Hi new member. I have a 2011 Jeep Wrangler with 17000 miles on it. Just had the oil changed at the dealership. This was my 5th oil change at the same dealership that I bought the jeep at and every time they always seem to overfill with oil,I have brought this to there attention but to no avail.So I guess I will be doing my own oil changes from now on. I would like some input to what oil(syn or dino) which brands ond which filters.I only plan on changing oil twice a year. October 1 and April 1 so iguess I would be looking for a good Syn oil.I do not wont to be caught having to do a oil change in the cold of Boston in Dec, Jan, Feb doing 3000 mile oil changes as I have no garage. thanks in advance for any help and suggestion.I normally drive about 8000 to 10000 a year, mostly highway.
