ideal running oil temperature

[ee90adict]

guys i installed an oil cooler for my car so i guess im gonna ask what is the best running temperature on my 4efte engine before when there is no oil cooler i used to have 120degrees -150degrees maximum but when cruising its 95degrees but now when i installed an oil cooler the maximum temperature is 95degress and the cruising temperature is 75degrees is that ok?

Oil temps will differ depending on what grade of oil you use, what your climate is like and how you drive it, but somewhere around 90-105deg i believe

i see i use 10w-40w oil sir and here in the philippines it is really hot and tropical...

 

[4efteboost]

to be honest im not to sure what your temp should be in your very hot climate but looks about right

 

[ee90adict]

ok sir by the way do you use to run with oil cooler also?

It depends on your climate mate. You were seeing excessive oil temps before. Try swapping your oil to something like a 20w 50/ 20w60. You are most likely running the oil to thin with those temps and that grade, you will be losing a lot of oil pressure which will cause fatal engine damage.

Your temps seen fine now, 75 degress cruising is about right, going up when boosting as well

oh i see so 75 degrees is i guess the right temp for my engine yah it goes up when boosting but minimal only, your from what country adam? and how's the climate there?

 

[AdamB]

75 degrees is about right for cruising. I'm from England mate over here we use 10w40 for our climate where we will be lucky to see 25 degree air temp. I would assume thats probably your winter temperatures :haha:

can i ask wat oil cooler kits do you use also do you run a thermostat

 

[ee90adict]

You are right adam 25degrees here is winter its summer here air temp reaches up to 36 degrees


I just use a universal oil cooler sir i dont have a thermostat on my oilcooler but i do have oil temp and pressure sensors in my sandwich plate

can i ask wat oil cooler kits do you use also do you run a thermostat

Mocal, HKS and Greddy (Trust) all have built in thermostats which are needed for our climate, as without the oil would never get upto temperature and cold oil is just as bad as super hot oil.

i run a mocal oil cooler kit, with the thermo sandwich plate and a 13 row cooler..
brilliant bit of kit tbh.. as adam says, you require the thermostat to keep a decent temperature..

75 degress cruising is fine..
ideally no higher than 110 degrees C when you are hard driving, if goes higher you be in trouble..
