I change oil every 5000 miles or 3 to 4 months no matter how good the oil is and I use mobile1 every time. Car seems to run smoother and last longer with regular oil change. I also change oil in my work minivan which is Hyundai entourage with about 130k miles now. I used to change oil every 5000 miles but now with high mileage I change every 4000 miles. I can definately tell the oil is going bad around 4000 miles cuz car runs like a shit. Yea I know it's Hyundai so it's shitty car to start with but it's so much smoother after oil change.

My dad gets his oil changed about every 20-30k mi on his bmw's. He has gone up to 38k w/o a change. He maintains his cars about as poorly as anyone can. Nothing gets fixed/serviced until it breaks.

If the oil often doesn't get to temp, it's going to degrade much more rapidly. If you simply drove on the interstate constantly, a good synthetic would probably last an easy 25k miles (filter a fraction of that). But if you do many short drives like I do, it's going to get moisture in your oil more rapidly. My commute to work is about 4 minutes and less than a mile and a half, others are probably similar if they purposely live by their work.

Amsoil is good stuff, but you might want to check and see if they recommend a filter change during that period.

bs...I challenge you to get a UOA at 15k (or even 10k), unless you're using auxillary oil filter, it will be shot
Sorry, but you lose this one.

My dads BMW 330i has lifetime transmission fluid, and guess what 180k miles later its still sloshin around in there with 0 mechanical problems. I must say thats impressive for an automatic transmission.
