I have about 2000 miles on my Scion IQ.
The car has yet to get over 29 mpg.
My last tank ran 27.5 mpg and the low fuel light started flashing at 175 miles on the tank of gas.
My IQ is running almost 25% less milage than the stated 36/37 on the window sticker.
I am 65 years old and drive slow with no Jackrabbit starts.
When I contacted my dealer, Billion Motors, in Sioux Falls, S.D. the service manager was defensive and indifferent.
I purchased the car because I expected good milage and now feel like a fool for having a small car that gets substandard milage.
I love everything about the car except the poor milage performance of 27.7 mpg when I should be getting around 36 mpg.
Legislation is needed protecting consumers from over stated milage ratings.
Since I posted my negative comments about the gas mileage for my Scion IQ I have discovered that the Governor of South Dakota has allowed big oil companies to sell 85 octane gas.
That 85 octane gas is being sold in 87 octane pumps and kills the mileage for the Scion IQ's four cylinder engine.
I changed to 89 octane gas with a 10% ethanol blend and my mileage jumped to a respectable 35 mpg.
If you own a car with a 4 cylinder engine beware of cheap low octane gas.
The oil companies are wanting to sell 81.5 octane gas in South Dakota or they may refuse to sell South Dakota Rapid City stations gas at all.
This would reduce our in state gas supply by 70%.
Big Oil strikes again!
An update to my review.
In my last tank of gas, following the tank that ran 27.7 mpg, the mpg dropped to a new low 24.9 mpg.
The car is now with the dealer where they are checking to find out if there is some problem with the car.
So far I love the car, hate the mileage.
