I'll probably use synthetic oils even if I don't use extended OCIs after the warranty period is over.
The reason is my dealerships charge $90 - $100 for oil change, tire rotation and inspection.
I do all this myself. Compared to $90, I can use a top-grade oil and filter yet still save $60. Its true I could save another $10 with conventional, but I blow through $10 weekly just going out to lunch. So the cost differential isn't that much when I find synthetics on sale (which is the only time I buy them).
So, while some consider it a mortal sin to use an oil less than its full capability (ie 10-15k miles), I look at it as cheap insurance to buy the "good stuff".
Once I get tired of crawling under the car I may extend the OCIs. Since I enjoy maintaining my cars, that may not happen.
