5.7L engine oil temp over 220 ?

[RingSteel]

2017 1500 5.7L 4x4, 2000 miles on odo, I've seen the oil temp reading over 220 degrees several times on the freeway. It's still new, and I haven't driven it hard yet.
Is this the regular oil temp for the 5.7L, or is it high?

Perfectly normal for my 2016 5.7 here in Mesa AZ, even in the winter....

Mine used to sit at 224 till I removed the active shutters. Coolant temp would sit at 216 and trans was around 204

I wouldn't worry about it too much right now, with 2000 miles on it I'm assuming you still have the factory oil in it which at best is a synthetic blend and you're engine is still tight. When you change oil go to full synthetic and as you're engine breaks in you're temps should come down a little. My oil temp usually tops out around 215 to 218 but you also have to realize that these temp guages aren't a perfect science some may read a little higher or lower than others.

220 might be a little high, if consistent under a light load. When my truck was in it's first 5000 miles or so and completely unaltered, my high way oil temps were in the 211 to 214 range. They did climb to 220-ish under hard acceleration. Coolant was around 206 and the transmission was around 188. Now that I've removed the shutter assembly and replaced the 203 degree T-stat with a 180 degree unit, my oil temps in the summer hovered between 199 and 204. After I added Lubegard at my last oil change, my oil temps have come down a bit more. Not pulling my enclosed cargo trailer, on the highway I have to work the truck to exceed 192 oil temp; pulling the trailer, oil temps sit near 199 and will crack 200 if I accelerate hard or fight a strong headwind. Running 0w-40 oil too, so Lubegard clearly is reducing some friction.

Mine used to run that high as well....until I changed our thermostat to a 180. Now truck runs 185 on the button. I also got rid of the clutch fan and installed the v6 efan. Nice upgrade. Unless you are towing and working the snot out of truck this is a gr8 mod.

 

[Nutshell]

Even if your towing the V6 e fan is a great mod. Had this on my 2011 with a 190 t-stat and a tuner. Lots of South Florida towing and never an issue.

So what weight oil and brand are you running while its hitting 220*

wow those temps seem on the high side my 2010 runs consistently under normal load. oil temp 180 trans temp around 185 and coolant rarely goes above 203. run 5/20 red line

 

[69GWC]

If your oil temps dont get above 212* your not going to burn off moisture in the oil.
mine runs from 210-220 pretty much all the time, RL and 5w30.

You want your oil temps higher than 212. That way it vaporizes water and pulls it out through crankcase ventalation system. If it stays too cool you could get sludge buildup. Water gets into oil as a by product of combustion so its there and need to be escorted out.

 

[novelmike]

Yes, what the last two posts said.

I was concerned about my oil getting up to 240. Then I did some research. Absolutely nothing wrong with it. Oil that stays at some of these temps, that some of these people have posted, will cause more problems than having oil reach 230 every single time you drive.
Engine builders say you want cool coolant temps and hot oil temps. And 205 oil temp is not considered hot!

 

[huntergreen]

Agree, there is a point that running your oil too cool causes issues.

Little fun fact for you guys,your 212 boiling point is at sea level,the higher you go up in altitude the lower the boiling point. Same principle as your rad cap operates under.You don't need 212 to boil off the contaminates unless you're at sea level,and if you're under sea level,you'll need higher then 212 to get to waters boiling point

 

[Hipps2000]

Also coolant temps and oil temps are 2 differ things. On a long drive my coolant temp reads 185 but my oil temps are often higher, sometimes 200 or more. I will moinitor it to see how hot I can get oil when pushin the truck. It’s been so dam cold out lately.

True. It's due to air pressure. Thats why coolant systems are run at about 17 psi. Also water boils at room temp in a vacuum which is why you pull a vacuum on AC systems after replacing a component and before recharging with freon, to remove moisture. It also has something to due with why meatballs don't bounce, I think......

 

[RLJ10X]

Is there a reason to lower the engine temp, other than you don't like the number on the dash display?

I don't know anything, but there were a whole team of professional engineers that designed the entire drive train to work as a system.

If you decide to cool things down, I'd keep a close eye out for engine sludge. Pretty sure engine sludge build up is part of the reason why Dodge went to higher temps.

I'm pretty much exactly the same. Redline 5w30 as well.

The boiling point of water under pressure is higher than 212°. Under a vacuum it is lower e.g. water under pressure could boil at 260°, water under vacuum could boil at 140°.
