Save your money and do it yourself! I do it myself in the garage, 15 min, $30 for 6.5L Mobil Synthetic and $5 for good filter (preferably Motorcraft or pure1) if you don't drive like a race car driver this setup is good for 10,000 kms+ though I change it every 5,000 kms since I am a oil change Nazi :p
