Is the suggesting to switch to a high mileage oil at 75K an over sell just like changing oil at 3K miles?
My 4Runner is just over 150K miles and I consider it just broken-in. I would never consider a high mileage oil which such a new engine. The oil level on the dipstick does not move between oil changes. The only maintenance done so far had been oil changes and a timing belt/water pump/coolant change/brake fluid exchange/spark plug replacement at 100K miles. Oh, and a few air filters, too. And don't forget, one battery this year for my 2003 vehicle.
High mileage oil? Not a chance.
