there's a bunch of threads on this. you should try searching.
there are people who range from 3k miles all the way pass 10k miles. its really your choice and how hard your drive your car and in what condition. for me, i like to burn money and change my oil every time i change my filter, so approximately every 5k miles

With a good synthetic you'd be literally pouring money down the drain changing more than once a year.
This all assumes normal driving. If you're doing nothing but a bunch of short trips where the motor never gets to warm up I'd probably change it every 3 months with the cheapest dino oil I could find regardless of miles driven.

I've been doing 7500 on conventional oil (while my IS is under warranty) and dealer hasn't said anything negative.
I'm planning to do the full synthetic at 10K intervals soon, I'm curious as the possible lame response I might get at the Lexus service department. Already one service adviser mentioned the lame inspections at 5K when I mentioned it, therefore this is a service adviser that I will permanently avoid in the future.

quick question. so i have an idea that you can change your oil at X amount of miles. My question is what about the time frame?
I rarely drive my car. I think Ive put about 2-3k miles in the past 7 months or so. should i change my oil within a specific time frame? or should i just wait til i put 5k miles on it?

Every single UOA I've ever seen on a 2IS suggests that 7500 is very safe under normal driving conditions with conventional oil, and 10k is probably pretty damn safe with it too.

What about filters ? How long/miles should I wait before getting it replaced?
Also, do you just reset when "oil maintenance" light comes on without oil change ?

Then you've been changing a LOT too often.
UOAs have suggested they're good for a year... but if you're especially paranoid you can go with 6 month/10k filter changes without changing the oil itself (which should be a 1/yr affair with a good synthetic)
Yup... the light comes on based on mileage, it has no idea what condition your oil is actually in.
Depends on how you are driving it.
If that's 2-3k miles made up of a bunch of really short trips I'd be changing every 3 months regardless of mileage.
If that's infrequent longer highway trips where the motor gets to run at operating temp for a while each time then I'd change it once a year with no regard to mileage.
As always UOA is the only way to be sure you're doing the right change interval for your specific driving... but those should be pretty safe guidelines generally.

The newer engines don't follow the traditional oil change schedule. I still remember when I bought my first car in 1997 and the dealer said first oil change is 1k/1mo and then 3k/3 mo. This is conventional oil. Now, what I hear from dealers is 6-7k/6mo on conventional oil because the newer engines are running cleaner and more efficient.
I go by mileage because I get the most out of my oil from my hard earned cash.
