I just picked up 24 quarts of Havoline, which I will probably use on my Mercury. It has 70k on it and doesn't use any oil during it's 5k oil changes. So I have no problem using the Havoiline for the next 20k.
My wifes Merc has almost 78k on it and uses probably .5 quart during it's 5k oil change. Would you consider this normal useage? I was going to go pick up another 24 quarts to use on it. Would it be wise to switch to a high mileage oil? I've onwed many modulars over the years, just wanted to get some of your opinions before I head back to the auto parts store in the next few days.
