There is no fuel efficiency gained from the auto stop. It’s about emissions standards. In fact you may lose some fuel efficiency from the starting procedure.
Thanks for the insight. I’m confused though — aren’t emissions and fuel efficiency proportional (everything else being equal of course)? The emissions come from the combusting of fuel — If I’m combusting fuel, I’m releasing emissions. If I’m not combusting fuel, I’m not releasing emissions. They should go hand in hand, and roughly proportional to each other (I understand that starting takes more fuel than idling so of course there is some efficiency loss in re-starting over idling for some threshold time).

So, with A.S.S off: if I’m not moving but combusting fuel and going nowhere, by definition my fuel efficiency is decreasing (and my emissions are increasing). What I wonder is whether the financial and (production & shipping) energy costs of battery and starter wear outweigh the financial and energy savings from the A.S.S.

i don’t mind it, but i am curious if the wear on the battery and starter outweighs the fuel efficiency benefit. anyone have knowledge on the matter?
I just do not see the plus side of it. Wear and tear makes sense to me of the constant on and off. Should be an option when ordering IMO.

Looks nice. I had looked into a waterport which is basically the same thing, but a plastic container. The plastic housing is what deterred me from going that route. Looks like an aluminum tank?
Yes, aluminum … that’s why I passed on the waterport too! Very sturdy, came with everything needed to mount it, and quick disconnects for the included hose and sprayer. I bought a simple DC air pump to pressurize it after each use.

Good question. I have similar thoughts about weighing the advantages versus disadvantages but decided right away to shut mine off with a forscan setting because not only do I dislike the wear and tear but it annoys me to hit the gas and have my vehicle lung and die, then restart at a stoplight (which happened more often than not).

As far as fuel economy versus emissions the answer is no, they are not proportional. As emissions standards have gotten tougher fuel efficiency has gone down substantially in both gasoline and diesel engines. The additional processing that it takes to burn the carbon out of our emissions makes the engine much less efficient. If you strip all the emissions requirements off of an engine, you have much higher horsepower and better fuel efficiency from that same engine. That’s why you see so many people removing DEF systems and the like from diesel engines. It not only decreases horsepower and efficiency but also has more moving pieces and sensors to go wrong. However, I’ve not removed the DEF system from any of my diesels.

I’m not against emissions standards. I just think that often the benefits don’t outweigh the negatives and too often rules are put in place to make it look like we’re doing something and not because they actually make sense. Electric car mandates would be a great example of that.

Thanks for the detailed explanation! I agree that a lot of what we do is window dressing rather than functional. Curious to learn more about this — you’ve inspired me to look deeper, which (as a professor but also citizen) is one of the greatest things one can do. Rock on.

I bought Issue 01 today. I remember buying issue 1 of recoil magazine and giving it away to find out later it’s was worth a lot on eBay.

Is this anew magazine or a new bronco driver magazine

Made my first (tiny) upgrade: Used those FordPass points to get the Ford Bronco all weather mats to cover the carpet interior just in time for the winter snow and grime! Likely a few more small updates such as badging before I jump into the real modifications, but just excited to finally have it here!

I will dispute this claim.

ASS doesn’t engage at outside temperatures of 90° or more, so it rarely had ever shut off the engine in my Bronco for the first 4 months I owned it (I live a few miles from the sun). As soon as the morning temps cooled off enough, and the ASS started engaging at the 23 traffic lights I drive through on my daily commute, my gas mileage jumped up.

And a month later when the afternoon temps dropped enough for the ASS to start engaging on my way home, another jump in gas mileage.

I do understand that the ASS is way more annoying on the Auto tranny compared to my manual, so I don't mind all the people in Autos disabling it. But on the manual, if I know I am not stopping long (like stop signs), I just don't release the clutch and ASS doesn’t engage. And since the clutch starts the engine back up, and I have to hit the clutch to get going anyway, there is no more of a delay to get going than just the normal delay of having a vehicle that needs to be put into gear manually each time you stop. 😁😁
