    You'll have to get a (corded) electric lawn mower! :)

    From the look of thoee gas cans I think a push mower would take a long time to clear his lawn

    I have an electric push mower, a Greenworks 16". I'm happy to say I don't have enough room for a riding mower; if it were that big, I 'd let it out ti a spin farmer.

    Our Volt's my wife's commuter, so I haven't been following it too closely. The garage is on its own meter so it's mostly the Volt, plus the garage door motors and lights and iright now it's OK. The Volt still gets filled quite a bit because we typically drive a 105 mile round trip on Saturday and my wife drives around 50 miles on another day, mostly Interstate.

    My wife gets 4 weeks off in July though.

    I finally saw another Volt near us, black, Could be the Chevy dealer tech who has one, but I hope it's a new one.

    Yes, I have about 6 acres out of our 12 that I keep mowed fairly regularly. John Deere with a 56" deck and sometimes use the compact diesel and brush hog when I let it get too high). It would have to be a really long cord :).

    I took the Volt to work today and topped it off again today. When I started it to go home I got the Engine Maintenance Mode message. Another first.

    So Rick , what does that mean ? Are they telling you to run the engine more often ?

    Or just change the oil ?

    Uh oh. Lights make me understanding is that maintenance mode starts the engine in order to use up fuel and keep it from getting stale, varnished, etc.

    Great results though. Proof of concept - I've been saying for a long time that a more purely electric car with a range extender engine is the way to go and that standard hybrids got it wrong. Now if they made the range extender a diesel...integrate a few solar panels into the roof...

    There are two modes in my Energi, for stale gas (18 months old) and oil maintenance mode. Stale gas mode requires the engine to run till one gallon is left. I don't think that's Rick's problem now. Oil Maintenance Mode requires the engine to run to burn off contaminants in the crankcase oil through the PCV system. If you have too many cold starts without the engine running for very long, moisture and gas blow-by the rings into the crankcase. The computer records and counts these events and commands the engine to run at operating temperature till the contaminants are burned off by circulating them through the PCV system (about 20 - 30 miles). The computer then resets, and starts counting cold starts again.

    If I drive in EV all the time, I don't have many cold engine starts and avoid Oil Maintenance Mode. If I ever get to a point of to many cold starts, I can take a 30 mile trip in EV Later Mode to clean the oil, or change the oil and reset oil life to 100%. Since the oil can go 2 years or 20,000 miles between changes, a 30 mile trip should be less expensive to just clean the oil with the PCV system.

    There are two modes in the Volt that will run the engine (well 3 if you count engine assisted heating when it gets real cold): Engine Maintenance Mode, and Fuel Maintenance Mode.

    Engine Maintenance Mode (EMM) runs after about 6 weeks of no or very little engine operation. This is to keep the engine in good working order according to the manual. It will run for 5-10 minutes.

    Fuel Maintenance Mode is for burning off old gas.

    An interesting note: I was reading posts about EMM on I was wondering how some volt owners on could get 20,000 or more miles driven without using gas. The key was "miles driven". What they do is let EMM run when it comes up with the Volt parked, which keeps their "miles riven without gas" streak alive. On the plus side it does seem to use less gas if your parked for EMM.

    Gary, I doubt I'll ever see those modes on my Energi with my work trips. I did drive the Energi to work today and filled it up at the charging station before returning home. I ended up with 159.8mpg on the 58.6 mile trip. Only 9.8kWh used though since I still had 9 miles left when I got to work (didn't decide to charge until I was almost there or I would have used more battery on the way in). So, I could have done better.

    Not anywhere near your numbers, but a heck of a lot better then my original C-Max!
  10. And then their CS mpg is single digits:confused:

    Had to move the Volt this morning to get the dogs loaded in the C-Max Energi. Engine Maintenance Mode ran for about 5min and only .03 gal was used.
