I know a shop that sells these in vegas but I live in reno now so im SOL about that till I go there some time.
Also I'm looking at this viscosity range because aside from freakishly unpredictable weather in Reno Tahoe are around September- December, I will be snowboarding a lot in the winter and I unfortunately have to park my car out side where I live so i figure with my current set up and what not, this wide viscosity range can accommodate my needs. 
below is the link to the eneos site providing the information on their 0w-50 oil

0w50 isn't going to be any different than 0w30 in the winter. The 0w means both oils are the same when cold. Going with a 0w over a 5w isn't that big of a deal IMO, in the winter or even year around.
But 50 is the hot temp viscosity, which is pretty thick. If you're not really punishing the car (at the track for example) I'm not sure there's much benefit to running a 50 weight oil. I think most people do fine with a 30 weight... but you've got a pretty built motor, so you might benefit from the heavier oil.
For example, I was running 15w50 in my track car just to help protect the motor a little more when hitting crazy high temps at the track (270F). Unfortunately, that was back when I was still running Mobile 1 before we realized the formula had been changed. Even with the thicker oil I spun a rod bearing on that stuff... then again I also really ran the car too hot. So who knows if it was the oil that failed and caused the heat, or the heat that caused the oil to fail. Either way, no more M1 for me.
Currently I run RedLine 5w30 in my WRX track car, Royal Purple 10w30 in our outbacks, and Rotella T6 in the Miata, and Delo 400 in the Diesel truck. I may go with something a little lighter in the outbacks for the winter, like a 5w30 or 0w30, but so far I've been able to go long miles between oil changes without burning oil in the turbo outback, which is something of a miracle. I'm at about 8,500 miles since my last change (I know, I know, I need to change it!) and I'm down less than a quart. Not bad for a turbo Subaru, so I may stick with the heavier oil.
I don't know anything about Eneos oils, but I would assume that the weight selection logic will be similar.
