Hey guys I was just cruising and my oil temp was at 292° F and my oil change light came flashing on. I just did the oil just under 3,000 miles ago. Outside air temp was 30° F. Water temp was slightly above half on the gauge. Oil pressure was reading 3/4 on the gauge. I’m at 130,000 miles and have a 2010 5.7 1500. I’m thinking it’s a bed temp sensor. Any one have any ideas what the issue is? Thanks

Did you run codes, you need to address that because that wont last very long at all.

You may have already damaged heads, you can't go from 292 to 30f when you turn it off without problems. Heads and exhaust manifolds cool at different rates then the block, bad idea to have this happen.

Yeah, nevermind I didnt see the coolant temp part, likely a faulty reading, whew. No way could coolant only be 1/2 temp if the oil was 292, completely fake reading. You dont have an evic I guess, but you must have an evic for oil reading. What model truck, you cant get live coolant temps, my 2010 slt has that?
