"Oil's whether they be synthetic or dino have changed and improved by orders of magnitude from the time that the 3K interval was the standard. As has engine construction. Yet somehow the old myth of 3k is still with us."

Most DINO oils are gone by 3-4K miles, at least as tested.

Most "fake synthetics" like Castrol are gone at 7-*K

M1 usually makes about 11K or so till it is shot.

Red Line normally can make 13-15K tops.

I certainly do not advocate 3K changes with synthetic oil.

This is all a long way from 20K.

Reminder. Porsche is the ONLY manufacturer to make this recommendation. Are we to believe their engines are that different than others?

Hmmmm!
