Engine shut off at stop lights…

Anyone done any real research on gas savings, engine damage or any other info?

 

Study no. However the repeated stopping and starting can do nothing positive in terms of adding to the engine longevity.

 

I know they make a device that you connect to your car that immediately disables the engine idle shut-off, but I haven’t checked if they make one for Toyota. I assume they do. I have a Honda Odyssey and idlestopper makes them, also autostopeliminator makes them, but it seems not for Toyota.

 

So my Highlander has auto stop. I used to have a Chevy Malibu with auto stop. The Malibu would auto stop no matter how you pushed the pedal. Sometimes it would auto stop before the car was stopped (why I don’t have it). Comparing the two- Toyota is miles ahead in this regard. In the Highlander, push the pedal down lightly and it doesn’t auto stop. Push it down harder and it will. Is the Tundra not like this? Not sure why you would need a device to cancel auto stop. Btw they are designed to take the extra wear and tear.

 

Found this video on how to permanently disable it on a 2022 Tundra. Dude is selling them via eBay so I’m not sure how legit they are, but at least its doable.

or just dont mash the brake pedal. if you push on the brake pedal just enough to hold your position SS wont ever engage.

and it you need SS to engage, just push harder. do that all the time in drive thru lines that take forever.

 

The Tunda's stop / start is better than other cars I have driven with that feature. Nodak67 is correct. If you dont mash the pedal the feature doesnt enable. I've driven mine now for about two months and had the SS feature do its thing maybe 5 times. Otherwise it doesn't activate at all. I dont feather my stops and certainly dont need to put my foot through the floor to get the truck to stop.

 

I just want a normal car without all the extra stuff I have to do to get it to work!



Everytime I go somewhere it feels like I’m preparing for takeoff.

 

So if the goal is to press the pedal lightly to avoid it why not just press the disable button at the beginning of your drive?

 

cause there are situations where shutting it off like 20-30 secs is viable instead of just idling. best idea is drive thru lines. stop and go maybe for you cali people on the 405.

 

I agree with you gas savings wise. However you have to wonder about the wear on starter and other engine parts. Probably nothing but I still would like to just avoid

 

ive been remote starting my 2014 4runner for 9 yrs with the door open shut off. still on the oem starter

 

Modern starters are designed for auto start/stop. Early versions of start/stop were crappy and wore them out fast, but that isn't really a concern anymore.

I can't point you to any direct studies about how much gas it saves, but its enough that its pretty much required on most new vehicles to improve the EPA ratings and meet fleet standards

 

I've tried the auto-stop on a F-150, Chrysler Pacifica, and now the Tundra, and the smoothness of the stopping/starting is what impresses me the most. I do turn it off every time I start the truck, but for what it does it's impressive.

 

How about wear on the battery?
Engine bearings?

I'm just stay the only benefit is fuel savings. I don't see any evidence that it can have any benefit other than the fuel savings.

Do whatever you wish. That's the great part. I'm glad they all give us the option to turn it off with a button.

 

Vehicle components have advanced a TON in the last several years. Additional wear on components due to auto-start/stop is negligible. Modern cars are designed and built with auto-start/stop in mind.

the benefit to the manufacturer is they get to "cheat" the EPA ratings systems and fleet fuel economy standards. The fuel savings benefit to the end user is an added bonus, but they're mostly doing it to meet regulations.

 

Exactly what I was getting at. Should be the same in all yotas then.

 

Uses hybrid (deep cycle-starting battery).

 

Being a 43+ year "metrologist" (science of measurement), I'd like to see some actual "imperical" data to support the negligible impact that start/stop has on starter components. Especially since vehicle components have advanced a "TON" in the last several years. Please post your findings. Thanks!
