While I still continue to have them supply my oil, the cost does seem high. The dealer charges almost $62 for 7 quarts of oil, whereas it appears I can get 5 quarts for $20 (but I guess that still is a little short of the required amount of oil).

Question: Is Castrol GTX Magnatec OW20 always fully synthetic? I just want to make sure they used fully synthetic.

Yes. It's the cheaper full synthetic from Castrol. The other is Edge Advanced. Castrol, Valvoline and Mobil all have good ratings. My car's almost at 75k miles, so I will use the high mileage version. I might even try Walmart's brand? Whatever you use, it should be 0w-20 full synthetic.
