Oil Change Diesel R75 MGZT

[Busboy]

I am about to attempt my first oil change since acquiring my car last Sept I have covered 6k Miles and the oil is as black as the Ace of spades! (I do mostly motorway mileage and rarely exceed 2k RPM ( And cruise happily at 70 MPH! my car has FSH from new and as far as I can see all has been done properly inThe past.

I have collected all that I need : Oil :Mobil 10/40, Slick 50 (used it in 17 cars over 30 years!), Oil Filter, 36 mm low profile socket, fuel filter, air filter, a sealy vac extractor , this is because like so many other members I would prefer to do it this way as I do not want to have to invest in a new trolley jack or heavy duty axle stands and have to grovel around trying to remove the engine tray. I have watched the you tube video of the american Topsider in use and I recommend every member that does not have access to a proper lift or pit to view this as This method just looks the buisiness , if the topsider was available in this country I would have surely bought one but imported from the US it would cost nearly £100.

When it's all done I'll report back!! :

As always an excellent how to, however I prefer a Pela-type of system works a treat, no mess no undertrays, every drop extracted, do it twice a year, with good quality oil/filter.

Hi Joe & Keith.
Nice bits of kit but it will not do a visual check of other parts under the car for you ie, hoses, lower engine mounts, lower wish bone bushes, turbo hose and leaking from the compressor and such so the old way is for me, Good luck with the service.

Excellent how-to as always

Worth highlighting that when fitting the new large O ring onto the oil filter housing, it doesn't go in the top groove as you might think, but in the second groove down (as seen in fig 32).

I cut a hole in my undertray to allow access to the sump plug. Fortunately there were a few drips to mark where to cut! First time I changed the oil it took me longer to get the undertray back on than the rest of the job combined. Now changing the oil is so quick it almost doesn't feel like a 'proper' job anymore!

As Arctic says, still important to get the undertray off regularly to have a proper look around. Just nice not to have to when changing the oil if I know all's well elsewhere.

Surely if that were the case we would never need to change an oil filter - ever, there is a reason Royal Mail always fit an extra oil filter to their diesel trucks, it keeps the oil clean and prevents long term problems, it was a practice I adopted when running my wagons also, I would not take a chance on letting a filter get clogged, twice as often is always better than twice as long.
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.

Agreed Steve. The bolts on mine are all all the same size. But as there have been few reported cases of people puncturing through to the camshaft chamber due to having different length bolts and refitting a longer one in the top left hand position.... best to check.

Great post Steve, and timely too. With Easter approaching, maybe a few deals going on with the price of oil. Post will encourage the not so confident to tackle this very worthwhile task.

Arctic, a quick question, I just re-read your how to and realized two things.
1, you have bolts holding your undertray on where as mine has those awkward large threaded screws, is that because yours is an earlier car(noticed the extra under bonnet pump on the picture) or because yours is a manual?. I didn't even know the undertrays were different on manuals and autos!!.
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.

Slight miss reading of my post. I didn't say Don't Change it. I merely said that throughout the course of its NORMAL life it slowly becomes more efficient.
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.--
