Why is my car burning gas so quickly?
Asked by MES77 Nov 13, 2020 at 12:26 PM about the 2011 Toyota Corolla LE
Question type: Maintenance & Repair
My 2011 Corolla is burning through gas at an alarming
rate, although my driving habits and daily miles haven't
changed. I have filled up 3 times in 5 days. I have always
maintained the recommended maintenance on my car. I
currently have 142, 072 miles, most of which are highway
miles. I'm not due for any maintenance for another 7,000
miles.

Do you have a locking gas cap?
Vacuum leak on the evap system can cause this
Thank you so much! How would I know if this is the issue? Is there something I can do to determine it, or would a mechanic have to diagnose the issue?
Visual inspection of the hoses, or make a smoke machine that runs off baby oil and plug it into the evap system
