It's a great mpg since the power you have in it. I had count it to l/m which is liter/10km here in Europe 0.73l/m. If you where to drive it with the gas here 95 octane or even 98 octane I think you would have a little more mpg. My Audi S4 -92 5cyl turbo chip tuned to around 300hp was at 1.00l/m on 98 octane and 1.10l/m on 95 octane. And the Kia cee'd turbo diesel 128hp is about 0.5l/m.
