Our cruiser seems to be using some oil when the dealer did the oil change it was filled half way up the safe range and it almost 1800 miles it's used Down to the add line. So half a quart in that time. I'm not overly worried being a saturn owner I understand some cars just do it. However if there is a way to fix it im all for it. Is there anything that could be causing this? Any common issues on these engines that cause consumption? Thanks everyone.
