I just changed my oil at 10k (2nd change, 1st for me). I used a 5 quart jug of 0-20 Mobil 1 and a Mobil 1 oil filter. I filled to half way on the dipstick markings and I have enough left over for another oil drain and refill in 7500 miles, leaving the filter there until it has 15 k miles on the filter.
This way it costs me about $18 per oil change, $36 every 15 k miles. We'll see how the oil holds up for 7500 miles.
regards
mech
