Guys,

I installed a DEFI oil temp guage, which measures in degrees C.

Anyone can tell me normal driving conditions oil temp reading? and when racing a bit on the road?

I am measuring 80-90 normal driving, and when hard driving (not racing yet) 100-105 Deg C, is this normal?

I am getting about the same temperatures as you. Although under harsh track conditions the temp rises to a little over 110C. Where is your temp sensor located?

 

Simple search return many results.

normal driving 100-105 c, at the track, it goes over 120 c

 

whats the safe limit for oil temp when racing? using 10w30

That depends if your running quality oil or not. But a good rule is to keep it below 120-125*C. I usually slow down if my oil temp goes over 125*C when racing.

I know people are running 140-150*C oil temp, but that's just insain IMO.

If you're slowing down while racing to keep the oil cool, you should be running an oil cooler, otherwise what's the point racing?

I run between 100-110C while racing but I have an oil cooler to maintain that temp.

I'm only a hobby weekend racer. I can't afford to rebuild my motor after every track event I attend.

Yeah, an oil cooler is definately a must.

yea thats what i pretty much thought.. is it safe to use a thermostat with the oil cooler so the oil can warm up when just starting the car etc? or would this not be a good idea because once the thermostat opens your getting cold oil in the mix thats sat in the cooler/lines..

 

i thought a stat is a must on most non track cars. I thought that this is because during normal street driving an oil cooler may not allow your car to get to operating temps, f course it depends on where you live too, the southern states is going to be different than up here in the great white north.

I heard a thermostat is not really necessary on a race car because the car is basically always going to have the thermostat open.

 

sorry yes mine is street driven with occasionally track.. what you said is what i thought also.. i think the thermo would do less harm than good in this situation however..but yea i was told by someone who works at honda an has a 10,000rpm b18cr that thermo wont be a good idea due to the mix of oil temps?

 

Thanks guys,

Its just to know if all is measuring ok.

I thought so, over 120 is peak, and just to be on safe side.

My oil temp sensor is at oil filter , where i have a oil adapter.
