Skip the first minute. I think stop/start wants a 20hp, water-cooled altermotor that fires the engine after the car has moved 60ft.

He starts out totally nonsense against stop start. Spreading completely outdated misinformation. Then does a complete about face after he is sure everyone who hates fuel efficiency and promotes a green living mindset has quit viewing, to debunk everything he said in the earlier half of the video to say that start/ stop doesn't have any draw backs. At that point it should be obvious to anyone that anytime the engine is off the car is using less fuel and emitting less waste.

All I can say is that I have the OEM starter motor in my 98 Civic. I key start probaly not less than 20 times per day or more (I have never counted). The started has 248,000 miles on it. The last 75,000 (during six years of daily driving) have been "start/stop." Mine is still going. I am sure there is wear, but it is hard for me to consider it economically significant since I have not seen failure (yet).

I thought auto stop start was a cheap trick to get +2mpg or more in city driving.

The starter in my current DD is 325,000 miles old.
I have buttons on the dash to stop/start the engine.
I use these while driving through town & at lights.
When I put the buttons on the dash, (in summer 2006) I also replaced the OEM battery cables with heavier ones. I used 0gauge (single aught for you old guys) wire & made the cables to my specs.
Negative goes directly to the starter mounting bolt @ the transmission, then a daisy chain ground through the engine bay. This will cause noise in your FM stereo so use aux input or Cd's or a ground isolator module.
Positive to the starter then OEM cable to the alternator.
I've had no issues with my starter and it spins noticeably faster than a car with OEM cables.
High amperage draw kills starters.

Then, one can easily come to a conclusion that start-stop is not the problem, and the power supply/management is the key to ensure a longer starter life. |

I thought the point of stop/start was the peace and quiet at the stop lights.

If +2MPG is a cheap trick, call me Rick Nielson!
