I would use OEM ones myself. Just in case some sensor works off them. But I had a 2003 Impreza with many miles, the wires were fine and the car ran well.

I did not see Marvel Mystery Oil (MMO). I had a non Subaru with a noisy lifter years ago, added half a quart of MMO. still noisy, added the other half quart, noise gone forever. I have added it to all my small engines gas all my life now.

If you decide on using heat, just put some scrap sheet metal around/over the parts not to be cut off.

HVAC blower resistors have been failing for years, in my 2003 Jeep Liberty, in our Dodge Ram pickups too. So it is something that just fails. BTW, the resistor "works" the hardest when the blower motor is used on low speed. Most resistors when they fail allow the blower motor to run at top speed-high only.

I have a '15 Forester CVT with the readout showing 25mpg average over just 1000 miles.

It is illegal to do what you want, that is why they are like that.

I'd be more inclined to believe Volkswagen made the engine blocks.

I may be wrong but, the ABS system pulls quite a few amps when functoning. So based on that knowledge, plus the batt light to me equals the battery is failing. The 14.1 volt reading at the alt means it is working OK, the batt is prolly not accepting a charge anymore. The reason the lights go out on stopping is I THINK the ABS is not pulling amps while in "Park". Maybe a "load test" on the batt would be best, and go from there. Most auto parts stores will do it for you FYI.

Be interesting to know whether compression leak or radiator cap.

If the battery is indeed 9 years old, you are lucky. But the answers already given about an inadequate charge is my guess too. I have no idea where I came up with the 9 years old, I apologize for that mistake.

Anaerobic sealants cure when oxygen is taken away and have different curing rates, Here's reference link form Permatex: http://http://www.permatex.com/documents/tds/Automotive/51031.pdf

Steel rims can be beat back into shape, but then are usually just used for a spare. There are shops out there now that will repair an aluminum wheel now as well, a Google search will bring up shops throughout the country.

My wife always pays for the mid-graded in her Subees since 2000, and she says the cars run better. Who knows? I have a 2010 Fozzie, that "seems" to run a dite better with mid-grade than 85. I really haven't had the car long enough to evaluate the gas, and all my observations are strictly seat-of-the-pants, not entirely scientific.

My wifes' 2003 Impreza OB Sport had to have the HGs redone last summer if that helps in your quest for info. The dealer warranteed the work, after I squawked a little, and OK'd other work (brakes, rotors) to be done.
