Why you shouldn't trust people who tell you mobil 1 sucks? Because they are the same people who tell you its normal for the subaru to burn a quart of oil a month.

I've used mobil 1 on all my subies, never had an engine problem, my subarus have never burned oil.

Why should you trust people who tell you Mobil 1 sucks? Blackstone Labs and their UOAs.

I don't want to start another oil war, so I'm just going to point out observations. Rotella T6 has proven time and time again through Blackstone UOAs that it can be in our motors for 7k miles no problem. Mobil 1 has a tendency to shear down to a 20 weight in the turbo Subies. If you change your oil every 3k miles, then I don't think it'll be a big issue.

I'm lazy, however, so if I can get 7k miles out of Rotella T6 for the same price as the Mobil 1 and there are no cons to using it, I'm going to use Rotella.

If you change your own oil just experiment and see what you like. Try Mobil 1 and if you don't like it switch.

Total oil, subaru filter. I have used chevron and shell before. If you swap out right at 3k, not too much of a difference.

Amsoil Euro 5w-40 with OEM filter

I've gotten 2 UOA's so far on the Amsoil and a third one is going to be sent soon. It's been looking good so far.

I've mainly used Mobil 1 5W-30 and I haven't had any real issues. It does burn a little bit of oil, but I check it every time I pump gas so I don't mind.

US market mobil 1 formula is not the same as the rest of the better quality mobil 1 out there,just fyi. I have noticed I burned about a quart an oil change with mobil 1 in the past, other than that no engine problems.

I now just use Rotella T6 and change regularly around 4k.
