Is using auto start stop worth it?

[AmosMoses]

I was perusing the tube's and came across this documentary from a master mechanic sharing his thoughts on the pros and cons of auto start stop in modern cars. I know it's been discussed a little bit here so I thought some of you might be interested:

LOL - another youtube master mechanic. Well, add this to the dozens of others.
The comments below it are absolutely entertaining (and all from idiots who wouldn't believe you if you said the sky was cloudy when it was raining)
But you'll keep trying. You can find stuff pointing either way - and you'll keep choosing that side.

By default, in suburban traffic, you have the thing stopping and restarting every minute or so, often for just a second or two, unless you deactivate it and then there go any benefits of this expensive complicated system. And with stick shift the timing can be such that sometimes it throws a warning about how to start the engine when it already started. Just what you need as you are turning left across traffic.

I wish they'd allow to reverse the logic. By default leave the engine always running for busy bumper-to-bumper start and stop traffic, unless you press the "I'll be here for a while" button for a train or a two-minute long traffic light, in which case it allows ESS this one time, then automatically defaults back to engine always running again without any more user input.

Right now you have to deactivate it on start up, activate when stopped for a while, then deactivate again once you get moving.

Typically I forget to deactivate it on start up, it triggers at some point, I let it sit until moving again, then turn it off from that point. This results in a "mere" 2x starter usage per trip. If nothing else, it's a verification that the batteries are not yet failing.

Recharging the the battery doesn’t come for free.

That video was filled with a bunch of nonsense statements, for sure.

Tazer Mini for the win. Remembers your last switch selection.

He's obsessed. His last thread on this was loosing steam. Looks to me like he's desperately looking to. Validate his opinions and hatred of something that has existed for FIFTY YEARS and is proven tech used by several other companies.
Once this thread loses steam or he finds another video, another will be started. There are dozens of threads on this going back 5 years in these forums. It's been discussed more than just a little.
I guess it feels good, he'll keep doing it or until 100% agree or validate his hate of it.

Everyone misses the full point of it. Emissions while idling and fuel use. Edmunds And others have absolutely proven the fuel savings....see his other threads on this.

You bought a Jeep for its amazing emissions control? That’s like wearing a mesh tank top to protect yourself from skin cancer.

Wow, another one who refuses to open the mind to the rest of the world.
I laugh when I see stuff like that because it's such a narrow view, leaving out everything else Jeep/FCA/Stellantis sells.
take a look around you - what else does Jeep or even Stellantis sell?
Ever heard of CAFE rules and regulations? Yeah, it's spread across the CORPORATE FLEET.

Yeah, it sort of does. Watch how a properly operating "intelligent charging system" works. When all things are operating as designed, the battery charges when you let off the gas, or are going downhill. Part of the programming monitors torque demand from the engine. When there's high demand, the charging system cuts back - heck, it can even disengage completely, and when there's low demand - coming to a stop, braking, going down hills, it ramps up charging.
In a sense, it operates like a hybrid system would

9and BTW - hybrids have been stopping and starting engines for decades - but this is something that is "new" to a few people and they just don't fully understand it, or it annoys them, and they hate it - sometimes "just because".

There was a time when cars had crank starters and then switched to electric and im sure people were saying “well this sucks”

Damn electronic ignition - I want to set MY OWN TIMING! I know better!
Damn those fuel injectors - they don't let me double my CFM and mess with the jets and metering rods. Engineers suck.

This was one of the worst ideas ever dreamed up. For any fuel savings that might be gained will be lost by repairs or replacement of starters, batteries, and other wearable parts. People that do a lot of stop and go city driving will be the first to indulge in handing over their wallet to repair shops. If the world is trying to reduce, reuse, recycle, this feature should be on Darwin's list. We have two vehicles with the auto start/stop and get annoyed when we forget to push the button to bypass it.
