Oil needs to be a certain temp to burn off contaminents. You don't wanna run it too cold. Your Jeep was likely running better due to cooler intake air temps, big difference between that and oil temps. Colder ambient or intake air temps, the air is denser and contains more oxygen which is where the extra power comes from. A properly running engine will maintain the same operating temp whether the weather is hot warm or cold. hth

Umm, no, definately not an aircooled engine. The temperatures vary here from 120 to 30. I can tell you with absolute certainty that on cold days the engine warms up much more slowly than the warmer days and will get nowhere near the same teperature even after 30+ minutes of riding.

Actually I was slapping my head cause a jeep isn't air cooled and that's the context I was referring to when I said what I said.

In a nutshell, the OP isn't going to find any HP in his motor by adding an oilcooler UNLESS it was running hotter than it should due to a problem or it creating more heat than it was designed to handle because of a bigger motor, higher compression or someting like that.
