Ok so when you go to the gas station there are three "grades" of gas (there's also diesel but that's not relevant here):
- Regular - this is what pretty much most people get.
- Plus - Why????
- Premium - for luxury/sports cars
So can someone explain what the hell the "plus" is for?
It's what I put in my lawnmower. It recommends 90 octane, but usually the mid-grade is 89, which seems to be close enough to work well.
