Not sure if you're planning to use the oil in a motorcycle or car, but: Yamalube has a really long warranty - longer than any motorcycle - but for their "dino" oils, change intervals are frequent, measured in hours; synthetics can run longer. Not really news, I know. Yamalube runs $8.99/quart for their cheapest 10W40. Not a bargain. For whatever it's worth, the fuel filters on cars are bigger than most MC oil filters, but then of course they carry less oil. Maybe there's some relationship between filtering & change intervals.
Obviously some MC oils have to work with wet clutches, so I'd guess their additive packages differ from automotive/truck oils. I'd guess that's the difference with V-twin oils, which probably also need to cushion better, judging by their heavier viscosity.
