So I checked the oil today on my 2017 Yaris iA. As I wiped off the dipstick I noticed a grayish residue coming off it in addition to the oil.
I've never seen that before on any vehicle I've owned.
Anyone know if this is normal?

I have that too! Was wondering the same thing!

Still can't find any info about this but in my opinion it can't be a good thing...
