From what I've read up on previously, Mobile 1 oils is mixed oil and not pure synthetic oil. Mobile One is mostly a group III oil which comes from the ground. Mobile 1 used to use Group IV oil however after they lost their lawsuit with Castrol over them advertising Group III as full synthethic, they downgraded the Group.

Redline Oil is probably one of the best out there, Group V oil with a great addivitive pack. IT has Phosphorus, Zinc, and Moly and the base oil ester is a great cleaner and dispersant by itself. Most Mobil One products have little to no moly and 600ppm or less ZDDP, half of what Redline uses.

This post might scare you guys running Mobile one! :eeps::eeps::eeps::eeps::

I have been crusing through this site and noticed there is a lot of misinformation and confusion about oil. Here are a few things you should know about oil for BMW's:

1) All new BMW's require synthetic. As far as weight, only certain production dates of M3's and M5's require the use of Castrol TWS 10w-60.

2) The Factory BMW Synth 5w-30 is a version of Castrol TXT Softect sold overseas. A few important things about the BMW oil a) it is a Group III hydrocracked oil which cannot be called synthetic in Europe, b) it is a heavy 30 weight (30 weight can run from 9.3-12.5cst@100c, the BMW oil is about 12.2cst), c) it is a ACEA A3 oil which means that it is approved for longer change intervals and has a HTHS (High Tempurature High Shear) measured at 150c of greater than 3.5.

3) In the US, the only Group IV PAO Synthetics that are available are 1) Mobil 1, 2) Amsoil (but not the Xl-7500), 3) Royal Purple, and 4) German Castrol 0w-30 (it has the red label and says on the back, "Made in Germany). Redline is a Group V PolyEster based oil. All other Castrol, Quaker State, Pennzoil, Valvoline "synthetics" are a Group III hydrocracked oil. It is debated how much better Group IV base oils are than group III, but generally they are considered better.

4) When looking for oil for any BMW that does not require Castrol TWS 10w-60, you want to purchase an oil that has either/both of the following ratings, a) ACEA A3, or b) BMW LL-98 or LL-01.

5) Note that Mobil 1 0w-30, 5w-30, and 10w-30 are NOT ACEA A3 or BMW LL approved oils. This is because they all are thin 30 weight oils (approximately 9.8-10 CST@ 100c) and have HTHS of approximately 3.1. Mobil 1 0w-40 and 15w-50 are A3 rated and the Ow-40 is BMW LL-01 approved. For 99% of climates and users 0w-40 or 5w-40 is the appropriate grade. There are some 0w-30 and 5w-30 oils (like the BMW 5w-30) that are forumlated on the heavier end of the 30 weight scale and are accordingly rated A3. These oils will work well also. LOOK FOR THAT ACEA A3 rating. If the oil doesn't have it, pass on it.

6) Some people seem confused about how oil thickness is measured. The first number (0W, 5w, 10w, 15w, etc) is a measurement of how thick the oil is at tempuratures of -35c- -20c (depends on the grade). The lower this first number the thinner the oil is at LOW tempuratures. The second number (30, 40, 50) refers to oil thickness at 100c (operating tempurature). 30 weight can be from 9.3-12.5 cst, 40 weight from 12.6-16.2 cst, 50 weight from 16.3-22cst (approximate). So you can have two oils, one called a 5w-30 (i.e. bmw oil) another 0w-40 (Mobil 1) that are very similar thicknesses at operating tempurature. Compare this to Mobil 1 Xw-30 which is close to a 20 weight oil at 100c. For more information here is a link with exact numbers http://www.bobistheoilguy.com/visc.html

7) BMW's recommended interval of 12,000-15,000 miles is to long. Used oil analysis has shown the BMW oil is generally depleted at 10,000 miles. Running it longer results in excess wear. It is highly recommended that you change your oil once between each BMW recommended interval (approx 7000-7500 miles). If you want to run your oil the BMW recommended interval, I would suggest that you use Mobil 1 0w-40 or Amsoil 5w-40 and change the oil filter at 7500 miles. I would encourage a full oil change at 7500 if you want your engine to last.

I also checked Mobile 1's website to confirm #5 and it is still true, not BMW approved as it's to thin (11.3 at 100C) and it's shear is 3.1 @ 150C

All I can find is that ACEA A1 approved, not A3 so I'm going to say no.

AFAIK Mobil-1 was the official recommended oil in BMWs before 99. however I'm not 100% sure. I use Castrol personally

you might need to, it all comes down to where you live and how thick/thin the oil needs to be to provide proper lubrication.

An oil like Mobil 1 5W-30 isn't rated properly for bmw motors as it's HTHS is only 3.1.

Mobil 1 0W-40 is ACEA A3 approved along with BMW Long life because it has the HTHS of 3.7 so it should be good!

ACEA A3 means that the oil has a better High Temperature High Shear (HTHS) rating. A1 and A5 are up to about 3.4, A3 is 3.5 or better. BMW and most other german car makers demand 3.5 as the minimum so the oil can stay true to it's properties for longer and provide better wear protection under harsh conditions even near the end of the oil change interval.

EDIT Mobil 1 ESP Forumula 5w-30 meets ACEA A3 requirements! As far as longetivity and so on, no clue.

the reason why bmw want you to get the 3.5 is because bmw does oil change at about 15000 in which regualr mobile on with 30w will not work. 40w is thicker and will hold up . the reason why bmw does this is because they give free maintnance and if they had to chnage oil at 5k it will cost them 3 times as much. if this was an m series or v10 like m5 or high performance i would see the need. but if you change your oil on a normal basis 5k you should be fine with mobile 1. thats just my own 2

I generally use 0W-40...Mobil-1 or Castrol, though am not opposed to the normal BMW oil, as it's just rebranded.

The 3.5 is a test of how much the oil will change over the course of it's interval. The purpose is partially for longer fluid changes, but more-so to help protect the engine from high wear and tear when it is being pushed. If the oil is below say 3.5 and you have had it in for 5K miles there is some reduced abilities of lubrication to the oil. At that point, take for example my 760. I can drive it nicely around town and have adequate protection from Mobile 1 5W-30 that's not approved by BMW. However if I ever get the urge to mash the pedal and hear the 12 cylinder heart of the 760 growl, I'd probably end up doing quite a bit of damage as the oil won't be able to hold up to the sudden increase in temperature, pressure and load. Maybe if it was newer it could handle the load a few times, but once the oil starts wearing, it only goes down from there.

You have to remember that M's are built to higher performance figures (such as the V10 in the M5/M6 reving up to 8K RPM). When you are pushing a motor that's drawing every single ounce of power out, regular oil won't cut it, and that's precisely why they use a different oil weight and composition than we do.

I use AMSOIL for European full synthetic 5W 40. You can instantly hear the difference after changing the oil. I put AMSOIL in everything I own.

I see you didn't quite finish your thought, would you care to finish it for us?


Just so you guys know, I don't have anything against mobil 1 oil, I use it in my other car with 90K on it since it's approved for it and have been using Mobil 1 since the day I got rid of the factory fill oil. I'm just posting the info straight from Mobil's Product Data sheet so someone doesn't come on here and say, oh, 90% of the people on the E66 section use Mobil 1 so I will to, and then their car starts consuming a quart of oil every 600 miles and then goes though the trouble of figuring it all out. I'm not going to take the chance if I know it's not approved for the 7 and hopefully others make an informed decision with the info that's posted.

I have never use mobile 1, I live in australia so dont know what the oil difference is around the world but

The castrol edge sport 0-30 we buy off the self is different from BMW 0-30 BMW stuff. Been told we the german BMW oil 0-30 acts like 0-40, therefore getting the castro 0-40 off the shelf is a better option.

The reason why is that the base oil for castrol is allowed to be a lower base value .. while in europe they are strict on this.
