Oil Amount?

I just changed from Dino oil to Mobil 1 synthetic today. Wow what a difference on the smoothness of the engine. The owners manual called for 5.7 quarts of oil, thats what I put in. The amount that drained was less then 5 quarts. I had my last oil change at the dealership. Did they just short my engine? It was only about 3k miles since the last oil change and I had not towed or hauled anything. Does the engine eat up that much oil or did the dealership just short me?

Thanks

 

the 4.0 takes 5.5 quarts of oil, so just keep an eye on it. getting oil changes done at a dealership are hit or miss.........they may have just been slack.

 

Thanks for the info.
