Hi folks, Couldn't find much info on this, so hopefully not a newbie question. I've always run Mobil 1 in my newer vehicles, and Mobil Super 2000 High Mileage in my winter beaters. I do 10,000km intervals with both. I recently purchased a 2010 Liberty with the 3.7L motor and 195,000km on it, and I'm wondering if there is any benefit to using the high mileage oil vs the regular full synthetic. Thoughts? Thanks!
