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?
The Volkswagen GTI VR6 that I drove had a minimum octane rating requirement that was met by mid-grade gasoline.
A lot of older turbo cars had the same thing, basically minimum to keep the engine working right and in a range the computer can adjust to.
