What mileage was on the focus? Also, previous oil change history would be interesting.. in other words, has this vehicle broken in already and if so was dino used frequently during break in?
The mileage at the time was 14,713 miles.
This was the car's fourth oil change.
I changed the break in oil out at 570 miles.
Then, around every 5000 miles after that.
I have been using M1 5W20 since the first oil change.
That run was with a Wix filter (51215) and I think I am going to go with that filter from here on out.
Petro oil would give you the same or better wear numbers. 5,000 miles with M1 has no advantage other than sending $$$ to Mobil
I plan on going on to longer intervals, starting with this run. I am going to 5500 miles like suggested. Eventually, I want to go to 7500 miles. I don't want to switch oils then, this is what I plan on running until the car hits the grave.
