I was curious what brand of high mileage oil you have had success with in this regard? Leaks/burning oil slowing down or coming to a complete halt. A lot of the maxlife love I see in searches is from 2010-2013 posts. Seems like they changed their add pack towards the tail end of then. Mobil 1 and Pennzoil HM I keep hearing good things about in this regard. I have noticed some improvement on oil burning/loss of oil but still seeing drips with GTX HM 10w30. Thinking of going up to 10w40 or giving something else a try. I've ran GTX HM for about 4500-5000 miles. I've seen some people post about switching brands & having success. Some from maxlife to gtx hm or vice-versa. Guess every engine/seal is different. In the end I may just end up having it replaced but would like to give the HM oil more time.
