I have 2010 Pilot and it had about 2 gallons of regular gas remaining in the fuel tank.
On Friday last week, my wife added 2 gallons of gas out of a Gas Can that has been sitting in my garage more than 6 month.
On Sunday I drove it to Walmart (about 8 miles round trip) and the car drove just fine.
Yesterday (Monday), my wife drove the Pilot to do some errands (bank & grocery) and she called me saying the car did not sound normal.
When she brought it home, I turned on the engine and I see "Check Emission System" and "VTM-4" lights on and I can hear that engine sounds like a boat engine sitting idle (that is for the lack of better words. Should I record the sound and post it here?). I guess the engine sounded different and louder than normal.
Having said that, can adding old gasoline cause the problems that I am having?
If that is the case, can I drive to the gas station to fill up the gas tank?
