Does 5.0 coyote performance improve with octane?

[Junkyard Dog]

The dashboard video for the Steeda Mustang has oil temperature going from 190 something to 230 during a quarter mile pass:

Thats great. But oil needs to be above boiling to burn off condensation. Temps in the 220f range are normal. Not sure why you are obsessing over this.

This quite simply is not true.

Examine your own premise carefully before using it to construct your argument. A false premise frequently leads to a false conclusion.

Is it true that oil temperature must rise above 100° Celsius / 212° Fahrenheit, "above boiling" (here I assume you mean the temperature at which water boils, not the boiling temperature of the oil, which is much higher, well over 500° Fahrenheit), in order "to burn off condensation," by which I assume you mean to remove water from the oil? ANSWER - No. But do not take my word for it. Research it.

I used to run my cars in high school with no thermostat. I was young and ignorant. I thought the temperature gauge was broken, and, who cares, it was like 100° outside, right? Wrong. There was all kinds of condensation in the oil, which I did not recognize as such. I thought my oil was bad (and, in a way, it was). When I added a thermostat, I discovered that my temperature gauge did work. And the oil was no longer "bad," or in other words, the condensation was gone. The engine never ran over 212, though. My Yukon had a thermostat that opened at like 205° and also had no condensation. That engine gauge never budged over 205. Come to think of it, I owned two of those (a 4.8 and the Denali version with a 6.0) and neither one ever budged over 205.

Temps in the 220f range are normal. Not sure why you are obsessing over this.

It may be "normal" for your car. I accept that. It is obviously not "normal" for my car, which is unmodified from the way Ford engineers designed it. The pictures above show what is normal in my car in 4 different outside ambient temperatures when driving normally.

Obsessing? What an odd thing to say. I noticed the car in the video was at 228° on a 47 degree day when cruising slowly. I thought it odd, as my car is nothing like that. Others shared their experience. I shared mine. I shared photos.

I thought perhaps it was useful information for others reading.

I did not imagine I was bothering anybody with my "obsession." If that is true, I will carefully restrain myself in the future from being "obsessive" by sharing such information.

I thought others could find this information useful, especially given the cooling items on a handling package Dark Horse.

By the way, at the risk of oversharing my obsession more and driving you all nuts, a full throttle blast to illegal speed from a standing start brought oil temperature over 200°, barely, for a little bit of time.

Of course I didn't mean the oils boiling temperature. Lol.

But im not going to continue this any more because you seem to be taking the convo personally and misunderstanding my statements.

Have a great day and enjoy your car.

I did not think you did. I was being a smart aleck.

Interesting temperature range here

(from a GM paper about their OLM)

I'm not sure what you're saying here. Did you have an oil temp gauge in that car, or any other way of reading oil temp?
When that car was running at normal temps again, surely the oil would have been hotter too , probably over 212F and evaporating water and volatile contaminants?

Many OEM gauges back in the day were made to show normal without the actual temp. This would keep drivers from wigging out. One only would get concerned if it climbed out of normal.

And now we have people questions every gauge reading known to man...bring back the dummy gauges!

They were and are called "idiot lights". I'd rather have a guage to know what's really going on but then I have an education and am not an idiot. A lot of interesting things have come out of Detroit and it will continue to be that way. One of them is a car named "Mustangs" that a lot of people buy then turn around and go on a car forum and criticize the car they just bought along with the car maker, being Ford. The buying transaction was totally voluntary too!
