M1 EP 5w30 20,500 OCI, Toyota 2TR-FE Fram Ultra W/TBN

Wow! They recommend going 22k miles next time! While the data suports that, I am way to uncomfortable going 22k miles on an oil. I don' think I ever went further than 10k miles.

Is your Speedo/Odo corrected for the tire size?
Because if not, then your run is actually ~1500-2000 miles longer than odometer reading, between stock tires and 33" tires.

The oil did fantastic. 5W30, a great choice as well. Nice report!

Some engines can handle long runs on EP, but some shear oil pretty badly due to VVT-I, long timing chains, etc. and can’t go forever on an OCI. It would be somewhat dangerous to extrapolate this one to other engines, even Toyota ones. I know my xB wouldn’t be able to run more than 10K on the same oil, although there was very little contamination, wear metals, or carbon in the filter. The oil just physically couldn’t take it.

When I look at the UOA of the Mobil 1EP, I don't see anything remarkable so the outstanding performance must be from the POA base oil? Ed
