Oil Temps Close To 100c. This Ok?

[Andi]

Its been a bit hot lately and I've noticed my Oil temperature gauge is reading slightly higher then the normal 90c mark, its been very close to 100c if not at 100c these past couple days. Just wondering if this is ok for the GTT Skyline? Should I perhaps do a coolant flush and replace the coolant?

oil temp or coolant temp?

on our 86 corvette, oil and coolant temps get well over 100deg without any hassles. hell the fan doesn't even come on until the coolant reaches 110deg!

[Andi]

Oil temps, I just suggested a coolant change as I'm assuming with cooler water running through the engine the oil temps might drop down too.

No problem considering the water temps were around 90C on a mates GT-T from memory. What oil are you using?

[Andi]

Water temp seems to be normal, just abit under the half mark in the stock gauge.

In the oil temp gauge its about 100c. I'm using Mobil 1 Gold.

Don't worry about it. The stock water temp gauge shows nothing. I boiled over and it didn't even make it to the hot section.

My water temp on the track the other day was 109 and it didn't move from the middle.

100 for oil is fine. If it goes over that much then worry.

If your worried, stick an oil cooler on. But as abo said, 100 is ok, but don't let it go much higher.

My car runs about 95 in normal street conditions on hot days.

The other night (cool night) I took my car through the hills, giving it pretty hard for about 10minutes flat out, and the oil temp reached about 105 degrees.

I then drove it normally for 10mins and it stabilised back down to 95.

Is this okay?

I am running Motul 8100.

[Busky2k]

105C is nothing to worry about Nuffsaid.

[nuffsaid]

so when should i start worrying? at what temp on a hard thrash?

[Busky2k]

>120C and I'd be thinking about easing up because the oil viscosity will be thinning out. But if you are using the 5W50 then it should still be OK but still wouldn't venture over 130C under any circumstance.

[nuffsaid]

I believe I am running 5w40.

Cool thanks, under 120 it is!
