honestly speaking i don't have exact idea of deluxe's fuel average
as i never did as many as patrol average tests as i did on my pridor 100
but i did couple of tests once it gave me 38km/lt with double
and i had checked my friends deluxe it had given us 48km/lt with single at speed 40-50km/h
exactly same results were given by my deluxe too at same speed 48km/lt
what owners say i think you can expect average between 39-42km/lt but in slow speeds
if you drive it 80km/h i think average will fall by big margin it will give you 32km/lt
