What's the problem? I don't see one. It isn't new technology. A couple of people here have reported greater gas mileage using it but I expect that is very driver/traffic specific. I leave mine on....I have control over it with my foot. If I'm coming to a stop and it appears I will immediately be on my way again I don't press down hard enough on the pedal to engage it. If the light just turned red, traffic is heavy and I won't be moving for a minute or so....I press the pedal a little harder to kill the engine. Startup is smooth and instant. What's not to like.

And you can disable it for each use with the button.

It dosent bother me as much as it raises concerns for the turbo's. Old school mentality tells me that the turbo's need to stay cool and lubricated to ensure a long life. Starting and stopping them just seems "wrong" in my head.

Meh, they wouldn't put it in on there if it would do major damage. Besides, unless you are planning on keeping it forever...

I wish I had it on my 3.5EB!

Correct me if I'm wrong but I believe Ford engineers have you covered there...oil continues to be pumped through the turbo bearings for a period of time after the engine shuts down regardless of stop/start or ignition switch. I don't remember exactly how...electric pump??? M1911

I'm pretty sure I read it somewhere. I know my salesman told me the bearings were cooled after shut down. Whoever made this point has a valid one....turbos run extremely hot and fast....oil can burn if the turbo doesn't have a chance to cool a bit. My most recent car was a heavily modified STI and while the turbo (forced performance) had oil line lubrication there was nothing to keep the oil moving after a fast auto x or track run if the engine was shut off. The solution, keep the engine running for a bit before shutting it down. The turbo locations on the 2.7 and 3.5 are excellent, short pipe right from the cylinders where the gas is still very hot and fully expanded. Fortunately, it appears Ford sorted this one out. At least we will see. Coming from a 5.4 l engine, I hope they have corrected spark plug removal and replacement also. M1911
