honest consumption Qashqai 2.0 l, gas, gasoline, diesel ?

Hello qq-driver, can you honestly tell me what you are consuming? we are still superior or diesel or gasoline-gas-equipment. we have driven a diesel sample (automatic) and have needed exactly 7 l. therefore I am surprised that some write you need 8,2 l gasoline and 1 liter more with gas. if this is really true, gas would count. so, I count on your honesty with the details. thank you already ina
