Some of the newer cars come with 3750 intervals now. But, with an oil change costing me around $20 its not alot of money savings waiting another 1k miles, so its up to you.
I pay $2.25qt for QS Semi Synth.

Most semi synthetic oils out there aren't even synthetic at all, they use 10% group 3 petroleum base oil. Mobil's semi synthetic is a true synthetic, but still only uses 10% PAO base oil.
The semi synthetic I run is called Schaeffer Supreme and it's about 20-25% synthetic and has proven itself to be a very long drain oil. I've seen results with this oil going beyond 10,000 miles. I ran my last interval to 4300 miles and the guy who analyzes my oil reports said to try 8000 miles on the next interval. This oil is only about $3 per quart, but yet it ranks right up there with the best full synthetics.
