I have been reading a lot about oil, especially since it came to my attention that some S65 engines seem to get rod bearing issues at some point in their lifetime... Since I don't have any issues at this moment, and I want to try and avoid getting them as much as I can in the future, I want to start this discussion and hope to share some ideas and experiences.
With regards to the oil most people use, they go for the oil that has been recommended by BMW: TWS 10w60. However, from my understanding of oil, this oil is quite a bit thicker than for example Mobil1 0w40. The thickness makes it more difficult for the oil to get between the rod bearings, connecting rods and the connecting rod bearing caps which could result in the issues people have been having.
Upon reading this topic: Whos running Mobil1 0w-40? I'm thinking it may not actually be a bad idea to go for Mobil1 0w40. It seems there are various advantages: engine warms quicker, lubrication is better (because the oil is thinner and can reach more difficult to get to areas - which is exactly what we need for our rod bearings) and throttle response is better since the oil is thinner/lighter (less resistance). The only real problem I have is that we live in a hot desert climate and Mobil1 0w40 may offer less protection at higher temperatures... Or would it?
So, my question is: has anyone tried driving on Mobil1 0w40 in our UAE climate? What are your thoughts about this? Would you recommend it? Or do you have some strong arguments against?
Also, has anyone ever done an oil analysis - an analysis which determines which metals are present in the oil that comes out of your engine --> this could determine which parts are wearing and can 'predict' potential issues that may occur in the future..??
Thanks!
