I have a 2006 that only made it to about 130,000 miles. Evidently for a two year period they made an engine that had internal chambers to flow oil that would plug...(at least that is what a couple different mechanics told me. I feel it was and now with a 'new to me' engine is under-powered for the size. I am pretty good at maintenance, although the oil changes were not done at 3,000 miles...more like 4,500 and I was told, this may have contributed to the issue.
