Those low weights are specified mostly for EPA fuel economy ratings. My Mustang recommends 5w-20 unless you are going to do a track session in which case it recommends 5w-50. Seems like an open admission that the lighter weight oil will not protect adequately under extreme conditions.Kinda the same, but different. . . . my kids's 2.4L Dodge Dart takes 0w-20. . . . my Jeep takes 5w-20. I've always felt that's too thin for our heat. But, both vehicles run fine, so what do I know?
Oil demands become much greater when a car is 'pushed'. Track days require different treatment, so I don't find that surprising. I have a 1.8T VW engine that's supposed to run 5W40, but most people are fine (and used oil analysis shows it to be fine) with running 5w30 which is more readily available. Reason: the "w40" part is really required when pushing the car, i.e. driving at over 170 km/h for greater than 15 minutes (that's 105 mph for some of you). The strains & stresses of track use are a different beastThose low weights are specified mostly for EPA fuel economy ratings.

I use the M-108A. None of the stores around here have the M-108 anymore, and fitment is the same.So. . . . M108. . . . or M108a? There has to be a difference. . . . the M108 is $3 more, although it looks the same.
Apex Cycle in Cambridge next to the Harley dealer. I had to pay by phone then go to the dealer and phone the parts desk from the parking lot. A fellow came out and put my stuff on a fold-up table then darted back inside.What shop was this? Only Yamaha store I know out that way was Oakville, but they closed.
Personally, I use Rotella T6 which runs about $50CAD plus tax for 5L. Yes, Americans, it's twice/three times the price here than down south. I have been using it in all of my bikes since pretty much day one with zero issues, will continue to use it.
I use OEM filters from Snow City, cost me about $20/filter.
