Whatever oil you use you better be sure it meets BMW's requirements for approval standards and viscosity range. People who use Motul say it's the best ever, and so on. This is a question of endless discussion and vituperation, flame wars, and personal slagging on the bobistheoilguy forum I referenced above. I can't tell you which oil is better, Castrol or Motul. You can learn more about used oil analysis on this web site -, and particularly their oil forum. is Blackstone Don't know what region of the world you're in, but there may be some labs locally to you. Suffice to say that most labs will flag any item measured if it is beyond their accepted limits, particularly if they think the oil is no longer serviceable in your servvice. Interpretation of UOA reports is a subject too broad to go into here. When you change the oil, you take a sample in a small bottle provided by the lab, send it off by mail to the lab, they analyze it for certain wear metals and, most importantly, the CONDITION of the oil, and a short time later they send you a report of the afore mentioned. The N20, as best I can determine, takes 5 liters for an oil AND filter change. I don't know if that will burn the oil much faster or do I need different viscosity, I want to know whether the Motul X-cess 8100 5w40 is same or better than Castrol Edge 5w40 and what is the liters recommended for my engine which is N20 ? Thanks in advance I have three choices of oil only, Shell which the dealer uses but it only lasts 10 thousands kilometers and in hot weather like we have I have to change it at around 5k kilometers, Castrol which is made specific for hot countries like here which lasts about 15k kilometers but I change it at around 8, so this Motul is new here I wanna try it but I want to know if it's any better, same or worse than Castrol that I use btw my car is tuned with JB4, dp, exhaust ect. Any particular reason you want to change brands?įirst thank you a lot for your reply, I am sorry but I am trying to understand the shortcuts you use as I'm new into oil stuff, I just understand the numbers like 0w30 ect. All good news for high heat turbo engines.Īre you doing UOA's on your Castrol.
I think one reason BMW may have switched from Castrol to Shell is because Shell appears to be way ahead of the others in the refining and use of GTL (gas-to-liquid) base stocks which produce a motor oil that is very clean/deposit free, with low volatility and a high resistance to oxidation. Starting in 2015, new BMW's will switch to Shell/Pennzoil and an oil like the PU Euro will probably come in the crankcase. It's the service fill for current Ferrari's.
There is a 5w40 oil with PAO base stock, according to its MSDS, that is BMW LL01 approved and it may be more readily available than Motul: Pennzoil Ultra Euro 5w40. Some people think the 8100 x-cess line is Grp IV PAO base stock, tho I've never seen any MSDS that might show that.
