I've used Mobil1 5W-30 several years in a GMC truck and already bought a 5 QT jug for my new 2004 Outback Sport. Will make the change sometime this week after a Fumoto oil drain valve is delivered. Should be 1500+ miles on it by then. Starting 2nd month after tomorrow!

Hadn't mattered before but the Mobil1 5W-30 says "New Car Formula" on it, which is a little reassuring as I do this. Checked and found it "meets or exceeds" GF3 specification Subaru says to put in the OBS.

My mechanic (I hope he's a good one, he just did my HG!!!) is suggesting a 10W-30 (10W-50?) for my 2.5 L running in the WINTER (in the Northeast).

This runs counter to how I was raised--I thought I should be using a 5W-30 for the winter months up here.

He wants to check my engine and change my oil out at about 1,500 miles after the HG repair (seems sensible), and I was wondering if his viscosity suggestion holds any weight. I've got 10W-xx in there now, from the repair.

No, you want 5w-30 or 0w-30 for winter. 10w-30 or higher is going to be very thick in cold weather

Keep in mind, all 3 of those oils will be xx-30 when up to temp, but you want something thin during a cold start which is where the 0w/5w-xx comes in.

German Castrol

Run German Castrol Syn 0w30; states European Formula, year round...good for cold starts in winter and runs thicker for protection during the summer......if you watch, you can get this on sale at Auto Zone for the same price as the regular Castrol 5w30 syn.....a lot of subie owners run this GC in their turbo application, I like it in my non-turbo 3.6 for added protection, expecially since I keep cars at least 10 years.......

A 10w-30, PAO based synthetic (Amsoil, Mobil 1, etc), will easily pump down to -40F/40C. So you're certainly not restricted to 5w-xx and 0w-xx grades.
