Oil change interval

Ok. I am sure this will start a wild fire. But, how often do you change your oil? Owners manual says 5,000 miles is ok for light duty use. Anyone go that far non-synthetic?

How many of you have switched to synthetic and what flavor do you run and how far?

I always change my oil at 3k miles. Done that on all the vehicles I've ever owned. Turbo diesels like to kill oil!

Also, I run 15w40 Mobil 1 fully synthetic, simply because I get it for free. Seems to be good oil!

I go 5000 on Rotella 15/40.
If you cold start a lot it shears the oil more in the HPOP and needs changing sooner.
