quote: For example, if I bought a Prius and drove 3,000 miles a year, instead of being enviromental, I am being quite the reverse. I required significant pollution of the enviroment to create a fuel savings technology I am not taking advantage off... that's easy example. For this start and stop, I personally don't idle very much. In a typical day I may hit 2 red lights for a total ~90 seconds idling. Do I save enough fuel to justify the extra pollution of the the technology? That's a legitimate question I think...
quote: I can do my own start stop by turning off the engine with the - KEY! And if I know the stop will be long I do do this now.
quote: What if it's really cold - say zero. I want my heat on if cabin temps are not warm yet. Some red light stops go up to 2 minutes.
quote: Don't concern yourselves with the claimed MPG increase. Start-Stop technology does not display significant gains on the US fuel mileage test cycle.
quote: however I'm concerned with one fundamental issue which could cause premature engine wear. When I first started learning about cars many moons ago, I learned that 70% of engine wear happens at start-up and that once an engine is operating at its normal temperature, its rate of wear & tear is minimized during steady conditions (such as freeway/highway cruising). Furthermore, I learned that you don't really waste a lot of gas idling at stop unless you're idling for several minutes (and that you idle for maybe 15-20 seconds on an average stop light). Anyone have any thoughts on this?

quote: @ Boingo Twang - Relax there before you burst a blood vessel; I was honestly asking because you're correct, my archaic vehicle (by your standards) doesn't have a fuel monitoring device. I guess to rephrase my point/question, would you incur more/same/less engine wear & tear if you manually turned off and then manually started up your engine at every stop light?
