That is my take with oil. If you use what the manufacturer recommends as a minimum quality point, I believe all will be well. If you choose to spend more to protect your "baby", whether it be an ATV, motorcycle, or car, that is up to the individual. While I do believe that some oils are better than others, I do not believe that it is necessary to use them. Realistically, how often does anybody actually keep a machine through it's entire useful life so that they will see the benefit of extended service life that they pay extra for using "better" oil?Not saying they're not both a great oil, they are both VERY capable of protecting the engines they are dumped in, these tests just boil down to "over the top" hype and a big E-dick contest on the internet. Shit, I've seen bearings guys have posted out of their mountain motors (700-1000cid BBC's) running wal mart oil, and internals looked just fine, though I cant remember which manufacturer relabels for wally world.
