I'll pick safety everytime, whether on my bike or in my car. I want my engine on so that if I do not like the speed at which the car behind me is coming in, I have the option to go, to move, to drive forward, to get out of the way. Regardless of the wear on the starter or the potential battery drain. My safety comes first. But I also drive very defensively. I often get funny looks at intersections because I will leave whole car lengths in front of me so that I have space cushions. I've always operated under the assumption that 30 seconds of idling would use about the same amount of fuel as stop starting the engine, but I don't care if I'm waiting for a 2 minute light. Safety first.

It would be interesting to see how quickly the oil pressure drops when an engine is shut off. And if the fluctuation in oil pressure due to constant stop starts effects engine wear? I have always wondered why auto manufacturers never considered an electric oil pump to pressurize the system before starting an engine to reduce wear. Also if the alternator and starter are one unit in a stop/ start system does that double the possibility for failure in the system and also increase the expense?

I’m sure the start/stop system saves fuel over a conventional system. The loss of a/c at a stop light would be enough for me to not want the start/stop system. But, I’d like to see a cost comparison of fuel savings vs the cost of replacing that starter and the giant battery that system uses.

I’ve had a 2014 car with a start-stop system. Had to change the battery once, after about 7 years. The new AGM battery was roughly €120. I’ve never had issues with the starter after almost 10 years. So in my case, the car absolutely saved more fuel than the cost of a single new AGM battery in 10 years

It also depends on your battery power use to start the engine again. I've read that it takes about thirty seconds running your engine to recharge your battery after starting the engine, which I confirmed with my auto technician.

A built-in start stop system will take into account battery charge. So low charge and the engine keeps running. Cold engine is also taken into account, so when the oil is flowing nicely the system engages. AND also after maybe 90 seconds or 2 minutes, the enige will restart (i guess to keep oil flowing and prevent the engine to cool off too much). My Clio 2015's system works when stationary and when you shift out of gear ('neutral' but on a manual gearbox), so the automatic restarting can't be a danger. When you press the clutch to shift into gear, the engine restarts automatically, so you can't be in gear when the stop phase times out. So you have pretty much full control of when it works, or until the stop phase times out.

Did they account for the drain on the battery when starting the engine, which has to be replenished with an alternator running on fuel?

Very interesting! I was always skeptical about the actual benefits of these sorts of systems, as the cons of wear and tear seemed more tangible than the promise of fuel saving, so it's neat to get a real sense for how much fuel is really consumed or saved. With that said though, I still think this is a bandaid fix when it comes to the overall issue of car infrastructure being inherently less efficient and sustainable than public transit, when it comes to city commuting at least, which is where start-stop technology is targetted. I still think it has its niche, but car manufacturers and lawmakers really do need to be prioritizing sustainable transportation more. Just my stance on the matter

Public transportation is not automatically more efficient. It's only more efficient in very specific situations. If the train/bus is carrying a lot of passengers, then it is somewhat more efficient than a car. But if the train/bus has very few passengers, then it will be wildly inefficient compared to cars. I lived in Europe for years, and the trains/busses are often close to empty. The only time they get full is during the morning and evening rush hour. The rest of the day they're horribly inefficient because they're traveling the same routes on the same schedules, but only carrying a small handful of passengers. Cars have the benefit that they're only used when they are needed, they aren't running on a set schedule, so cars can often be more efficient.

@@SchemingGoldberg First off, I appreciate you for taking the time to consider how car infrastructure compares to public transit. I do implore you, however, to look into NotJustBikes here on KZread, particularly his Strong Towns series videos on the economics of cars and his anecdotal videos. The videos can be fairly clickbait-y, but I encourage you to give his arguments some proper consideration. In brief however: car dependency is, in actuality, expensive and unsustainable, inefficient and frustrating, and dangerous and stressful. Cars don't scale well leading to inevitable rush hour traffic, there's necessarily more expensive water and electricity infrastructure due to the lower density development, loss of life through poor safety and inherent human error, emissions and many other environmental concerns, increased social isolation, stress, noise and its impact on quality of life and productivity, etc etc etc Can public transit be done poorly? Absolutely. Can car transit be done well? Given the associated death rates and death tolls alone, absolutely not. When considering all the other drawbacks, you'd need to be misinformed and/or a morally ambiguous investor. With that said though, thank you for reading, and I do hope you can open your mind to the idea of doing away with car dependency.

Each day I make a trip to the local Starbucks and wait in line in an enclosed "tunnel" outside the store. Typically, my engine shuts down when I pull into the tunnel and when I reach the window. The baristas at the window have thanked me on multiple occasions for shutting off my engine, noting that they have to breathe exhaust fumes all day long. It's not a big thing but it's worth noting that in addition to reducing fuel consumption to some degree, start/stop technology makes the air a bit more breathable for everyone, some more than others.

Khargan: Since you would "never own a vehicle with a start/stop system" I suspect you've never even driven one. I have. Several, in fact, including the two I own. Besides, the notion that less than a half second hesitation in your car's movement would avoid or even mitigate the impact of a vehicle bearing down on you at speed is ridiculous, especially since you would not be able to judge whether the vehicle was approaching too quickly until it was nearly on you. Furthermore, even if you make such a judgement accurately, you're probably better off bracing for a rear end collision than plowing into a vehicle in front of you or running a red light where cross traffic could well result in a far worse collision. Finally, do you really think a manufacturer would install a dangerously sluggish start/stop system in a vehicle sold to the public? If you can document any such system, feel free to cite it. I thought not. Rear end collisions are, indeed, a problem. But they nearly always result from vehicles following too closely, a situation that has nothing to do with a start/stop system. And thankfully, such collisions have been reduced significantly since vehicles were required to add a third high mounted brake light.

About 30 years ago I heard of a study that said 40 s. But I am not sure if that was only in regard to fuel or also in regard to emissions (I suspect the fuel burnt during startup is burnt less optimally as well as the catalytic converter works less optimally). I am sure modern engines do better (ie, are more efficient when starting the engine). So I developed my personal 30 s rule with my now 20 year old car (ie, when my guess is that I’ll be stuck for at least 30 s, I shut the engine off). At times I tried to shut the engine off at every red light, but after twice relatively quickly ending up with a dead battery (the median time my car stays unused is probably 14 days, in particular in winter that doesn’t help with a weak battery), I reverted back to that 30 s rule.

@Fawexx No correlation whatsoever.

I knew about that 7 sec rule, that's what was written in my BMW manual (who reads it?). So every time I see red light, I check counter and if it's less than 10 sec, I keep engine running... however, auto start/stop feature kills car battery way waster :) So I hardly believe I save any money with this feature :)

Ive added Ignition security systems to my cars, and I can tell you there were days that my Crown Vic ran from dawn till dusk. Bought it with 4570 idle hours, sold it with close to 5000 in the couple years I owned it. Also not me but I owned a Interceptor Utility with 13800 total hours, and 8987 idle hours. Yes it was over 9000 when I sold it. Gotta say it was pretty nice in both hot and cold days to just keep it running the entire day.

Turn off your engine at the traffic light, floor it when it turns green. Saving fuel 😉

Just wait until your starter chews up all the teeth on your flywheel. Now you have to drop the transmission to replace it. Not to mention you might need a starter too. Now you have to spend a ton of money instead of just letting it run.

Counterintuitively, You're actually potentially right. An engine is usually most efficient at peak torque, which is pretty much peak power. So it takes less fuel to get from 0-60mph if you keep the engine at peak torque (assuming no wheel spin or clutch slip) than slowly accelerating. BUT assuming your journeys are the same distance, you spend longer at that higher speed, and for a non zero length cruise time, you use more fuel than if you had accelerated slowly, because you spend longer at a higher speed, and wind resistance gets higher with speed. BUT it turns out there is a most efficient cruise speed, and it's something like 45mph. Any slower or faster uses more fuel. So this only applies if the top speed is over 45mph... So accelerate up to

How Long are you leaving it off? A couple minutes off with a restart would make no difference even at -40 C/F temperature. Do you let your car idle overnight, so you don't have to start it in the morning?!? Get an engine block heater in that case!!

ABC123 basically a fancy word for assuming. If you really wanna go there, then every American is a drug addict. According to the National Survey on Drug Use and Health (NSDUH), 21.5 million American adults (aged 12 and older) battled a substance use disorder in 2014.

Awesome Video - I’ve been wanting to know how much fuel is consumed by my 1.5 liter Touata when its at Idle. And I got my answer from this video. .63 liter per hour🎉

This is a great idea in theory, but my mother-in-law's, Ford Fusion turns off at horrible times. I was doing a 3 point turn and it decided to stop. Because the engine was no longer on it was essentially in neutral (It's an Automatic (gross, I know)) and my gentle reverse turned into almost rolling back into the ditch. Some car do it way better though, but definitely not Ford.

Meanwhile my entire school spends their Friday nights at a local drive in burger joint with all their cars idling for hours at a time

@@bf3and4highlights83 The battery is being recharged when the engine is on, you know? Maybe turning the engine on and off multiple times in a few minutes doesn't really save money, but doing it when waiting at an occasional traffic light will very likely be benificial. Also why do you assume that starting an engine wears out any parts (apart from maybe battery, which isn't expensive)?

One issue I have in my 2013 model year Nissan Note (2nd gen) is that whilst the stop start usually turns the engine back on when the clutch is depressed the car sometimes won't always start with the clutch depressed and the car being put in gear. The solution is to put the car in neutral and try again. This can be dangerous during hill starts and frustrates people behind at stops as it appears that the car has stalled. I believe stop start are better for automatics of which this car had a CVT available. As for fuel used during idling the manual says it is only to be used if the car stops for 30 seconds or more, as this is written for all engine sizes and models this seems to be an estimate. The smallest engine is a 1.2 litre 3 cylinder gasoline with optional supercharger however there is a 1.5 litre diesel. This video does make me wonder if this differs for diesels since they require more fuel to start and also whether transmission type makes a difference since in Europe manuals are more prevalent.

I would love to see a video about this experiment but with diesel engines
