Faults:
At about 58000 miles, the engine was leaking oil. I had just taken it to the dealer for a service (60000 mile) and they said nothing about it. If a conscientious quicklube mechanic hadn't mentioned it, I wouldn't have known until disastrous damage would have occurred. I took the car in to the dealer and fortunately, the powertrain warranty was good to 60000 miles - 2000 more miles and I would have been out of luck.
The dealer "fixed" the leaks... after a week of sitting in the shop. Driving off the lot, the gaskets began leaking. I drove it back on the lot and left it for another 2 weeks. Finally, after a new head gasket, the car wasn't leaking.
A little research online revealed that this is a common trouble with subaru engines. I thought the H6 motor would be utterly reliable - and I must admit it ran well in spite of the gasket trouble.
An alternator went bad at about 65000 miles, the rotors warped, the passenger side window (motorized) refused to work and the glass fell off the pane. The air conditioner stopped blowing cold air due to a leak in the system (new compressor needed). The transmission started to leak, and then the engine started to leak oil again.
Many thousands of dollars of work needed to get the car back in tip top shape... forget it.
Do yourself a favor. Don't believe the consumer reports hype about the Subaru outback. Research it yourself and find out why this car is a money pit.

There is no additive to stop a head gasket from failing. That's just the normal mileage for them to fail. It is a regular, known problem with these engines.
