Anyways,I am new here and wanted to say Hi !

I got couple of questions :

1. i have 58t miles on my e92 M3 and i dont think that previous owner changed those bearings,should i do the change asap ? if yes,Should i go for BMW stuff or order custom like VAC ones ?

2. There is castrol engine oil in it and i read that its terrible oil,i was reading about this one even on these platforms and ppl said its good to go :

2007 M3?

[kscarrol]

Yes, a 2007 M3. OP is in Slovakia. In European countries cars are designated by the year purchased so an M3 purchased in in late 2007 is a MY '07 there. Here in the US we have a system of model years beginning long before the calendar year. An M3 purchased here would have been called a MY 2008... Hell, BMW started selling MY 2011's in the US in March of 2010!

Yeh VIN says 2007,one of those first i guess,lets just say 2008 if u like

EDIT : kscarrol knows it all

You got the car on March 2010 and it is 2011 model? Why BMW is using this way?

[kscarrol]

No, I took delivery of my MY 2011 in early October 2010 but BMW was selling MY 2011 M3's starting some time in March 2010...

Edit: Check out this thread showing production dates by model year...

If you feel the need to change them? Then get the WPC treated bearings or the VAC. They are both just as good as the other, so there's no need to "flame war" over it!
So go with what you like best?!

Congrats and welcome onboard!

Regarding the rod bearings you need to read in on the issue and make your own judgment before you make a decision. There is plenty of material to study on M3Post.
To add some balance - cause after all most S65's do run for a long time - don't forget to also read in the 100k miles + link.

Good luck!

I just find it absolutely ridiculous how you can buy a car of a certain model year up to 9 months before that year begins! IMO a car's model year should be the year it is built and sold.

I don't disagree! Just the messenger...

Castrol TWS is one of the best racing oils you can get. The problem is not its quality. What people hypothisise the problem to be is its too thick for street use, short trips to the grocery store, low speed stop and go driving. The reason BMW recommends it is most likely because 1) Castrol bought into it and 2.1) so it doesn't sheer down* 2.2) and can still lubricate with excessive blow-by with racing for long periods of time at high RPM's.

*it does sheer down from its original viscosity but stabilizes at a slightly lower viscosity.

So what if production date is Nov 2007 and it reaches the dealer in Jan 2008?

Your rod bearings may or may not need changing.

Getting an oil analysis during your oil change will help you decide if you need your rod bearings changed. I have the same miles as you and my oil analysis is still ok.

[mikusk]

I am few days before oil change,I am from europe,what should i look for in the analysis ? Can u guys recommend me any good labs for this outside blackrock since that is US company ?

I can't recommend a lab, but look for very high lead ppm. Of you see abnormally high lead content and/ or copper, might need consider changing the bearings. This is because the bearings have lead outer surfaces with copper inner surfaces. High lead high copper then big problem. Low lead low copper no problem.
