My dad just inherited a 2000 Ford Windstar from our neighbour with a 3.8 Litre engine and it has 276K KM (172K Miles) on it.
It consumes no oil and the engine is in perfect running order. It passed the emission tests with flying colours.
It has had 5w20 Motor Craft oil all it's life and has seen 10K KM (6K Miles) OCI's religiously.
It was given to my dad for some work that my dad did for him for free and because the van needs some other repairs like brakes, tires, exhaust etc...
Thanks for posting this! A lot of negativity on the board toward the thinner oils. I've been doing exhausting research on the topic both on and off the board. There's more to newer engine designs than bearing clearances, and the thinner oils are doing a fine job IN CARS SPEC'D FOR THEM. Remember the USA leads the world in tech, product availability, etc. There is more to this thinner oil debate than just CAFE. While we lead in tech we also lead in freedom to voice opinions, and use what ever we feel is best. YMMV
