What's the correct oil and temp. settings for the 5.7 Hemi??
I have a 300C AWD with a 5.7 Hemi.
Just had my oil changed and thought I would check my oil pressure digital read out. I notice the oil pressure when fully warmed up and sitting at an idle reads between 16 to 20lbs. Is that normal presure for the car at idle?
When at highway speed the oil pressure goes up to 45 to 50lbs.
Also the temp. gauge reads 210 degrees at normal highway speeds...seems high, but the idiot gauge on cluster just is always in the same position at the half way mark.
Your stock Tstat doesn't open fully until 203 F, so the coolant temperature looks completely normal. Oil temps will be above that by quite a bit, but I haven't paid attention to idle and rolling oil pressure. But I'm sure someone has...
See my photo gallery section. First name is... uh... Tim. I know... it's Goofy! LOL
In love with my first wife & first car ('68 Charger) ... still have the wife
but now there's the Heritage Edition and a Magnum SRT8!
Good to know my temp is running normal at 210 degree.....look forward to anyone's advice on the idle oil pressure issue?
You don't have an oil pressure "issue" - - your oil pressure is completely normal too; you only need 6 or 7 psi at idle to keep everything lubricated. As the engine RPM increases, so does the oil pump RPM - so you get more pressure when the engine is running faster, which is when you need it.
