping, I bet the turbo hardly spins....

To those that have used Diesels in Australia for a while do you occasionally use a external fuel filter to check for contaminating. I purchased on of these focused on those times I'm away from the city areas but is it worthwhile in the city also?
