I used it for one cycle, but it just didn't seem to help out like they said. If you just keep the oil and filter changed regualrly, you shouldn't need it.

I have 160k on my 89, and I use regular 5w30 and 10w30 Pennzoil. I leak oil from the rear main seal, but the car is about a pint low after 3,000/4,000 miles, so I don't want to deal with it except I can't park in the driveway.

If you use a lot of oil, get smoke after the car is warm and you gun it, then maybe, it mainly helps with valve seals, maybe with gaskets and other seals too. I didn't replace the valve seals when I did the head gasket, and it doesn't smoke at all except after my wife babies it for 600 or 700 miles and I start driving it again, but that isn't oil.
