2008 BMW M3, Motul 10w-60, 6,900mi

This is a car I don’t get to drive often, so oil was in the sump for a little over 2 years. Pretty happy with the results here. But, due to the viscosity loss, I’ll probably limit my OCI’s to 5,000mi. This oil starts out at a 100c KV of 23.6cst. Rod bearings were changed changed at 85k mi.

Edit: forgot to add, no makeup oil added during the OCI. Only dropped about 1/4qt as indicated on the oil gauge.

Viscosity is well within range so everything looks good as expected with a Motul product.

Love these engines, and the v10, esp. Will have one someday.

Do you spend a lot of time with the revs way up?

Also, pls post pix of old bearings and the car itself if you get a moment.

IMO this oil is still usable. The wear is low too. Good run though.

Hey guys, I appreciate the feedback. This oil is a 10w-60 that has sheared down to the bottom half of a 50 grade. The BE rod bearings are spec’d for a 60, so I’ll probably end up planning my OCI’s around viscosity alone. Also, the shop that did the bearings (MPorium BMW…one of the best indy BMW shops in the country for this model) recommended this oil and 5k mile OCI’s.

Oh yes. High RPM as often as I can. lol

I have an Eventuri carbon plenum that lets those individual throttle bodies sing at 8,400rpm. It is a glorious sound. Very E46 CSL-ish.

Wow, very clean. Looks like a garage queen, obviously is not with the mileage.

Texas... lol (No rust)

Looks GREAT as does the UOA. Thanks for sharing.

Your viscosity is fine as 60 will shear down fairly fast into the 50 range.
I would though run 5k OCI.
