Oil change at 20,000 miles?!?

[Ferguson]

I think (emphasis on think) for a good while my oil change was saying 11,000 miles, I was a bit under 5000 actual, I figured that meant 15,000.

Today I noticed (with about 5000 miles on the car) it says oil change at 20,000 more miles on 7/2009.

20k!?!? I think that's 20K MORE miles? So about 25,000 miles?

Has anyone else seen it go longer than the 15k?

Am I missing something?
