I'm proud to have finally joined the Engine Maintenance Mode club. This is a great day. It means I'm not using gas anymore and the Volt had to fire up the gas engine for a few minutes to keep things working and maintained.

For years I have seen posts by those complaining about EMM, but for me, it's a badge I wear proudly. All my Volt driving is within it's battery range, while my wife with the long commute now takes the Bolt EV.

I had been thinking of installing the 39K Ohm, 1/2 watt resistor into my air temp sensor to defeat ERDTT, but my wife talked me out of it. "Just let the car do what it wants to do, let it use some gas in the winter. It's a little bit of gas in the cold weather. It's fine."

Congrats

And yeah, I agree with your wife on ERDTT. Gasoline is extremely good at generating heat, and has an added bonus of charging the battery a tiny bit, so I don't mind using it for what it's good for.

Come to the dark side... Slay that ERDTT and be even more gas-free

P.s. if you were driving when ERDTT was needed but it hasn't finished by time you arrive at destination, put your foot down in park to kick it up to higher speed and finish faster. Otherwise it resets if you turn off before finishing and you have to do it all over again on next run.

In other words, you're officially kicked out of the "never seen an EMM/FMM club" which I'm destined (doomed) to be in forever.

Congrats! How long does that take to kick in? I always seem to manage to use a little gas every few weeks.

I was hoping to get whatever the warning is to add newer gas to the tank on my first tank of gas from the dealer, but I don't think I'm going to get there. I've had the car almost 4 months, and 4000 miles, but I'm down to about a gallon (plus the reserve after "E") of the dealership's full tank of gas that they provided with the car. Still, I'm getting almost 500 miles to the gallon so far, so I'm not complaining.

Congrats! Does it take about 6 months to kick in, assuming all the gas was put in at the same time?

EMM has nothing to do with the fuel age, it has everything to do with how long the engine has not fired up to keep the fluids flowing, gaskets sealed, parts lubed. It’s FMM (fuel maintenance mode) that burns off what is in your tank to force you to put in fresh fuel. You dont’ have to wait until you’ve drained the tank. Put in a gallon and it will average the old gas with the new for a new FMM date. Put in 2 gallons on top of your 1 remaining gallon, and FMM will be pushed out longer. Put in 3 gallons, and .....

Congratulations!

I wish I could hit EMM, but the Volt is just so nice to drive I end up taking it on long trips too often.😀

Now the important question...Did you sit in the driveway while the EMM ran, then shut off the car and restart it so all your driving would be on the battery ala Plug1in?...

That would be forum member ari_c

My car's about due for an EMM, too. According to OnStar, it's been 30 days since it used any gas and I know it's been longer than that.

 

[wordptom]

An EMM! Way to go! Six weeks with no gas!

Your next goal is to run out of gas in the next month or two or three and then put in all fresh gas, thereby arranging the timing for your first FMM to occur during the colder months a year from now. I learned during my second FMM that one feels less guilty about using gas by switching to Mountain Mode (in a 2011/2012 Volt) to heat the cabin when the weather is cold and one is nearing the time for an FMM... and once the FMM starts, it’s a lot warmer in the cabin and the defroster tends to remain turned on longer to help consume the remaining gas...

I have achieved 76 MPGcs during the EMM! So what was your best score? I drove around the neighborhood at 24 mph for 15 minutes after I agreed to running the EMM.

The worst one that I got, just for the kicks, was driving in the freeway at 65 mph, and then clicking yes to running the EMM. I got like 45 MPG cs and used up 0.15 gallons of gas instead of 0.03

haha, no. I don't play those games. I just drive the Volt like a car.

 

[FISTA]

Had no idea EMM is a thing but somehow I achieved it on 3 months of owning the car... I love being part of this forum and community!

Just take a 6 week vacation. The Maldives are fantastic this time of year!

I drive about 3,000 EV miles a month and the EMM always comes on even before the month is over.

It shouldn't. It's supposed be 6 weeks of no engine use.
