Start-Stop Technology on 2.0L Ecoboost

[Koolflyer]

Any thoughts out there on The start-stop technology as related to the turbocharger? I realize it's a gas saver and great for the Hybrid, but it would seem that constant engine restarts during stop and go city driving would cause additional stress on the turbos due to rapid changes in temperature which could increase Coking, and reducing pressure (at least momentarily) which in turn lead to brief oil starvation to the turbos. I've had other turbos (not Ford) that benefited from a one or two minute cool down after driving. Abruptly shutting off every time you come to a stop seems like a bad thing for turbocharged engines. Again, any thoughts would be appreciated.

I turn it off every time I get in. I think it does a lot more harm than good especially on turbocharged engines like these.

Having start/stop enabled on your EB makes every drive an “extreme conditions” drive.

My pre-drive routine includes disabling it.

The turbo has oil and coolant going to it. I've only idled the truck once to get it to cool off: when I was seriously hauling ass climbing a forest service road in 100-degree weather with the AC working.

I'm personally not worried about the EcoBoost reliability at all. The transmission, on the other hand...

Circulation virtually stops when engine stops.

There are 10 mile stretches in my area that have 20+ traffic lights. If you don’t time the lights, the stop & go would be brutal on the oil if engine turned off each stop!

When driving "normally", the turbo does not get hot enough to create any problems during stop/start operation. Of course this assumes proper maintenance. There are a variety of parameters that will defeat ASS if conditions are met, to prevent any unfavorable effects.

However, I always defeat it when starting my truck, because I find it mostly annoying, and am not concerned with saving a fractional amount of gas.

My understanding of the '25 EB is sequential multiport injection at lower rpm, gdi and turbo only at higher rpm.
Wrong?

Just get a run stop eliminator and be done with .

My battery is never fully charged enough for the feature to operate. If it did I would buy the device to turn it off. No way thousands of extra starts does not affect systems.

i`ll save my starter and keep oil flowing through the exhaust heated turbine bearings.
start stop eliminator installed.

Partially. The EB turbo is managed by torque demand, and is not rpm dependent.

It looks like the consensus is that it is indeed ass.

My pre-drive routine includes disabling it by pushing the start stop button in the dash

My understanding is that the coolant does not stop cirulating during an ASS stop. The mechanical pump stops but there is an electric pump that continues to circulate for the HVAC and to prevent overheating. Could be wrong but thats what I have read.
