I never drive anymore = when should I change my oil?
 

Now that my car's in Tokyo, I think I've put a total 1500 miles on my S4 in the last 12 months. I haven't done anything except to put in an additional quart of Mobil 1. (AWE Stage3)

Now I'm at the next minor service interval - should I change the oil or let it be?

m.

I change oil at least once a year in this situation.....
 

IMO, you may also want to change the gearbox oil and the brake fluid at least once a year instead of the normal interval now, because with lack of use, you may actually have more moisture accumlation with those two systems. This is the schedule that is usually recommended for collectables with extremly low usage.

Then what type of oil is best: syn, blend, or regular?

What do you think? you bought a Biturbo V6, not a Ford Festiva.

Festiva = Party in a box!

Synthetic with correct oil grade. Make sure you at least start the car up once a week...
 

and drive it at least once every two weeks. Remember, there are a lot of moving parts on a car. If you let it sit, the rubber will dry out and metal can fuse. Another thing, get a battery tender or disconnector to preserve you battery's charge/life as much as possible.

I agree with 12month changes.. Synthetic vs. blend seems to be a legal question these days..

400 miles in the last 12 months at max .. Woot Woot
 

wrecked car : P

i would do it every 6 months.
