Interesting Facts From Mercedes Manual on CRD Engine

[TonyVideo]

I thought these facts were interesting from an online manual from a Mercedes GL320 which has the same engine as the Jeep 3.0CRD

Maximum oil consumption is .8 liters (.85 quarts) for every 1,000k (621.37 miles) The oil consumption may be higher than this when the vehicle is new or if you frequently drive at high engine speeds. You can only estimate the oil consumption after you have driven a considerable distance.

2 Liters from minimum to maximum levels on dipstick.

Warm up the engine quickly.
Do not use full performance until normal operating temperature has been reached. (common sense).

The first 1,500 km (932 miles)

If you treat the engine with sufficient care from the very start, you will be rewarded with excellent performance for the remainder of the engine's life.

*

You should therefore drive at varying road and engine speeds for the first 1,500 km.
*

Avoid heavy loads, e.g. driving at full throttle, during this time. 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.

*

Try to avoid depressing the accelerator pedal beyond the pressure point (kickdown).
*

Only use ranges 3, 2 or 1 for slow driving, e.g. in mountainous terrain.

After 1,500 km you may gradually bring the vehicle up to full road and engine speeds.

When refuelling vehicles with a diesel particle filter in countries outside the EU, only low-sulphur Euro diesel with less than 0.005 percent sulphur content by weight should be used. In countries in which diesel with a higher sulphur content is available (e.g. 0.035 percent by weight), the engine oil should be renewed at more frequent intervals. More information about intervals for changing the engine oil can be obtained from any Mercedes-Benz Service Centre. NOTE: I don't know how 15ppm here in the US stacks up to this. It is my understanding after "Googling" that Europe is 10ppm.

Do not use the following:

*

marine diesel
*

heating oil
*

bio-diesel
*

vegetable oil
*

petrol
*

paraffin
*

kerosene

Do not add such fuels to diesel fuel and do not use any special additives (exception: flow improvers - see "Low outside temperatures").

Flow improver

The effectiveness of a flow improver is not guaranteed with every fuel. Observe the information provided by the manufacturer when using a flow improver. Only use flow improvers that have been tested and approved by Mercedes-Benz. Information about flow improvers that have been tested and approved by Mercedes-Benz can be obtained from any Mercedes-Benz Service Centre. NOTE: I did some checking and came up with this.

This is all I could come up with from the Mercedes manual. I didn't cover oil specs as that has been beaten to death. 229.51 :-)
