I would respectfully disagree. I owned a 1985 Cavalier with the 2.0 four cylinder. The guy that bought it from me tore the engine down to rebuild just because. It had 190,000 miles on it, 35,000 from me...hard. I used regular oil in it, and the engine was sludge free, minus just a smidge on the rocker arms, and everything in the engine save one crank bearing mic'd to within regular tolerance for a rebuild...meaning the engine could have passed for new. There are circumstances when a synthetic would be useful. High temps, consistent high loads...like a race car, or a truck that pulls a heave load day in and day out. A daily driven car won't REALLY benefit from it.
