Thanks Steven for all your recommandation.
I'm going to order the car this week with 205/55 16' tires.
In terms of comfort , I 've read that 17' wheels are not recommended.
Concerning the audio system , i'm a bit lost.There's a CD 6 in dash wich i
don't
really like , and Volvo doesn't propose a CD changer .
I'll see with my audio retailer wich solution we can find to add a CD
changer.
Best Regards
ART
Sure--best luck!!
I love the way the center stack looks on the new s40.
Someone else said to use synthetic oil--and that's a fine although expensive
idea.
I suggest Mobil one rather then Castrol because Mobil One is a true
synthetic while they do some hanky-panky with the Castrol synthetic--and I
have used castrol dyno (biological derived) oil almost exclusively since
well before oil came in bottles! (used to come in paper or even tin cans 1
qt or I guess 1 L --one needed a special 'tapper' to punctured the can.)
I think with the precautions I suggested you will be fine with conventional
oil, and while I admit my 3000 mile change interval is very anal, I am a big
procrastinator! If I aim for 3000 Miles I might get it done in 4000 or
4500! Yes stretching the changes out to 5000 miles should be just fine, but
7 or 8000 miles is too long, especially for a turbo.
A big issue with oil changes is how fast you rev the engine--and turbos have
impellers and compressors and bearings that spin real fast, and how long you
drive--if you take a lot of highway trips you might well go for10,000 miles.
I would not do it because the cost of an oil change where I get it is 20
bucks (US), and I watch them to help avoid mistakes, but even 30 or 35 bucks
is not too much if you go for a change every 5000 miles MAX with
conventional oil in a turbo.
Synthetic oil will allow you to be less careful about the precautions like
slow under 3000 RPM warm ups and careful shut down.
I will further admit that my slow and careful turbo warm up and shut down
procedure dates from back in the 1970's when turbos did not have a water
jacket as they do now--what USED TO happen was that the turbo was spinnin'
real fast (100,000 RPM) and ya shut the engine down.
The turbo kept spinnin' and gee with out fresh, relatively cool oil flowing
through it the oil got real hot and turned into coke or some such goo and
boom buy a new turbo time.
Now the water jacket surrounding the turbo bearings will avoid this issue,
and I guess one could just shut down with no precautions like I suggested.
In the end, it's your car, and your money. I reflected on my old skool
suggestions and well, I guess you do not need to idle the motor for a those
15 seconds before shut down to allow the turbo to spin down a bit, but I
would try very consistently to stay out of boast for the last mile or two.
