tucson: I have a Hyundai Tucson V6 model, had it over a year and it runs amazing. No complaints about it all, but more a concern, I'm interested in what other owners are getting on a full tank of gas on there Tucsons? What is your total KM? Thanks|||What year model is your car? Depending on year model, they had a different final drive ratio due to excessive fuel usage. If you are getting 450km per tank around town - this is normal. On freeways it, of course, should be better. We have a close friend who gets 450 to 550km in city driving per tank and is very impressed.
