Great cars, great engines. I have 3 of them on the road, planning to swap another into a Baja. I much prefer the VTD AWD that comes with the VDC models. It's a shame to have the nice premium car and engine in the LL Bean, and the crappy MPT AWD.
Only engine issues I've had are valve cover gaskets, oil cooler oring, coolant hoses (there are a few small ones between the water pump and oil cooler, they get oil contaminated and seep. Also metal lines in front of the oil pan and under the LH valve cover can rust through) and serpentine belt pullies (the bearings in these can seize with very little warning. Pull them off and give them a spin periodically. The bearing alone can be replaced on the factory pullies).
I use plain old green EG coolant and regular fuel.....occasionally if there's oxygenated premium for a decent price, I'll use that, but not very often.
