HI, this is not a question about a mechanical problem or any other problem, but a question on maintenance to avoid problems. So I just bought a 2003 expedition, with 120,000 miles. Its an Eddie Bauer with a 5.4L engine, car runs good and everything, but I want to do a tune up, so I just want to know what would be the BEST spark plugs, that will give me a good gas mileage, and extend the life of the engine, also what kind of oil should I used, owners manual states to use Motorcraft Syntetic 5w-20, is this sill a good oil for my engine with the mile it has. I have heard that with engines that have lots of miles is recommended to use thicker oil. So I just want to know what is the BEST oil for my engine? BRAND? WEIGH TYPE? ( I live in Michigan were we sometimes get temperatures of below zero, I heard its a factor)I want to keep this engine running for a long time.
have the same problem?
