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?
Even if they don't specify it, they often want it anyways. Most NA BMWs call for premium but will run midgrade, almost every Volvo calls for midgrade, Mazdas get a noticable improvement in performance from midgrade but only call for regular, etc.
