Diesel Oil Change

What is the correct procedure when changing oil in a diesel engine, ie
flushing/cleaning.

(yes, I have changed oil before in petrol engines but diesels seem to
require cleaning and flushing)

1. Drain old oil.
2. Replace drain plug (important!).
3. Refill with new oil.

Why are franchised dealers so insistent on flushing oil? Apart from the
obvious profit motive.

Except with l/r tdi engines when its item 4....

Because so many are run to the change limit, and beyond it, and don't do
enough fast miles to keep the sludge levels down, slow round
town/off-tarmac driving means more circulation/use between changes.
Take a look at some of the lube advice web pages to get a feel for it.
I run 3k between changes, not 6, and flush every third change to try to
keep the turbo from coking its bearings etc, though stopping a hot turbo
after a fast run isn't good for it anyway, keeping the engine running
for a few minutes allows the turbo to cool gradually and the oils to
keep flowing not boil off and clog the bearings with coke, flushing
helps unsympatheticly driven engines survive....

Is it a bad idea to remove the filter after draining (before refilling)?

I am always worried when doing this, I watch the oil pressure light very
nervously when starting after a filter/oil change. When you're watching
it like that it seems to take an age to go out!!

Yes, I do, putting in as much as the filter will hold. I was just wondering
if the Tdi's are like the V8 in that if you remove the filter with the sump
empty, then all the oilways drain down.

The 200 seems to, IIRC they use the same filter, which has the NRV so
from what I seen they do drain down.

Niel.

So it's....
1. Remove oil drain plug.
2. Drain old oil.
3. Remove old oil filter.
4. Fill new oil filter with as much oil as you can.
5. Fit new filter.
6. Replace drain plug (important!).
7. Refill with new oil.
8. Start engine, but do not rev until oil pressure warning light goes out.

easy peasy....

And recheck oil level.

It always looks more complex on paper than it actually is;-)
