Oil is cheap enough Swaitsy.
I've never gone as much as 5k between changes, but I only do about 1k a year these days so I just change it every year.
When I was working I used to own a Trans-Am and when I changed it's oil I would use it to do an oil change on my van, haha.
A regular oil change keeps every thing clean.
My 2009 A6 has only done 42k.
