Oil Change Intervals [Expired Topic]

5000 at least I try to, with as many vehicles as we have sometimes its not easy to remember.

Full synthetic 7000 miles with Fram filter.

I change oil (Castrol GTX High Mileage) & oil filter (K&N) about every 5K miles sometimes up to 7K miles. If I go over the 5K threshold it doesn't bother me too much since I'm using a high quality filter, I figure it can handle a few extra miles.

I take it in to my mechanic every 5k. I haven't been to a quicky lube in years and will never darken their bays with any of my vehicles.
