30K throttle service

Dirty oil means that dirt is not on the internal engine parts.

Better to judge when to change the oil based on milage on the oil, time too if you don't drive so much....also driving conditions, for example if you take a lot of very short trips, change the oil more frequent.

I agree with you Pavel...looks aren't a good judge of oil. I change every 5k because I'm looking for this car to reach retirement (I'll have at least 150k on then, 5 to 6 years), and I won't judge people wrong for going 15k between oil changes. I just don't think the Throttle body requires regular service (just like carburators didn't) until the performance shows it's needed. I've driven too many FI cars for 200k without the TB causing any problems.
