Oil Coolers...
Anybody have any experience with aftermarket engine oil coolers? I'm trying to find out how much of an engine temperature drop I would get if I added an oil cooler, say a relatively small one. Anybody know?

I understand that. However, that's why I was asking if anbody had any experience with them as to their effect on engine temperature. According to Perma-Cool, they claim that their oil coolers will maintain the oil temperature at 180-200 degrees. They claim that the oil is 20-75 degrees hotter than the engine coolant temps on a running engine. It would stand to reason that if you could cool your oil temps, then you could cool your engine a bit as well.

Anybody have any first hand experience with the addition of an oil cooler and how it did or did not drop the engine temps?

my 390 runs 220 degrees oil temp. it is very close to the 210 water temp. the thinner the oil the faster it will remove heat. when i was runnning 20w50(bad idea) it was 235 steady went with 5w30 ( good idea , uoa showed perfect numbers) oil temp went down to 215-220. a oil cooler is really not needed.

I run an oil cooler...
The oil temperature is usually hotter than your coolant. That should tell you just how critical it can be to keep the oil cooler. And how much heat the oil is actually carrying off. I run an oil cooler on my 390, and I get a 20 degree temperature difference with ambiant air; no fan. Here in Nevada the pavement temperatures get well over 130 degrees and that doesn't leave much to cool the radiator down with. For every degree you can cool your oil, you add life to both the oil itself and all the critical moving parts. As Ford390GasHog says, "The faster the oil moves, the more it cools." So the oil is important also. That's why I run synthetic oil along with the cooler because the synthetic oil moves faster through the system, adding to the cooling effect. How much do you like your truck? Wouldn't you like to give it any edge you can? Keeping the oil cool also make it easier for the "other cooling system" to work.
