My father drives around 1,700-2,000 miles a year. He's getting on and mainly putters around town and occasionally goes to doctors app'ts, the drug store, home improvement stores, etc. He has a Vulcan '06 Taurus and the oil is still pretty clean and full at 1,700 miles since last July 19th when I changed it using a Drive Works filter and (mostly) QS Defy 5w30 blend. I was thinking of doing it around either August 1st, Sept. 1st, or October 1st. Now I'm toying with the idea of leaving it in there until Spring of 2017! Crazy talk for me even a couple years ago. But is seems that some are going up to two years on OCI's without issues. I do worry a bit about his short interval driving, but he does take it out for much of the day here and there so it does get heated up.
When should I change it? Planning a "Frankenbrew" of mostly (Havoline) Full Synthetic and a Motorcraft filter next time. I worry a bit about condensation, but there doesn't seem like a pressing need to change it. What do you think?
