Hi everyone!
This forum is such a treasure of experience to learn from!
So to my question: my wife and I are planning on getting a popup camping trailer and towing with our Forester (see sig). It'll be close to the 2400 lb limit. Anyways, weight is not what my question is about (I've read lots of threads about towing and weights), but it may affect the choice of oil.
We'll be towing in all kinds of places, including deserts in Utah/Arizona, but not always that hot. Also a lot going to the coast and back (over the Coast Range). I'm sure sometime we'll be going over the Rockies.
So I found this in the manual, page 11-12:
P.S. - I plan on putting in synthetic, if it matters.
One more related thought - For the 5MT, I assume I don't need to worry about tranny oil; stock should be fine. Is that a good assumption?
Thanks much!

I'm wondering what y'all use for towing, especially if you tow a lot, and/or with high heat or inclines. Subaru gives a lot of different oils to choose from, and I don't know if the 20W-40's enough or if I should go with 10W-50 or 20W-50. Also, what about the classic standard 10W-40 (not on the list)?- Recommended grade and
viscosity under severe driving
conditions
If the vehicle is used in desert areas, in
areas with very high temperatures, or is
used for heavy-duty applications, use of
oil with the following grade and viscosities
is recommended.
API classification SM (or SL):
SAE viscosity No.: 30, 40, 10W-50,
20W-40, 20W-50
P.S. - I plan on putting in synthetic, if it matters.
