is the mpg accurate

[genesisinatl]

I just got a new 3.8 genesis sedan premium package and on the 2nd day am averaging 34 miles per gallon on interstate when there was not much traffic (I reset just before I got on the highway and after driving 50 miles at 65 miles per hour). Then in downtown it was stop and go for 4 miles and it dropped down to 30 miles per gallon and stayed that way. I was pleasantly surprised but I am now beginning to suspect that this is not accurate. I will calculate the true miles per gallon when the tank empties. However I did drive another genesis 3.8 premium for 3 days and it was averaging 22 with 40% local 60% high way the first two days. I wanted to wait for the hybrid lexus es300 but couldnt wait for that long. I am glad that the genesis is giving me good mileage though.

I average a combined HWY STREET mileage of 25.9 with my 4.6 sedan. of course the exhaust and intake help open up restriction - i can get a few more mpg if i use premium......

The MPG on the dash is over by just under 2 MPG, I have measured it with fill up and mileage several times. I had two 2011 Sonatas they both were just about 2 MPG over true mileage.

I agree the mileage on the car is high by about 1-2 mpg. On a related note the speedo is LOW by about 2 mph.
