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?
OP is asking about mid grade and I think most new cars don’t specify it, only regular or premium. I think some imports from the early 2000s may have required 89 but I have never seen it irl
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.
