Guys with oil temp gauges , What are you running at when it's 90 - 95 degrees outside ?

I've been seeing oil temps at 220 , While the coolants at 202, Seems high , But i never really had the scan gauges set to oil temp , since the new engine was installed , And i was seeing lower oil temps versus coolant , until the ambient got into the 90's , Oil is 800 miles old , Mobile 1 . 3rd oil in the new engine 4900 miles or so on it . seems like it should be running cooler ?

Guru's please chime in , Is this an issue . ?

 

seems pretty high but maybe stander dont know off hand ill tell you tomorrow.

 

Thanks bro , It just seems to high to me .

 

I didnt get chance to drive the SS but I'll let you know soon.

 

Oil temps will for the most part follow water temps ...on a new eng they will be a bit higher untill everything gets mated together and settles down. 220 temps are ok....its when you reach flash point that u need to worry,,(400-500 deg).

 

And don't forget that the oil is also a "coolant" along with being a lubricant, so oil temps will as IgottaWoody pointed out, either mirror or slightly exceed the coolant temps.

Like an old aircraft mechanic explained to me years ago, "air cooled" engines should really be called "oil cooled" engines since the oil does the majority of heat removal.

 

At 96 degrees outside, coolant temps sitting 194 the oil temp is 204. So I say it's normal.

 

The rule of thumb I was taught is that oil temps should be about 5-10% higher than coolant temps on average.

So 194° + 5% = 203.7°....that's a happy engine!

 

Oil temps are very much dependent on TYPE OF DRIVING. So, EVERYONE will experience a slightly different value.

But for the most part, EVERY vehicle that I had that had oil and trans temp displays (some installed by me), yielded oil temps higher than engine temps.....sometimes as much as 25-30 degrees. That is ONE of the reasons I use synthetic oil. In the climate I reside in, it is not unusual to experience ambients exceeding 100 degrees for months at a time....nightime above 95 as well. Synthetic oil controlled tests, I believe, displayed continued protection above 350. And this is one of the reasons why I suggest to owners not to rely on ENGINE TEMP when concerns are expressed on condensation. It MAY take many, many miles of driving at 190 degree coolant temp to eliminate condensation.

NOTE: not wishing to turn this thread into an oil debate. Just expressing an example.

 

^ - exactly. Take Nascar for example..they run over 300 deg all day long ( with a storage tank and oil cooler) , also 8200-9200 rpms. Alot of it depends on system design and oil pan. Lowering your auto can affect temps as you take air away from the oil pan...some vehicles have water cooled oil coolers at the filter boss..works great as long as your cooling system is up to par. The bigger the load on the motor the higher the heat content.
