You actually read something into my post that I didn't say.-

In your post you said yourself it was UN-Necessary which then begs the question------Why do it then ?????------Very odd.--
I do it because like I said I still like to see the oil not completely black, its simply my way of doing it, I agree its not necessary until manufacturers recommendations but old habits die hard with me. It has kept me in good stay in the past during my working life. When I check my oil it is nice to see it clean on the dipstick especially on a diesel.
I hope that clears my take on it.

I do not wish to take this thread away from Artics excellent how to.

2, I just realized that I don't take off my engine cover to change my oil filter (silly me for not realizing earlier!!) I'm sure there is enough room to do it with the cover in situ. Doesn't detract from your excellent "how to" though. As mentioned this may encourage others to have a go, which in my opinion is worth it's weight in gold!! Thanks.

Hi Lee.
The bolts on the under tray/ engine shield are ones I added myself as I was fed up with the 1/4 turn ones going missing and not completely secure, so I used spires and 10mm self tapping bolts, I always take the engine cover off it just gives you a little bit more room and again you can make a visual inspection injectors and fuel line hoses etc, also I changed the air filter and PCV and fuel filter at the same time so again it would have to be removed, the under bonnet pump was used through out the range as mine was a 2004 model, therefore in theory should not have it, these R75 car are always throwing up surprises.

When I drain oil from a diesel I still want to see a glimmer of gold colour and not just jet black, this works for me.
If it has worked for you then its great, just not for me.

Still a perfect how to for anyone.
Lots of larger engines have two oil filters, a normal one, then an extra fine one through which a small proportion of the circulating oil passes through.

I agree with Colvert - Filters do actually become more efficient as use progresses, but its a trade off between efficiency and flow - leave it in long enough and there will be no through flow because it will choke. Not sure whether the M45 has one, but some filter housings have a by-pass system, to by-pass a filter if it becomes completely choked.

So changing your filter too often, might not be a good idea.

Mine does around 6K per year, so I change the oil annually, the filter every second year.

The oil in a diesel BTW, is supposed to be black. That is the oil doing its job properly, in washing all the dirty combustion products out and suspending them in the oil. The oil in a diesel will turn black within just a very few miles.

Arctic, yes I knew about the extra pump on the earlier models, I was just trying to understand the reason for the bolts on the undertray so was using this as a reason, thought for a minute I was missing something!!. That's a good idea to replace them, fortunately I bought new screws and everything's fine (so far) in that department. I know what you mean about these cars throwing up surprises, mine is a 2004 and has a single in tank pump, as does my wife's 2004, yet my sons has 2, also a 2004, go figure!!!!. Thanks.

Many thanks Arctic for your excellent post on the how to "change your oil" These posts are absolutely invaluable to the likes of me, so even stating the obvious is a god send for plonkers like me .
Not all of us are mechanically minded but that does not mean we dont like getting our hands dirty. In-depth guides like this just give the less confident the opportunity to tackle jobs they would normally shy away from and saving a few pounds in the process
Keep up the good work Arctic ( its always appreciated )
Johnny

I Arctic,
Always good to see photos rather than reams of text, personally I use a Sealey TP69 vacuum pump. It has a 6.5 litre tank, good enough for our engines.

As for extra hands for the funnel, I cut the end off, so much easier. see photo.

Default Link to eBay filter?

Hi Arctic, just a quick verification, the eBay link at the start of this thread to an Oil Filter, the eBay site states that it will not fit SE Connoisseur CDTI ? I have a sneaky suspicion that your superior knowledge may nullify what is stated: will it fit my 2.0 CDTI?
