156F is too cold for oil. That is not up to operating temp, and because of this your oil is too thick. Oil is rated hot at 212F and running it cooler than that is not good. Hotter is better than too cool. SRT will state that 300F oil temps are nothing to worry about with penziol ultra, a high quality GRP III oil. Unless you are seeing 300+ oil temps, an oil cooler is not necessary. An oil cooler will reduce flow in an engine as well. More distance the oil has to travel which equates to more fluid drag. Also with oil that cool, contaminants such as gasoline, and water will not evaporate off as effectively.

Moral of the story is you should use a good oil such as 5w40 rotella t6 and change it every 3000 or so.
