POLL: How Do You Really Feel About the Start/Stop System?

What does that gauge cluster show? Miles driven and gallons saved? Can you explain please?

This is not an OB, is it?

So the picture is of my Auto Stop/Start gauge from my 2019 Forester Premium Pkg 15 option if it makes a difference.

It shows that during the “B Trip” that I plan to keep for Lifetime data, which has been a touch over 5,700 miles, the auto stop/start has been active for about 13.5 hours of idling, which means that it turned off the engine for 13.5 hours that would otherwise have been idling. It also saved me about 6.25 liters of fuel. For me, it’s not about the ~20 it saved me at the pump, but more about the fact that I didn’t just put 13.5 hours of emissions into the air. This is also the “drop in a bucket, but together we are an ocean” mentality, whereas if everyone saves 13 hours of idle emissions over 6 months, there is a greater effect on the environment. The same way people are critical of downsizing from V8 to V6, and again now from V6 to I4/H4 and turbo 4 cylinders.

I remember having a 1990 Jeep Wrangler with an I6 that would get me about 10 mpg highway, let alone city miles.

I was “used to” Auto Stop/Start in about a week of driving, and now it’s second nature. I can manipulate the force I apply to the brakes to not activate the system when I know it’s a short stop, like at a stop sign or in a momentary bumper-to-bumper traffic scenario to avoid an extra duty cycle.

In real life driving, after doing about 2 tanks of fuel with the system disabled, I noticed my mpg from the tank increase from the 20-21 mpg range to closer to 25 mpg. Again, I drive mostly in the city, so this means I end up having the system activated more than a highway driver. So I happily welcome ~20% mpg gains.

Also, yes, I’ve heard that permanently disabling it by tricking the computer into thinking it’s towing something will work, however, there is speculation that this will also change how the vehicle dynamics work, such as active torque vectoring, because the computer still thinks you’re pulling something. Be careful, as you are playing with a feature that can cause unwanted consequences.
