Coon man has 10 dollar oil changes? What is he using water for oil ad a roll of toilet paper for an oil filter? most Vehicles use 5 quarts of oil at a minimum.. at 2.50 per quart thats 12.50, add on a 5 dollar oil filter. that brings the total to 17.50. Now you get to figure time is money. at 10 dollars an hour and about an hour to do it yourself, you are looking at 27.50 for that oil change.
