Went to Wally yesterday and they were zombieland dead. Asked the manager if he had time and he said he would do it himself. Went ahead and asked to try the oil flush. It's not a solvent and it runs for 10minutes idling. I got to watch and I asked him to drain vs siphon and gave new crush washer. Enjoyed being able to watch and he said nothing bad came out when the drain was pulled. Fram Ultra 7317 and 0w30 Mobil 1 back in. All in all, not a bad experience. He said I take really good care of my car and enjoyed seeing high mileage cars without leaks and clean undercarriage. Current mileage at 231,583 miles.
