These discussions about the best oil always go around and around. We have owned our Pilot since new. Serviced at the recommended intervals with Honda spec products. Has 100k on it now and runs like a new car. If Honda or any manufacturer is too stupid or careless to spec poor quality lubricants, time to find a different brand of car. Any anecdotal evidence that one recommended brand (e.g., Mobil vs Valvoline) is better than another, when both products meet the relevant spec, based on a single or handful of experiences is not a sound basis upon which to make a judgment. Particularly with cars bought used, it is far more likely that driving style and maintenance history (or lack thereof) are the drivers of premature failure, noise in the gearbox, etc. This is one of the reasons that while I am a value shopper, I don't buy used cars. Very rare to find one where you are comfortable with the owne, or even known him or her, and the maintenance is documented. Rather than acknowledge this reality, people think there is magic in certain oils. Use a lubricant that meets the manufacturer spec and change it at the recommended interval. Everything else is all noise.
