So I recently purchased a 2004 civic si and a couple of days after I bought it I decided to get an oil change. The oil I told Walmart to use was mobile 1 synthetic because the car has over 77000 miles, however, after only 500 miles the oil is a little more than half way mark. So basically should I just go with basic mobile 1 5000? And my car takes 5W-20 and they used 5W-30 does that contribute to oil loss?
