What grade of fuel do you use for 3.3t K900?
I had a 2017 Genesis G90 and only used regular 87 octane gas and never had a problem which is the same engine as the 2020 K900. The owner's manual for my 2020 K900 seems to indicate to use a higher grade of fuel. Is it ok to use 87 or should I use 91 or 93 octane? By the way I love the K900 as it has a more luxurious interior than the G90 and much better technology.
