My apologies if this is in another thread, but I couldn't find a cut-and-dry answer after searching for a while... With an automatic transmission, is it beneficial to your FE to shut the car off at a red light and then restart it when the light turns green? I understand that there will be greatly increased starter wear, but remanufactured replacement starters only cost $110 for my car, so if the savings in gas over that time would be more than $110 (about 44 gallons of gas as of today's prices of ~$2.50/gal), then it would be worth it.
And if it is worth it, what is the correct procedure for doing this with an automatic? I heard you have to shift into neutral, stop, turn the car off, turn it back on, then shift to drive and wait for the transmission to re-engage before letting off the brake / stepping on the gas. Am I correct here?
