Question about 2004 Mercury Mountaineer
It is possible that when you had an oilchange the oil used was 10/40 which is correct for this vehicle BUT i would advocate that a thicker oil is used for this mileage say 20/50.
all cars will use/burn oil and i always ask my customers how much oil they put in from the last service so that i can judge what oil to use.Thin oils (5/30)should only be used for new cars,and even then
keep an eye on oil usage/burn.....
We have all read,in various publications that "using the wrong oil can cause damage"but after 40 years in the trade,i have NEVER had a complaint or any engine damaged by this method of filling
at service.(we had forty bays in my last dealership.)
