They say you are supposed to change your oil every 3,000 miles.  I change mine closer to every 8,000 miles and I had a mechanic friend of mine tell me that is OK.  He said the “every 3,000″ oil change is a myth.  Here is a $10 off Firestone oil change coupon.  You can go to the official site where this coupon was here:  http://west.completecarcarecoupons.com/Campaign/BF675/OIL.html    As far as oil changes go, I think Firestone and Jiffy Lube are the top two in my book.  But always make sure you go there with some sort of oil change coupon because paying full price for an oil change is no fun.  We’ll see if we can dig up some other oil change coupons and post them later on for you.  For now, enjoy this Firestone oil change coupon for $10 off.
