I have a friend that owns a gas station/repair shop that after they change oil in customers cars they take the quart bottles and turn them upside down and let them drain into a large container he has cam 2 5w20 5w30 10w30 wolfs head mixed weights and conoco and some mobil 1 synthetic and who knows what else.. He uses this in his own cars and has been doing this for a number of years.. He does not waste a drop of oil.
All his cars run very well and most have high mileage he has a 2002 Lincoln town car with 201,000 a 2012 chevy truck with 24,000 miles and a few other vehicles that his kids drive and they all run great. He also uses cheap jobber filters whatever he gets the cheapest. He says oil is oil and the cheaper the oil is the better.. But on the other hand he wont buy parts from advance auto or auto zone because he thinks they are junk.
