It's like people buying the lowest grade gasoline to "save money"! Think about this if you saw 12 cents on the ground and it's under a shelf at a store, you wouldn't break your neck to get it. Yet , people will waste countless time and driving ( burning more gas) to save 2 cents on a gallon. Which in today's world I wouldn't want anything "low grade" cause you just never know how crappy they could make something now days and to buy the lowest grade is just dumb as well you get WAY better gas mileage on 93 octane! This goes for everything in life you get what you pay for and something is only as good as what's inside it or what you put inside it.
