What brand oil and weight are you using and how often are you changing it?

I only do dealer service at this point. So it’s 0x30W synthetic, I think. Due to the extreme mileage I change it at 5k intervals.

“What brand oil and weight are you using and how often are you changing it?”

My first thought as well - consider bumping the oil weight a bit.

Of course it may be simply that your oil level is a bit down.
