I've been using Mobile 1 for a while now, just did an oil change this week. There's a lot of controversy over it though.

The slippery kind
. I use Mobil1 cause I get it free. No its not stolen. But I have heard of people switching to Mobil1 and having oil consumption problems. I haven't had any problems in 20,000 miles of it. So use with discretion...
How long do you think the filter is good for though?

I just switched to Motul 5w-40 full synthetic, mainly because I am using their gear oil and am very happy with the results. Does it matter? Probably not all that much, let's be honest.

i swapped from motul (was down a quart after 2500 miles) to mobile one. dont know how i feel about it.
ALWAYS ran rotella t in my motorcycles. they loved it. shifted smoother (gears are in the motor oil) ran quieter.
now that i run synthetic.... how bad would it be to swap to rotella t?

Different oils work differently in each individual car. The best way to find the oil for yours is to try a few out, and send in samples to Blackstone Labs. You're not going to "damage" your engine as long as you use name brand quality oils.
Like someone has already stated in this thread, Mobil1 is known for oil consumption issues but they aren't limited to subaru. Mobil1 is a very "thin" oil, try putting some in a cup next to say Rotella T "thick" or Amsoil "medium". They both may have the same "weights" but their formula at room temp has a different "thickness" to it. I'd call it viscosity, but that term would pertain to the weight (5w-30 etc..)
I would stick with the factory recommended weight for the testing. I tried Mobil1, Motul, and Amsoil. None of the oils did poorly at all, but out of those three my engine seemed to like the Amsoil best. Combine this with my hatred of Mobil1 hehe and needless to say, I'll be running Amsoil 5w-30 unless I find something else that works well. The next oil I'd like to try out is Pentosin 5w-30. It's a European diesel oil that I had great luck with in my VW/Audi high performance apps.

just an FYI, diesel truck oils generally have higher API service ratings than gas motor oils. This means they're a better quality oil with less shear and the ability to withstand a lot more abuse. Rotella is a great diesel oil, but for gas engines it seems a bit thick for me. I'll get that Pentosin coming and see how she likes it. It has a consistency very close to castrol syntec, but carries that higher quality API service rating suited for diesel and is a true full synthetic, not a hydrocracked semi-synthetic like castrol syntec.
