Re: 2006 fuel reading low
It all depends on how you drove those 8 miles....If it was stop and go traffic then your AVG MPG is going to plummet thus reducing your range significantly...I never pay too much attention to the INST MPG, Range, AVG MPG, etc., they all vary so much since there are so many variables that can impact their read outs...
My 06 sts will read185 miles till empty and i will go 8 miles and it will say 100 miles till empty??????
I apologize that your STS is indicating you the wrong mileage until the fuel tank is empty. Curtc is right, there are multiple factors that can influence MPG. If you are concerned about this issue and would like to take it into a dealership for diagnosis, I would be more than happy to assist you in working with them. Please send me a private message with your name, contact info, VIN, mileage, and dealership you would like to be in contact with so I can reach out to them. Thank you very much for your time.
