Currently at 87k on my Focus.. Only problems have been alternator woes.. I use 5w20 Valvoline full Syn. Probably should have a transmission shop do some kind of cleaning on my transmission. You guys think I can maybe get 150-200k outta the car if properly maintained. Will be around 140 miles a day. Own a house in a small good town to start a family in, and worth the trip. Not a lot of work for what I do there though.
