In all honesty and jest aside, it is my firm belief that oils with prime quality base stock, be it mineral or synthetic, cannot be cheap. 27 bucks a gallon puts the oil in Walmart base quality in my book.
Viscosity index is not convincing.
The low flash point means the oil is diluted to improve premix ease, so you should use a bit more of it.
It is quite easy to surpass Jaso FC class requirements with modern oils. An oldfashioned quality mineral passes easily.
Base number is quite good.
To sum up:
Yes, the proof of the pudding is what counts here.
How well does it burn off, what about carbon formation at several mixes.
How much ring wear after 100 hours operation.
What mix ratios are permissible.
Will it keep the cylinder wall clean, or deposit anti-scuffing agents?
What about exhaust blocking?
What about muffler choking.
