Well what do ya say if we say the hell with oil and we all get a horse and tie our license plate to his tail...? but then we would have to carry a dang pooper scooper! I learned early on that the best mechanical fixes are the ones that don't cost anything. Checking the basics first and keeping it simple without spending hard earned money for parts not needed and your car, meanwhile is still parked on the front lawn as a monumental reminder. Here is one good tip forgotten by many. The word is "Vapor Lock" I find this happens often and to test this is to loosen your gas cap for sucking of air then put your cap back on. I hope my Gripes, Rant, and Yelling helps someone out there!
