    Hi Gary,

    I want to thank you for such informative posts and for being such an active member of the Green Hybrid community. Your posts recently helped me understand what was happening when my Marinier Hybrid stopped while running on the highway (very scary). Turns out it was the MECS pump which has now been replaced.

    My Mariner has approximately 68,000 miles on it. When I first got the car it was not uncommon for me to get about 28 MPG in the city and 30+ on the highway. Absolutely loved driving it.

    Over the last couple of years my MPG has slumped to the point where I'm now getting 20 MPG in the city and 22 on the highway. I perform regular maintenance on the vehicle and am baffled as to what the problem could be.

    Recently the MECS pump failed and I had it replaced at the local Lincoln dealer here in Savannah. When I dropped it off I explained my MPG problem and asked that they provide some insight after looking at the car. They fixed the pump and said that all systems are running correctly. Basically, they had nothing new to offer and frankly didn't seem concerned about my problems at all.

    I should point out that I have been told that my battery is weak and will need to be replaced sometime in the coming months. That said, I do not see the connection between MPG and the battery, so I have not considered this a contributing factor.

    She's back in the shop today getting another new fuel filter which may help a bit, though I don't think it will account for 8 or so MPG.

    Any information on what I can do to try to improve my MPG would be appreciated.

    Thanks so much.

    John
