Letting the oil warm up

[HoosierDaddy]

All S550s have an oil temperature gauge (in the information display)

I think he was pointing that the cars don't have an oil temperature sensor. Sounds like its the same as my 2002 SVT where the oil temperature gauge displays a temperature the oil "should be" based on water temperature and other inputs. But it should be fairly accurate assuming the inputs it used were accurate. But not foolproof, for instance very low oil levels would cause the oil to be hotter than the system "calculated" oil temperature should be based on proper oil levels.

Yes, supposedly no oil temperature sensor. But, I have to imagine that if they developed an oil temperature gauge (no matter how they did it), that it's relatively accurate. Since I don't have a pressure gauge (even a "virtual" one), then I use the oil temperature gauge, and don't get on the engine until it's near the center of the green zone.

My take on this is you start your engine and within a few seconds everything on the engine internals is coated in oil. Cool, cold or very cold and thick, its coating the surfaces. Your protected. Give it the gas. I mean if cold temp oil was all that bad we would wear out our engines just getting through the driving winter. The big thing I notice about warm engine oil is mpgs are improving as the engine temp rises.

I just let the oil temp go from Low->Normal before revving it past 3000 RPM. That's usually a mile or two.

No ... oil pressure is dependent on both oil viscosity and engine RPM. High viscosity increased oil pressure. High engine RPM increased oil pressure.

Only temperature of the oil changes it's viscosity ... as temperature increases, the viscosity goes down.

Yes, sorry I should have said that you can only use the pressure check at idle.

I do the same with waiting for the LC to show up

So what am I missing...I have a 2015 PP GT and the LC doesn't show up on mine. Do you always have it turned on or something?

In regards to OP-Usually let the car run for about 45 seconds before driving. Then I watch the oil temp needle while driving and do my best to stay under 2500/3000rpm until it hits green. Even on cold single digit mornings lately here in Michigan it only takes a few miles at the most. Lucky for me, it's almost always green by the time I hit the on ramps going to and from work

In the Ecoboost engine,

Oil temperature lags coolant temperature by quite a bit when the engine is warming up, especially in winter.

When your oil is cold (around 40 degrees farenheit, or 5 degrees Celsius), it creates high oil pressure in the engine (especially if you use the factory-recommended 5w-30 viscosity oil. There are 0w-30 viscosity motor oils available here in the US, and I would imagine up in Canada as well!). I would not want to make the turbo boost until the oil temperature is "in the green". Turbo seals are known to be sensitive to high oil pressure, and I'm sure that laying on the accelerator before your oil is up to temp in the Ecoboost is not being kind to the seals in the turbo... not to mention that since the oil isn't up to temperature, you're also being hard on the turbocharger's bearings.

The performance package cars have an oil pressure gauge. In mine, I try to be very gentle on the throttle in the winter until the oil pressure drops off (this lets me know it is up to temp). You can also use the oil temperature gauge (as others have mentioned), but personally, I like having the trip computer and fuel economy info in my face most of the time, unless there's a problem with the vehicle ;)

You have a valid point there concerning pressures.

I start her up and wait for the 2 big oil pressure drops before I start driving but keep her under 2500rpm until she hits green on the temp. Same whether it's 45F or 95F. I usually hit green at the same stop light every morning and the light after that is a 0-80.

Does this really matter? I swear this is only for old cars. If anything you might do damage extremely long term but gunning it after cold start (years down line) but everyone I spoke to said new cars it really doesn't matter

I also keep a eye on the Trans Oil, until its over 60% then put it back to the mileage screen
And on the RS will only leave her run for a few minutes

No it doesn't really.. Your oil and fluids are doing their job no sooner than you get backed out the drive.. Now if your in extreme cold that's a different process lol

 

[S7N]

I turn the car on and do a burn out right out of the driveway just before 6am every morning.

Basically every question like this (warmups, oil temp, high revs when new, etc) that's asked on this forum can be summed up as "it will have no noticeable effect on engine life. ford engineers their vehicles with consideration of human nature."

Be mindful of oil temp for two things:
1) Don't rev the car high in the first moments from a cold start - oil does take some time to flow
2) If you are boosted, FBO-tuned, revving significantly higher than stock, wait till it's warmer to get on it

Driving the vehicle will warm the oil much faster than sitting there idling. Just give it a little bit of time before jumping on the throttle. It will thank you, and you will thank yourself later. Hot oil flows much faster, and flow is what is important to keeping your moving parts lubricated, not pressure per se. It is correctly stated that Ford engineers the engine to be able to take abuse like this and still live to 150k miles.
