importance of oil temprature

[MrNeonDriver]

Hi, had two ideas but with this one i had a discussion recently and maybe you could clear this up for us.

My take on oil was the cooler the better , ok not to cold off coarse but say 175°F is better then 195°F cause it would span the life of your engine and the same in transmission (On which the discussion started btw )
And the other said it doesn’t matter whether it be 175°F , 195°F ore 215°F as long as you regularly changes the oil anyway, it shouldn’t hurt the engine.

the other idea is that it would, ore would not be worth it , to keep a car till it’s an classic. 60 years ago it’s said buy a new one, this car is total.
Now these cars sell for triple the money of a new car not that’s the plan but hey who knows.

Engine oil needs to become hot enough on a regular basis to “boil off” accumulated moisture and certain other contaminants.

[MrNeonDriver]

True but then again, what is the ideal temprature. i couldn’t think 215°F ore hotter oil is really good for the engine, it would burn the additive in it . doesn’t it ?

This was the first result I found when I Googled “engine oil temperature”:

“A standard water cooled engine should operate with a cooling system temperature between 80°C and 90°C (176F and 194F). Considering that the oil operating temperature should be 10°C to 15°C (50F to 59F) above the coolant temperature, then the oil operating temperature should be within 90°C to 105°C (194F to 221F) but should not exceed 105°C/221F.”

I’m sure info from other sources will drift a few degrees either way, but won’t be far from those numbers. Remember, liquid water will vaporize below 100C/212F, so there’s no need to bring things up to the boiling point.

Thank you !
Yes i couldn’t let it go ,cause as you said it should boil of water etc. so i went on a search to.
Disclaiming but not condoning. :dry:
either way. i was not the technician in this discussion but here is some.

as you said , it should not exceed 220°F it would hurt the engine and the cooling system i guess .

anyhow. Thanks for your input .
Maybe Eric can explain why in a video why ?
but i am gonna take this info and restart that discussion 😉

Hey guys,

I am also interesting in this topic; engine oil temperature; my owners manual says that I should go to see the dealership if the engine oil temperature gets at 150 degrees Celsius.

I also talked with TOTAL, the oil producer that my car, a Peugeot, should work with, they said that it’s safe to have the oil temperature up to 120 or 130 degrees Celsius.

The problem that I’m having is that recently, my car would get up to 120 degrees Celsius and I don’t know why so I am interested in this discussion!
