I use full synthetic (Mobil 1), but I change the oil every 5k miles. The oil can go a lot farther than that, but the oil FILTER can only go about 6k miles! Once the oil filter is plugged up, the filter will be bypassed and you will have unfiltered oil circulating in your engine.

I suppose I could let the oil go a full 15k and just change the filter ever 5k (topping off when I change the filter), but I choose to do both oil and filter every 5k.

I plan to hold on to my '07 Si for as long as posisble (maybe all the way to 300k miles), and the cost fo an oil change is small compared to the cost of getting another car. I am cheap, but I never skimp on motor oil or tires. I'll skimp on everything else, but not those two things.
