Aux engine oil cooler

I drive a atx and you can pretty much call the mods i added to the engine mild. NGK plugs, msd 8mm wires and short ram intake, srt cat-back. I Installed a transmission fluid cooler about 4 years ago and so far the transmission is working like a charm. so now im considering adding a oil cooler for the engine.
would this be an over kill or a waste of time for my car? Imthinking there would be no benafit unless i had a turbo or high mod list.
need some feed back.

For your car it will be a waste of time and money, imo.

can someone give me a example of when it would be ok to run a aux engine oil cooler.

I would think that it would help when in a high performance N/A application or in a turbo application.

so if i did add a oil cooler to my current app then would that create a surge in the oil flow rate that my engine currently has.

Shouldn't cause any kinds of surges.

The oil will just be cooler than normal operating temps. This could potentially lead to slightly worse gas mileage because oil thins out as it gets hot.

never really looked at it that way. you have just proven a strong point. wow. Im already running a 180 thermostat. and the colder the oil the thicker it gets... hmm

Plus cold oil doesn't lubricate properly, so you would be extending the warm up period for the oil to reach it's designed operating temp, further increasing engine wear. I don't know how cold it gets where you live, but if the tempereatures reach over 95* - 100*F I could possibly see a cooler with a thermostat like Perma Cool sells so the oil will warm up, but not get extremely hot. I know the t'stat works great on the ATX. It doesn't flow to the cooler till 180*F As far as the coolant t'stat being 180* your oil will generally be hotter than your coolant but it is made to run at prolly 200 to 240 degrees ( i'm sure racer12306 knows the operating range

). Which if you think about it you can't bake a cake at those tempereatures, just to put some perspective on it.
