Default High Oil temps

i was cruising back from a local meet and noticed my oil temp gauge pegged at 150(the highest reading). the cluster temp was fine and car was running fine. was not doin any type of aggresive driving. I did notice the gauge go back to normal temp during some upshifts, but go back to 150 once in gear. this was around 8ish... just took my car out again and it warmed up fine and gauge was working fine.. go onto the highway and do some light cruising still fine.. Proceed to a on ramp, WOT the gauge goes back to 150. suggestions i'm thinkin theres a loose connection somewhere.. obtw this is the oem gauge pack. my buddy says that the sender goin bad on the oem's is a common problem, but i havent heard of this before.

sounds like celcius if that's the maximum value that his gauge shows....

Sounds like sender problem - my oil temp has never seen above 110, even during agressive driving.

I see about 190-200*F during normal driving....depending on the outside temp. In traffic...lots of stop and go about 90*F I will see at the most 210*F and will stay there until several miles of straight driving. My oil temp light comes on at 212 and I have NEVER seen that.

I suppose if I put it on a track I'd see upwards of 220*F.

FWIW, i just went and abused my car a bit....about 86*F outside....my oil temp at the most was 208. when i noticed coming down to idle, my vacuum was the HIGHEST it had ever been....26" solid.

I let the car idle for a few minutes in my driveway and the oil temp came down to just below 200*F


To the OP, i would guess you have a sending unit problem. Try out the DaddysSCP gauges...I have them and love them.

There is probably a sending unit problem. Quality aftermarket gauges ftw!
