All the Factory Fill Oil is now a Castrol Synthetic, but it is not the same as Castrol Syntec.

You can't buy the same oil that comes in the car correct?


And when the dealer does an oil change do they use Castrol Synthetic?

OEM is Castrol. AndyM's manual specifically says Mobil1 is OK so we are using it in his car. Curious if yours says same thing.

Yes you can. Just go to your dealer and buy BMW Synthetic motor oil. That is what they use.

BMW oil used to be made by Valvoline, now it is made by Castrol.

As far as I know, the BMW Oil available from the dealer is the same oil that comes from the factory. This oil is made by Castrol for BMW and is only available from BMW, at least in the USA. In other words, it is not the same as Castrol Syntec that you find at local retailers.

The big deal, if I understand it correctly, was many people thought the BMW Oil _was_ Syntec and did not like using it because they felt it was not a true Synthetic.

We have a 2001 Z3 Roadster and it says the following:

SPECIFIED ENGINE OIL:

The quality of the engine oil which is selected has critical significance for the operation and service life of an engine. Based on extensive testing, BMW has approved only certain engine oils.

Use only approved "BMW High Performance Synthetic Oil."

If you are unable to obtain "BMW Hight Performance Synthetic Oil," you can add small amounts of synthetic oil in between oil changes. Only use oils with the API SH specification or higher.

My old 2002 E46 and my current 2003 E46 Manual's all say something very similar.

After much debate and research, I have decided to use only BMW Oil in my car. If I were going to use an alternate oil it would be Mobile One, Redline or Amsoil.

I would think that Syntec would be fine, but given all the talk about it not being a true synthetic and not meeting the BMW Long Life Spec, I would probably not use it.

The main point is, if you change your oil at shorter intervals you will probably be fine.

BMW Oil

There is a "BMW Long Life Oil" specification. Valvoline Synguard (?)also fulfills them. BTW my dealer used Castrol for my oil change and not OEM.

I think that it was in this very forum that I read that the service instructions "recommend" BMW Oil, but for M they say "use only" Castrol.

For the S54 engines (E46 M3, 01/02 MZ3s, also M5 and Z8), ONLY Castrol TWS or RS 10W-60 is required. All other BMWs use the standarad BMW 5W-30 synthetic.

Castrol Syntec is fine.

There are two ways to produce a synthetic oil. Built up what you want from little pieces or specified crack large pieces down to the size you want.

Both produce an oil base stock not found in nature and both are synthesized. Mobil 1 uses the first method, Castrol the second.

According a petroleum engineer friend of mine (and backed up with tech papers on Chevron site) you can actually make a BETTER oils from second method.

My 2003 330i has imprinted on the oil filler cap "BMW Recommends Castrol". I'm therefore assuming that Castrol Syntec is OK.

This entire Oil thing is an ongoing debate and you can do a search here and read plenty.

As Pinecone said, there are two ways to get a Synthetic Oil and both achieve basically the same result.

If you look in the manual it specifically says the only approved Oil is BMW High Performance Synthetic, which happens to be made by Castrol. Again, this is not the same oil as Syntec. As I understand it, the BMW Oil is actually formulated the same way as Mobile 1, whereas Syntec is formulated using the other method. Now, I may be completely wrong on this, so do not hold me to it.

As for your Oil Filler Cap, it is my belief that has more to do with Marketing and the relationship between BMW/Castrol.

The two things that concern me are:

1. Change the oil more frequently than the BMW recommended intervals.

2. In the concern that my car does experience Engine Problems, I do not want to give them an excuse to deny warranty coverage, should they do an Oil Analysis.

That said, based on the research I have done, the BMW Oil appears to be very good oil. In fact, someone posted an analysis of the 5W30 used for 15,000 Miles in an E39 and the oil was still good. Obviously, every engine is different and if you intend to follow the recommended interval, I would suggest you have the oil analyzed. Unless, of course, the car is leased and you have no intention of keeping it.

Castrol sells completely different motor oils in Europe than here in US. BMW oil weight specs are also different for US sold cars.

Castrol in Europe sells few products that will meet both ACEA A3/B3 and BMW Long Life.
These are the choices:

Castrol SLX LL 01 FE 0W-30 Ė BMW OEM fill and recommended oil

Castrol SLX 0W-30, meets ACEA A3/B3/B4 and BMW LL-01

Castrol RS 0W-40 Race, meets ACEA A3/B3/B4 and BMW LL-98

Iím not sure if Castrol TWS Motorsport 10W-60 meets BMW LL-01 but it meets ACEA A3/B3 and is the only oil recommended for all European M5 engines build before March 2000 and all S54 engines. They also sell Castrol RS 10W-60 that meets ACEA A3/B3 but not BMW LL and there is no recommendation for BMW engines.

Castrol sells a few more synthetic oils and some are brand specific like Castrol SLX LongLife II for VW/Audi, etc and they claim that these oils are designed to meet specific needs of certain engine type and are not a marketing plot.

The only Castrol oil sold in US that meets ACEA A3/B3 and BMW LL-01 is Castrol Syntec 0W-30. This oil was imported from Germany not so long ago and you may still find a bottle that says Made in Germany. Iíve heard that it is Group IV basestock and is probably European SLX 0W-30.
Syntec 10W-40 and 5W-50 both meet ACEA A3/B3 but not BMW LL-01

Based on information that I could gather I know that BMW Synthetic is not a Syntec even though it may be blended here in US. This is the oil Iím sticking with and at $3.80 at your local dealer itís a great buy.

The new red label 0W-30 is the European Castrol SLX rebottled, look on the back for the RED label 'made in Germany', not the old YELLOW label 'made in the US' formulation.

This stuff should retail for $6 qt, but Castrol is selling it as a loss leader to keep in line with regular Syntec pricing, and hopefully doesn't expect that high a demand for it. They brought it out to satisfy the European ACEA A3/B3 requirements.

Are you sure it's still available? If it is this would be the oil to use for folks up North.
Just to check I'm going to see I can find it at my local AutoZone.

I've only seen it at Autozone so far, Wal-mart, etc. only carry the Syntec 5W-30. I've read others have found the yellow labels still floating around.

Somehow I doubt the 10w-60s will ever meet LL-01. I believe one of its key requirements is flowability in order to service certain Valvetronic components (the primary reason why LongLife was updated from LL-98 (or just LongLife before -01 existed)). So far I've only seen 0w (the mentioned Castrol and Mobil1 0w-40 US and ECE) and 5w (Motul LL-01).

I actually have an official BMW list of approved oils (for HighPerformance and LL-98, I think) at home. I should post that when I get a chance.
