it wasn't required for the warranty? we have a 97 and it came with synthetic in
it; and it was a requirement for the warranty....

I'm getting ready to by a 2004 Forester XS. I will be installing the
following as far as lubricants and filtration after about 2000 miles.

Automatic Trans:

Differentials: (I'm assuming they are not sealed)

Engine:

Air Filter:

I assume that I will get a significant improvement in fuel economy as
I did with out 98 Dodge Intrepid. 31 to 32 MPG's HWY over stickered
28 or 29 MPG's
(Can't remember)

I'm excited to own my first Subaru. Been test driving Honda's CRV and
Forester and the Forester wins hands down!

Living in Ottawa. I've used synthetic for the past 5 years in my last car
and now my subaru. Makes a noticeable difference in -30degrees Celcius cold
starts.

Don't notice any other benefits, but that alone is enough for me to bear the
extra cost.

Hi,

Over the years I've tried Amsoil, Mobil 1 and Castrol Syntec. They all
have their benefits over dino oil. Fuel savings of a "significant"
amount were not one of them. Best I saw was about 2.5% on long trips. On
a 25 mpg vehicle, that's all of ~0.6 mpg. "Normal" driving returned from
0% to maybe 1%. Any of these numbers are well within the range I see
with weather changes and other variables, so I never put much stock in
the claims of better mileage.

But... this is where YMMV originated! Every engine, every driver, and
all our driving conditions vary, so you MAY see much better results.
Please let us know!

After changing several cars (engine/transmission & differentials) I kept
track of mileage for ~ 1000 miles and found only about 0.5 % increase in
mileage.

Cold climate operation strikes me as the most compelling reason to go
synthetic. My only reservation is that now, with my turbo, will synthetic
prolong engine (especially turbo) life? If so, is the savings from prolonged
life greater than the extra cost of synthetic?

Re: Cold climate operation - I agree! - I can't stand the sound of an engine
struggling to turn over. Makes my teeth ache.

As far as prolonging life... Don't really know if there is an answer to this
one. My last car (86 Honda Accord) - was running strong at 365000kms - The
majority of that was dino oil.... I changed to synth late in engine life -
and no, I had no problems with leaks, as can occur when changing to
synthetic in a high mileage engine.

There's also lots of people out there with extremely high mileage engines
who have always run dino oil only. And of course, same goes for synthetic
oil users...

My personal opinion: Regular maintenance and oil changes are the secret for
long engine life. Use Dino oil or use Synthetic. Just change it regularly (I
change my synthetic every 5-6000 kms).

As far as your turbo is concerned, I'm fairly sure my dealership recommends
synthetic oil for the wrx... don't know what the owner's manual says though,
and don't know the reasoning behind it...
