I have a 2002 ford escape 3.0 that is about to reach 160,000 miles. I have been running 5w-20 synthetic but it has been leaking a bunch lately. I am debating whether to move up to 5w-30 synthetic or run a 5w-20 conventional or high mileage oil. It looks like 5w-30 used to be the spec for this engine but then ford changed it to 5w-20 a while back.
What would you guys do? I am trying to minimize sludge as much as possible. I bought the vehicle used at 146,000 miles and it was abused to [censored]...
