wow thats a lot of fuel.
how many shot gun noises and cooks does that include?
when i had my 4k, id get about 12-14l/100km's that was a max of 80kays on my L's so slower than granny driving! that was about 4000rpm on 80km's (4 speed and completely standard healthy 4k). revved well but was very thirsty
with 4ac, weber, electronic ignition, huge cam, exhaust, babying it on highway spec i can get around 7L/100km's. not only that but when i thrash it it uses 11/100km's.
also i use premium (95 ron) as it would ping on regular but is actually tuned (by screw driver and ear) to run best on 98 ron ethonal which i get rahter poor economy on, but more power and its cheaper which offsets it. on the ethonal blend id get probaly around 11-12L/100km's but id tend to want to give it a bit more as it run much better and has noticeably more pull.
