Ion 2 Terrible Gss Mileage

[ion2]

I have owned my Ion 2 for a year and have 10,000 miles on it. For the last 6 months the mileage has steadily deteriorated to the point now where I am getting only 15MPG ! The local Saturn service dept. cannot seem to come up with a fix. All the sensors say eveything is fine. Any suggestions ? In most other respects the car runs fine but I bought it,in part, to save on gas.

Have you, or the service dept. pulled out the spark plugs? Does the car run any different the last 6 months, orther then lower MPG?

I've seen this happen with the pressure in the fuel tank not being up to snuff. There's a canister valve that controls fuel pressure, and it may be having a problem. This won't necessarily show up on a computer, so you might ask them to check it.

I was told to burn 87 octane always,this past fill up I put in a can of injection cleaner,seems to be idling smoother,I have 13K on it.It's been a fairly brutal winter here in n.e. ohio,the heater was gasping on those single digit temp mornings. last 6 months the mileage has steadily deteriorated to the point now where I am getting only 15MPG !
