That's exactly what I logged mine at today and my ambient temps are probably 28C cooler than yours.

 

Thanks for doing that, Steve. Seems FCA run them a bit cooler than “normal”.

 

When I was test driving mine, noted that the water temperature "needle" stuck below 210 the whole time. I'm used to the "needle" sitting at the middle of the gauge.

 

Same here, just below the 210 mark. Used to be analog gauges would hover around half sweep, needle in the middle, to indicate normal operation. If the needles were pointing up, all was well. Except the fuel gauge!!

Goaterguy: I see you are in Charlotte, NC. I'm in Mooresville. For a really fun ride check out Brushy Mountain Road heading toward Wilkesboro. Also check out the Yellow Deli on the way there for a quick sandwich and a nice sit down before the ride!!!

 

No wonder we're seeing fuel dilution in our oil analysis; the oil doesn't get hot enough to vaporize the fuel rapidly enough relative to the rate of dilution.

 

Are you suggesting these engines may be running too cool?

 

I'm guessing these motors need to be run this cool to stave off knock. It's a compromise.

 

I suppose that the 80C (176F) value comes from the OBDII? Otherwise, the gauge on the cluster shows approximately 205F (96F), which is not a low temperature. My C300 Mercedes only gets to 85C when warm.

Nevertheless, something could be wrong with the OP's car, though. He doesn't reach 24 US MPG, when I average 32 MPG.

 

If I remember correctly, some early cars came with a lower temp thermostat that was being replaced by FCA. Does anyone recall this? I still prefer my car running cold and I'll change the oil every 3k miles. I have a Prima Edizione so its definitely one of the early production ones.

Are all the cars here running cold 2017s?
