The problem related to contamination during assembly in the lubrication system and oil pump tolerances for vehicles built Oct 2001 > Feb 2002. Not quite sure what Castrol had to do with it, given the vehicles were using Mobil 1 at the time of the incident. Surely Mobil/Exxon would have been involved in the investigation, if BMW engineers felt their expertise was required...? As mentioned in another post, it's marketing and BMW doing a deal with a supplier. Which BMW owners mostly put in Castrol because "it's recommended", regardless of the specification required and other oils meeting that spec? If they "recommended" another manufacturer, most BMW owners would use that instead. Last edited by G82Dude; 12-06-2012 at 05:06 PM.. |

I had my 335i serviced about 2 months ago at a main dealer. I asked the mechanic what oil they used as I wanted to provide my own oil and was told that they only used Mobil 1 0W-30 ESP for the N54 now as that was the new recommendation from BMW HQ.
Unfortunately that oil seems very hard to come by in this country as most of the usual suspects don't seem to stock it. Eventually managed to get 8 litres of the stuff off an ebay store for a great price. |

You'll be OK with Mobil 0W-40 New Life as an alternative to ESP.
