Just following up. Ended up taking it to Beyer Subaru for the mid-tier service level (car currently at 75k). Mentioned the oil consumption and they dismissed it as normal and seems to be based on feedback. I just thought Syn lasted quite some time and could last at least double the normal oil change interval of 3k. I will monitor the actual mileage this time to see if I will need to replace the oil at excess rates. No complaints else wise other than follows...
Now one thing that irritated me, not anything from Beyer, but my wife just had the car in at 70k for an oil change and PA state inspection back in June (2-3 months ago) at the normal dealer and where she purchased it new (Lancaster Co Motors). The service guy at Beyer called us to report the front tires need replaced and aren't even safe to drive on and the rear pads are way low (1.5mm). I was like
. Showed me the pics on the report because I looked at him weird at pick up and sure enough the inside of the fronts were practically bald with metal about to poke... I didn't notice it myself because the wear was on the inside and I've never lifted or worked on wife's car. Also, how did the tires and pads pass inspection less than 3 months ago!? I knew we were going to need to replace soon, but I didn't realize the extent based on previous check.
A few other things that this has spun in my head, what were they actually doing for my wife's car when she was taking it to LCM? Since all of her maintenance has been done ritualistically there, I wonder if they just started taking short cuts knowing she'd be back? I like to replace pads 2.5-3mm, and usually thats when you are notified of replacing. Anyone experience 1.5mm+ of pad wear in ~5k miles for light, daily driving???
What variance in front to rear tread life is there usually? The tires don't seem to have been rotated properly based on mid status rears and dire status fronts. And inside tire wear like that seems like alignment is off... unless anyone can confirm this is normal for AWD fronts? I'm still building my knowledge base on my Impreza and her Legacy, usually as I go through the work on them.
Anyway, the past is the past. Ordered all 4 tires from Tire Rack, 5 star rating all-seasons, Posi-quiet pads, and the simple centric rotors. Just going to have Community Car Care (great reviews and easy inspections when we moved here) in the local area do the work. Don't have the place and minimal time and the wife is being weird about me working on her car, even though I've done everything to mine
Would have liked to just get winters at this time (and summers in the spring) and some Hawk pads, but still recovering from the wedding back in Aug. Next year! Thanks for replies.
