I change mine once a year in the spring after it comes out of hibernation. Its an 05 with less than 30k miles on it, tells you how much its driven each year.
i change my oil filter at 5k an top off will mobile 1. after 10k i change everything. never had a problem with any of my vehicles. my old civic had over 250k miles on it.
Swap mine every 6 mos even if it has only been driven a few miles. I run breathers so it is not very efficient at actually removing fuel and and moisture from the engine crank case. that stuff dissolves back into the oil so i change it more often than most. every 3K miles or 6 mos, whichever comes first.
