I just got the car. I found that it went through 8.1 gallons of gas at 195 miles, so around 22.5 mpg. It should be getting around 28 in town and 46 mpg on the freeway I believe. It has higher miles.
Has anyone had experience bad gas millage with the 1.6 gdi? Are there any common problems that decrease gas mileage with this model? I’m trying to troubleshoot cheap things first.
It has new spark plugs and I cleaned the map sensor. (It seems to idle a little high till it warms up after cleaning the map sensor).
I’m on a second treatment of Lucas injector cleaner.
I’m replacing the thermostat and coolant temp sensor in the morning.
What would you all check next?
How does one test the fuel pressure on direct injection engines? I’m not finding a lot online.
Thank’s for any advice.
