Second Oil Change & Tire Rotation

Went to Pacific Ford in Long Beach, CA today for a oil change and tire rotation. I took in 6 quarts of 5w 20 Mobil 1 oil and a Mobil 1 filter. Was charged $12.60 for the labor on the oil change and $20.00 for the tire rotation. Total bill $32.60. I'm a big believer in Mobil 1 after having used it exclusively on our last car. I'm going to attempt changing my own oil next time as it appears to be quite easy. Now averaging around 19.5 mpg over all. No problems to report.
