Hello,

I am just about to change engine oil in my 2006 320d E90 manual.
I have a few questions regarding this :

1. Is Castrol Edge 5W40 all right ?
2. How much oil do I need ?
3. How to change oil filter ?

I would be really greatful if you could help me
I think I can find the bolt underneath the car to take the old oil out.

Thank you,

Mat

There is a guide on the forum for changing your oil and the filter, find that and study it if your not confident going at it blind.

You should really use a low saps bmw specific grade 5W30 oil. Ignore the brand and focus on the rating and the grade. Have a look on opie oils as they have a good range for about £40 a gallon. You will need 5.5L.

It is for petrol and diesel engines.

I just found this here on this forum :http://www.e90post.com/forums/showthread.php?t=4768
Thats for 325i E90, so its a lot easier. I think I need to take engin cover off to change oil filter on 320d. Its even harder to change air filter. Ohhh that nasty 320d engine configuration

[Tipper]

No need to take the engine cover off for oil filter change but you will need a very large socket wrench...36mm iirc. The filter is nothing like that in that thread.

I haven't done the air filter yet but it looks ridiculously complicated to me!

Cheap and cheerful but fully compliant. This is what I am using atm.

Ohhh, thats good not to take engine cover while changing the oil filter. 36mm wrench, thats a big one.
I am wondering if I should buy K&N air filter or not. It takes 2.5 hours to complete the job I found. Here it is :

Thats a very nice price. Castrol Edge is almost 2 times more expensive and I am wondering if it is worth the price hmmm....
For the 320d I need to use LongLife-04 right ?
0W-30 oil is LongLife-01, so I suppose it wouldnt be suitable for 320d.

Only use LL04 oils in am E90 car.

Ok, thanks

I have a big job to be done, excatly :
- engine oil + filter change
- air filter
- microfilter
- new tyres on my old 16" wheels

Air filter change scares me haha... It is so hard

[JonnySi]

The air fiter is a doddle, i could do them in 20 minutes, we used to have a competition at work as to who could do them the quickest.

[LexS]

A light service like that will take you an hour, nothing to worry about.

Here is a spec list of the oil I listed previously. It has all the necessary requirements for our engines.

Ohhh, 20 min. is really quick if thats true. If you have done a lot of them its easy then, but in my case it is 1st time so its gonna take a lot of time lol.

I hope its gonna go swiftly with no bigger problems. The air filter will be a big challenge lol. I also need to buy some 36mm spanner as you mensioned for the oil filter replacement.

Yeah, I think I will get the oil you mensioned. It meets the sepc and is a great price. I am just wondering if it will last for a year as I do servicing every year.

What do you think about this one :

Even cheaper than the Carlube one lol.

[LexS]

Should be fine. Looks the same as AC Delco oil which comes from Vauxhall, all under the GM umbrella.

Perhaps you could give us the run down on your quick method?

[JonnySi]

Well, it helped the fact I was replacing them on a daily basis, but with a large selection of tools and the right technique they are fine to do. I would say for a job at home they are chewy because getting the airbox to sit back together properly is a total mission. It may seem correct but it probably wont be.

Was told by the dealer that the oil was 0w 30 for my 320d not 5w 30 but the Castrol web site says 5w 30 so not sure which one is right.

Oil recommended for 320d is LL-04 (LongLife-04).
Both 0W30 and 5W30 are LL4, so really id does not matter to be honest with you, but as the member of the forum says the better option is 5W30, because of a density or grade. I do not know what these numbers represent to be honest with you.

The oil which has a 'Turbo Diesel' label on it and also LL-04 specification is 5W40, its here :

[LexS]

The very simple way to view oil ratings, albeit it not the whole truth is that the first number is representative of minimum operating temperature. So 0W which stands for 0 Winter will effectively lubricate from a lower temperature than a 5W or 10W and so on.

The second number as has been explained to me is of heat resistance before degradation. So a 30 is quite thin and good for high efficiency engines, a 60 will be thicker and provide more resistance, but will take a healthy amount of abuse.

In my weekend car I run 5W40 in the winter, and 10W50 in the summer when I can rely on warm weather and do a few trackdays.

Thanks very much for the explanation.
What do you thik about this one :
http://cgi.ebay.co.uk/Castrol-Power-...item2563f02397

It is 10W30 and its not LL-04 spec, so I doubt such buy.

I will get 5W30 oil, which is good for all year long, kind of :P
