Mine just says..."unleaded petrol".
However, I have read some reviews and the specs indicates that 91RON petrol is standard. Anyway I will use 98RON next fill up and notice the difference...price-wise and performance
Just wanna check with other RX400h hybrid owners whether they getting the mileage as claimed by Lexus ie 8.1l/100km?
I travel mainly on highways...cruising but still getting close to 9.5l/100km
