Or as someone else in one of these threads suggested, you could send a fresh sample of oil to Blackstone, then send another sample after tracking the car and see what they say about oil degradation and/or metallic particles. If oil isn't degrading and metal isn't being eroded beyond reasonable levels for your usage, why bother with an oil cooler? |
Because it only takes one instance of excessively low oil pressure to damage the bearings. The problem isn't about the oil itself degrading (it can take it), its about the drop in viscosity and oil pressure that results from elevated temperatures. Its the oil pressure drop that kills engines, and the main cause of that is high oil temperature. A thicker weight oil will help of course, but if you are tracking during the summer months there is no substitute for a quality oil cooler.
To answer the OP's question, I'd just get the Jackson (or Perrin for less $$) and hit the track with piece of mind.
+1 to getting a Blackstone test done every once in a while too.
