One thing to bear in mind is your entries will be overwritten if you take it to BMW for a service, so you'll have to add them back in again afterwards, starting with the oldest first.

I don't bother with any of that stuff. BMW get it once every 2 years and I do several interim oil changes myself, but don't record them.

Same here, although the next BMW service will probably be the last as it will be @100k miles.
From then on its unlikely BMW will assist with goodwill if anything should go wrong.
And as for service records for the next owner, its probably unlikely there will be one of them either.

But where did you read that? On the internet and written by a 12 year old? Ask BMW or an oil company, that is not a mechanic at BMW nor someone who works in a shop selling oil.
You are just spreading fake news without a credible reference.

You got me, yes the internet. As to verifying the age of anybody who posts, sorry no way I can check that. Whilst I’m not an engineer the logic of a thicker oil in an older/higher mileage engine makes sense to me. Internal wear over time leading to possibility of leaks being mitigated by a thicker/heavier oil. One of the earlier posters refers to misting from using 0w30. Both the grades I’ve mentioned in my posts are approved by BMW. Bit of a stretch to say spreading fake news, I’m asking a question based on what I understand in the hope that somebody who knows can either verify or refute. Thought that was one of the helpful features to a forum but seems easier to come on the bounce.

It's well known with BMWs (Honda's too) that upping the viscosity a touch can make the engine that bit smoother, that bit quieter and stop oil usage

All my E39s were 5W30 from factory; but at the age and mileage they were at; they got 5W40. As did both my E65 and F01 7 series and my currently F31 will probably get moved to 5W40 before I decide to sell it on (which more than likely won't be for another year or so)...

As others have said; 5W40 is fine, as is 5W30 - keeping it fresh is what's more paramount...

I personally wouldn't touch 0W30; it's like water!

Go for it then, your car. If thicker oil is better then why not fill the engine with grease? That would be great.

Seeing as you're all brains about this and know it all; prey tell, explain the whys and wherefores please, instead of being a smarmy prick about it...

Which seems to be the MO of your posts

Maybe he’s the 12 year old keyboard warrior.

Independent BMW specialists, who know more about BMWs than a regular dealer tech ever will, have recommended 5W30 for my 30d especially as the mileage increases (>100K now).

I’m happy to go with that, as well as replacing the oil and filter every year or 7K miles (whichever comes sooner - the car only does c5K miles per year these days).

[Danj94]

Just my 2 pence

my car is a B58 440i and the following info comes from the manual which I assume is the same for all of our f series cars.

Engine oil grades for a petrol should be any of the following;

BMW Longlife-04
BMW longlife-12 FE
BMW Longlife-17 FE+

for diesel engines..

BMW Longlife-04
BMW Longlife-12FE

As for viscosity classes for petrol

SAE 0W-20
SAE 5W-20
SAE 0W-30
SAE 5W-30
SAE 0W-40
SAE 5W-40

it does say explicitly that 0W-20 & 5W-20 are NOT SUITABLE for diesel engines and that higher viscosity grades may increase fuel consumption.

In my case the B58 was engineered to run on 0W-20 and I've had no issues. I can understand peoples issues with it though as it is thin but BMW know best right? or do they...

Anyway truth is any of those can be used and your warranty would still be valid so just use whatever you like in those limits and get on with it

oh and by the way I have referenced that information from page 283 of the owner handbook.

Yup; for the UK 5W30 is spot on; just older cars or very high miles, 5W40 tends to be more favoured to stop any OTT oil usage and a bit more protection for the engine. IIRC it takes a bit longer to get to its best in cold weather; but that's far n few between for us here really...

Like you I do very low miles; I'll do x2 oil & filter changes a year to keep it fresh. Costs the same as a full tank of premium fuel & it's peace of mind etc

He only responds to oil related threads. Probably because he rubs himself off with BMW Twin Power Turbo 0W30 every day. Anything less than that just doesn't get him going.

There's no way of telling if an older engine 'needs' a thicker oil unless it's stripped down and had all it's bearing clearances checked etc. But as BMW enthusiasts we are well aware of their engines enjoying a diet of bearings, so a thicker more stable oil is a wise move, especially as BMW themselves recommended the Police 530Ds switched to more regular changes of 5W40.

The only reason they recommend a 0W30 is to reduce pumping losses, therefore improve mpg a slight amount, which makes them look good in front of the Brussels emissions governing body. Everything car makers mandate is to benefit them, not us.

You are showing your expertise here, a 5W20, 5W30, and a 5W40 all take the same time to circulate the engine as the 5 is the cold viscosity rating.

Just for your interest, during my life long career in aviation we used to do laboratory oil analysis on used piston engine oils for aircraft and road vehicles. I do know that BMW know much more than you ever will.

Takes a lot to offend me pal; you just come across as a complete twonk in all your posts

0W30 is better suited to much colder climates IIRC

Tommo3, do try to keep up.

danb1979's point is that there's usually no need for 0W in the UK as the winter temperatures do not typically stay below the temperature range for 5W. He's right, AFAIK, that a 5W grade will take slightly longer in the same conditions, and in the same engine, to get to normal operating viscosity.

5W has a slightly thicker viscosity which can help to reduce noise in a bigger mileage engine.

Trying to make a point by referencing 5W20, 5W30, and 5W40 doesn't make any sense when the thrust of the point is that there's no significant reason not to switch from 0W to 5W. 5W is 5W in the cold temperature range, irrespective of the 20, 30, and 40 viscosity grades in the high temperature range.

Resetting Oil change on iDrive is surprisingly easy to do, see this video

Evening guys,

Only just getting round to this believe it or not.

Was in Costco today and grabbed a 10L of Castrol Edge 5w 30 for £52

I’ve got the Hengst pollen filter I previously linked too.

Would anyone know what oil filter I may need?

Also looked at the above and the oil reset really is simple so I think I’m going to give this a go myself along with the oil change.

Any tips would be appreciated. Never done an oil change 😄

Mann, Hengst, Mahle or BMW filter. Part number: 11428583898

Mahle here on Amazon:

MAHLE OX 1146D Oil Filter - Oil Filter with Gasket / Gasket Set https://amzn.eu/d/2bWHrlL

BMW filter here via Williams: https://williamsperformance.co.uk/pr...et-11428583898

[TurboWeasel]

I use the Mahle one as it's the same brand as the dealer supplied filter. Although I got 10 of them from AutoDoc at £9 each.

[J3OEF]

Thanks chaps!!

All ordered.

Just need to get the confidence to do it now and not put it off or try and get someone else to do it!

[dave550i]

Been reading this thread and for anybody with a dirty diesel like mine (640D) theres always this offer on Ebay from Newcastle mercedes https://www.ebay.co.uk/itm/131529847297 7Lts perfect for Bmw 3ltr diesels needing 6.5Lts now i know it does not state long life but i change my oil twice a year anyway and only do about 5-10K a year, LL oil is in my mind a sales pitch for company fleet owners, and who would really want to buy a ex fleet car thats been serviced every 20K+ miles? sure i woudnt, its 229.52 spec which is good for mercs high powered Diesels fitted with DPFs so grab a bargain comes within two days by courier £44 for seven litres is best out there surely, no connection with the company been using this for years with no problems at all.

I felt the same as you but it really is a doddle and very satisfying once done!
