Re: Oil change interval ??
I usually go by my oil pressure. I can tell by the pressure reading when it is getting bad. The oil life things tells me to change it when idle pressure is at 38-39 psi hot. With fresh oil, idle pressure is 43-44. I usually change it when it gets to 40-41.
Mobil1 Synthetic all the way! Some things you shouldn't skimp on .. and engine oil is one of them.

I change it when I see the color changing. Like a darker brown usually. I don't go by milage. That oil life monitor is off usually for me. That happens 4000-5000 miles usually
I like to run Mobil 1, it goes in the WRX. I use Valvoline 5W30 in the Z, and 20W50 in the ol' Blue Oval as the rear main leaks...

I have noticed the Mobil1 is a little darker to start with, so I don't know how reliable the color method would be with that.
I used the Oil life once, and it was BAD looking when I did change it.

I run way too many highway miles to change it every 3000 miles. I usually go 6-7000 miles on Mobil 1 10W30. I can tell when it's time to change by how loud the tapping noises are.

Mine averages 3800 miles. If I'm on the top end of that and have been playing hard, I'll change at 3k. If I have been running mainly highway miles, I'll go 4k - 4.5k Mobil1 5w30 year round and A/C PF59 filter.
