Guys and gals, all engines will sludge if maintenance is neglected. The sludging is not the ultimate cause of 2.7l engine failures regardless of what all the internet hype is all about. Granted, it certainly doesn't help anything though. People always always always say that the sludge clogs up the 2.7's "small" oil passages and starve them of oil. In response to that, the oil passages to the crankshaft and connecting rod bearings (the parts that fail) are not small by any means. The only "small" passages are what go to the cylinder heads, and if those clogged up, that would IMPROVE oiling to the crankshaft and connecting rods. Nothing in the cylinder heads ever seem to fail on these things. However, that is beside the point. If you tear down one of these sludged engines, you will find that the oil passages are clear-- actually the only clean part of the engine. More importantly than changing the oil, the oil level must be maintained. Dirty oil is a lot better than no oil. There is a pattern here -- sludged engines = lack of oil maintenance = people who don't check their oil level regularly = low oil = high risk of bearing failure. Just do the maintenance. It is a smooth, quiet engine. If it starts making any kind of different noises and/or not running quite right, get it checked out right away. Do not put it off. You can just about consider all engine oils to be synthetic nowdays due to the amount of refinement going into them. Where do you draw the line at which an engine oil suddenly becomes "full" synthetic? I use 10w30 valvoline conventional. The oil light issue is more than likely the result of a bad oil pressure sending unit. It'll cost $50 for the dealer to replace it.
