The oil cooler/warmer is still working great, no issues. I do have a question about oil viscosity though. Normally I use 5W30 since I am making an estimated 20-30 HP above the stock rating and I frequently run the car hard, but now that I have effective oil temp control I am starting to rethink whether I wouldn't be better off with a 0W20/5W20 oil.
With this cooler the highest oil temp I see during normal use is no higher than 190 degrees, so I'm thinking adding the cooler is pretty much already the equivalent of using one step above the factory recommended oil grade if not probably better. Thanks
