"seems" is a key word there. are you being confrontational, naive, or just plain uninformed?

HC touched on a few of my points, but this one baffles me..."Synthetic oil is a good choice if you have a high performance engine or if you live in an extremely cold climate, otherwise it provides no benefit (but no harm either)."

really? what about extremely warm climates? what about the occasional collant issues(busted hose, water pump failure, etc.)? what about the benefit of "extra" extended change interval, since he advocates extending conventional oil changes.

oil analysis...hmm, expensive, and based on a very small portion. i'll pass. he also recommends OE filters, then claims quality aftermarket is alright. make up my mind.

so, i'll continue to use synthetics, saving more money(and time), being more green, and getting better lube than conventional users...PERIOD

that's based on research(both intellectual and hands on) as well as my own experiences and observations.
