Another sample from my 1987 4Runner, Wix premium 1515 filter, 3,003 miles on OCI with all in short trips and in town driving total mileage 303,391. You might ask why a MC oil? Well I bought about 22 gallons of it at 17 cents per quart several years back so it was cheap and it seems to hold up well. I have about 15 more reports to add for this truck that's still in service as my daily driver with the never rebuilt engine now at 314,5xx miles.
