I would also support the gm v6. Generally with any modern engine, put an oil catch can on it at day 1 and change the oil every 5k miles and you won't have a problem. The issue comes from folks running oil north of 10k miles and never checking the level. Once the oil consumption starts, the lack of oil inspections kill the engine.

Too many people expect their vehicle to be an appliance.
