Auto engine start/stop and effects on engine wear? #4383013

Hey guys, I recently leased a new 2017 Ford Escape Titanium with the 2.0L Ecoboost engine, twin-scroll turbo, 4WD, it's a lot of fun!

This car has a feature that my 2016 Fiesta ST didn't have and that is an auto start/stop function that shuts the engine off when stopped. Now this is a lease so I don't exactly care about long term concerns but if I decided to purchase it after my lease is up, should I be concerned about significant engine wear?

The engine oil cap indicates a 5W-30 but I'm sure it's the Motocraft synthetic blend so I'm betting that a nice 5W-30 synthetic or maybe something like Castrol Magnatec could be good to keep wear to a minimum if it's something to be concerned about.

Somewhat to my surprise, they seem to be fine with it, at least as far as the current age of vehicles so equipped go.

The latest news around here is that the Magnatec 5W-30 is now fully synthetic. It would also seem to be a good choice for these auto start-stop vehicles with the clinging ester Castrol puts in it.


Cannot see signatures any longer so it doesn’t matter.

How synthetic is it ? All this not synthetic etc about M1 and crickets when Shannow posted an interesting chart with Mobil 1 base fluids (what Amsoil said) and good comments on NOACK.
So, no other oil will be able to cling while one waits for the light to change green ? Let's don't let marketing types run with this stop/start thing wrt to motor oil ...
Start up (not so) wear has been horse here enough ...

I was under the impression that the stop/start feature could be turned off.
Check with the owner's manual.

There's no such thing as:
Too big of a battery,
Too large of a gas tank,
or too loud of a horn,
or too bright headlights.

It is synthetic enough for government work. Castrol Magnatec is a very good oil has evidenced by how well it has held up in GDI motors and turbo boosted motors as well. Truth be told I would bet that Castrol Magnatec is the best bang for your buck oil on the shelves at Wally World.

Don't know if engine start stop makes a difference when engine is already warm.

You wouldn't want to stop and start a totally cold engine a ton of times every day.

In one way it doesn't matter because pumps are volumetric and you have an ADBV so oil is always at the bearing, but...

In my experience the feature can be turned off, though usually the map prevents the feature from operating below a preset temp (probably thermostat temp?) to prevent an excess of cold starts. This feature saves unnecessary wear on bearings, but in turn places more strain on the battery, alternator and starter motor.

To deal with the extra wear on these components they are bigger/beefier/overbuilt compared to conventional equipment, so they last 'long enough' but cost more to replace when they fail.

Ultimately, it depends how many miles you do to determine if the fuel saving outweighs potential associated costs..

+1 Turning off the stop/start feature would be the first thing I did after putting on my seat belt and starting the engine.

+2 Fortunately, my wife's 2017 BMW with this feature defaults to off. It will never be turned on.

If you plan to potentially buy it, I would research how to permanently turn this "feature" off. The cars with the auto shut off have bigger starters, so by turning the shut off feature off, you will have a beefy starter that will most likely never fail. That alone would enough for me to turn it off.

No need to speculate about engine wear when we know for a fact other components suffer from repeated On/Off cycles.

Agreed....IMO it causes a lot of extra wear on not just engine parts but starters and electrical parts as well.

I think that it would be a good idea as long as it only was activated when the engine is warm, it' can't be good for the engine to be constantly shut off and started again in cold temps, also warm up i imagine would take much longer.
