Anecdotal yes but something must be said of engines that are now 11 years old, pushing 5400lbs, closing in on 200,000 miles, and still cranking out 600+ hp with sub 3.6 0-60 times and mid 11's in the 1/4.
I run Certec once every 30-40k miles and 2 cans of Mos2 with every 5000 mile oil change (do not run them both at the same time). I run LM 5-40 oil also but any quality 5-40 will do.
I can only give you information from my experience and the few others I know that run Mos2 on this platform. The N63/S63 & TU variant engines are identical when it comes to what we are discussing here - Oil pumps, bearings, rods. BMW does not recommend any additives however it is important to keep in mind BMW is not your friend when it comes to oil & its recommendations. All oil recommendations serve CARB regulations & profit first, reliability & drive train life is a distant second.
A quick call to your dealer to schedule a transmission oil change will confirm how much BMW has your interests in mind. You will be told it is "Lifetime" and never needs to be changed, directly going against what ZF, the maker of your transmission, recommends. I think of BMW as a company with brilliant engineers headed by a diabolical management/marketing team. (Monthly fees for heated seats anyone?)
What I recommend is to look at the data and read up on MoS2, there is some solid science behind it: https://en.wikipedia.org/wiki/Molybdenum_disulfide
I would also change to a 5-40 weight oil and look into getting higher octane, here is a link to a map of E85 in Oz: https://www.glpautogas.info/en/ethan...australia.html Mix in 4 gallons with each fill-up. If you monitor your air/fuel ratios, you can play around with finding the perfect mix for your tune but 4 gallons per tank is a great starting point . It boosts performance (you will notice a bump in HP due to the timing increase) while at the same time adding protection against pre-ignition. It is worth the hassle to mix in. |
Thanks for the detailed reply, i think i will give Ceratec ago for my next oil change. Like you just wary of engine wear, and possible failure as with the unfortunate OP. Already have switched to LM 5w-40 since taking ownership of the car but it has only been 4000kms and one oil change when i first got it.
