New-2006 Fusion questions...

greetings......

New owner--
1. What is the best oil for this engine?
2. Recommend what car cover seat maker will fit for side-impact bags..(car has non-leather and blk interior)
3. Brakes feel good after some breaking in...only i do feel a bit of pulsating (slight) after slowing down from 70mph--is this normal???

4. Personal question--should i take my dealer to court after not honoring full/ineterval oil changes as long as i own this car...I have this in writing and signed by the salesman on the contract. This was part of the deal. When pciking up my car the salesman was on vac..So i briefly spoke with the manager (small talk) about the service--blah-blah....He said the salesman had no auth. or right to do this.....he was willing to give all my funds back...the manager knew i needed a car since my ford probe gt..was finished....He would give me 2-3 oil changes.....
Personally i never heard so a bunch of crock/b.s....
Calling ford in Michingan was no help......i did make a complaint.....plus i stil haven't picked up my second key....i think they lost it...another story...i would to go into service and make time again..

Any answeres/solutions would be helpful.

thxs.
