I went to the service station today. A oil change, (Filter, 4 quarts of oil, washing windsheild, and checking lights and wiper blades) cost me exactly $30 dollars and some odd change. The high engine oil was like $45. I stuck with the low version though. I'm taking your advice and I'm going to change my oil the next time! I know I need an oil wrench and of course the filter and oil. I'm curious where I can dispose of the oil after I'm done. I know some places charge you a few bucks to do this, but I would think they could somehow recycle it and should be paying the person recycling.
