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?
Asking for a friend
Probably not enough to outweigh the extra cost. You could adjust it a bit leaner or advance the timing.
