Never thought about it or looked to see what it is. But I want to know what the oil temp should be at operating temp should be. I just put my. Mopar winter front on the truck. And was checking the coolant temp to see if there was any difference. with or without the cover. I just have never paid any attention in the past temp with the cover. Runs about 198. :confused:
 
5 miles into a 5% grade. Who really knows what the oil temp is! 32,500# combined.

I have a 2014 Laramie. I'd kill to have actual numbers for all temp's. It's a guessing game trying to figure out temp's when my gauges just have a white square that I assume being at the bottom is saying cool. In the middle I guess is normal and all the way to the top means She's ah gonna blow. No help from service dept. thinking about good after market ones and install on the dash. Can't put them on the window/door pillars due to grab handle being in the way. Coming home today, over mountain pass, snow storm, 29 degrees, flat stretch of road, oil temp gauge temp was two white square above (I guess) normal mark. Thinking that position was telling me oil temp was above normal which I think was to high for 50 MPH and below freezing air. Can't check other gauges while truck is moving. Has to be in Park to switch over to other gauges. Mountain grade is 6%. Not in 4 wheel, auto transmission/6 speed, in 5th gear. Temp stayed that way until I pulled into my shop. Only made one stop at a red light.
 
I installed a bypass oil filter. And the ECM doesn't factor that into it's temp calculations.

The oil volume/capacity is increased by more than a quart (1.5 quarts more approx) and having 2 filters means some of that heat is lost to the environment.

I can be sure that my oil is always running cooler than the fake gauge.
 
Assuming the fake gauge is close to accurate. What if the oil is hotter than the fake gauge.

Fake gauges just **** me off..

Agreed. Especially if using a winter front and other things that may not be detected by programming.

In the summer towing light in the mountains, I saw 212-215 on the fake oil temps.
I use Amsoil full synthetic because I know that withstands high temps.

I was going to install the same setup as you but couldn't be assured the gauge would be
accurate.

You aren't assured it is accurate now, so what's the difference.

Just like the fake oil pressure gauge. I am not even sure why Ram bothered with the programming.

I had this set up on a V6 Isuzu Amigo that went 150,000 miles and ran like new when I traded it in.

Just had a smaller bypass filter in the Amigo because it had half the oil capacity. I had concerns about oil pressure changing to the turbo. I didn't realize the oil pressure gauge was fake until after installing the bypass filter. So far no problems. The amsoil bypass filter forces oil through a pin hole that creates alot of back pressure to insure it does not starve any part of oil pressure.

Years ago I was a dealer for Amsoil. Prices kept going up and up. Finally lost to many accounts so I quit. I've got to find out what gauges
On my truck, if any, I can trust. Not very comfortable with the current system. Even my tire pressure readings can go up or down in a very short time spam. Also times when my Turbo boost gauge doesn't move when it should. My engine oil gauge, after I do an oil change,
informs me that it's time to change it again. The 'ol saying "drive 'um and enjoy 'um" doesn't seem applicable if ya blow an engine and look at the prices of a new one. ��

Bill the System won't blow you the Engine what ever the gauges show you - the system itself knows perfectly the real temperates and pressures.
The, I call them calmed down, gauges are just right to make customers happy to not run to their dealer every day when indicator is just slightly over the middle of the possible range of the gauge.

I've seen to many people going nuts with new engines that run at 100°C permanently for emissions instead of the old ones that run at 80°C.
Even 120°C is perfectly fine for a today Engine.

Actually it doesn't, in terms of oil. There isn't a sender on the engine even capable of telling the ECM the real oil pressure or temp.

It's the same as your 04.5 in terms of oil pressure. There is a 6 psi switch, that's it.

Really, on a 2015? Shocking.
How do that work with the emission system? European Truck have all those sensors. They even heat up the oil on purpose to come faster to working temperatur.
 
Okay, I will bite on this one.

1. Has anyone figured out how are they calculating oil temperature? In other words, what parameters are they watching to calculate temperature? Previous threads guessed it was coolant temps and load.
2. Is there a TDR Magazine article on this?

Thanks for the help.

From my trucking days with a dashboard covered with working gauges......

Engine oil and engine coolant ran almost the same temperature. Think about it, if your heat exchangers are doing their job that's exactly what should be happening.

Yes, I agree with you but we are "best guessing" it. I am wondering if anyone can confirm what other actual measurements and/or data is used to report it?

Pm your engine serial number or truck vin. I will see if the engine has an oil temperature sensor anywhere on it.
 
The temp should be close on the two, but with our small sump the oil temp has the potential to clime 25-50° above the coolant in a long hard pull. I have heard from from those who measure it that it doesn't go much above that.

As far as emissions, the emissions stuff doesn't care about oil temp or pressure so it really doesn't need to know

The last one I looked up didn't have one.
