Ok, well just as a general perspective just because a smell goes away is not necessarily indicative of the problem going away. And you clutch wont go out the first time you ride it but when you are shifting avoid dumping it on your launch. Also avoid slipping it out at high rpms, there is kind of a happy medium with AWD cars. Look around you will find many threads, youtube videos etc. on this. And yes you use fully synthetic oil. I think my local Subaru happens to use Mobil 1 fully synthetic, and if you feel comfortable doing your own servicing, power to you! Personally I have a maintenance package until 60k you may want to check with your local dealership on what kind of deals they can cut you.
