I once had a 1992 Ford Escort wagon. I got 123K miles on it and only changed the oil once at about 65K miles. The engine ran like a champ and was getting over 36 mpg on trips just before I sold it. I loved that little car.
But admit it, you were adding a quart every 1000 miles or so. It simply isn't possible, even with the best oil for there to be ANY oil left in the crankcase after 65k miles. It will break down and boil off.
We still have a 1992 Escort LX we bought new. I changed the oil when I got around to it, but I did use synthetic or synthetic blends in it. It now has 322,000 miles on it and it’s the original engine. Other than a puff of smoke when starting and burning a quart of oil every couple of months, the engine runs great. But I think this may be the year we part with it.
I change the oil on my '09 Toyota Sienna every 5000 miles. That's what it calls for and the vehicle is under warranty. I don't want to screw that up.
I had an '89 Ford Ranger that I drove the wheels off of. I never changed the oil in it. I only added oil when it was low. It was beat-up as you can imagine, a perfect A to B work truck. Ran like a champ. Had to sell it when I moved. Sure miss that truck!
