Mobil 1 0W-40 in a 2004 WRX

Thought of doing it. I heard something about the possibility that
Mobil has gone to different base lubes in their North American
offerings, save their 0W-40. I also tend to go a bit longer than
severe intervals along with most short trip driving in cold temps.

I live in the San Francisco Bay Area, although I may go into the
mountains. I don't know if this interval is going to extend into the
winter months when I might visit Lake Tahoe or Yosemite.

I figure this should be OK. I hear Subaru uses 5W-40 oils in the UK
for the same engines.

Also take a look at the Synth Rotella in 5-40.

You might like reading the forums at www.bobistheoilguy.com , And see if
there are pertinent used oil analyses (UOA) on the oils your interestd
in - maybe even in shaky town!
