I had issues with oil temperature here in Colorado, but High Plains Raceway here is between 4,900-5,200ft, which puts a lot of strain on cooling system.
That being said, I would still do some retrofit. I am doing oil cooler now, stock from N55. But, you really do not need that IMO in CA unless going to some high altitude tracks. What I would do is go this route:

That is much cheaper than dedicated oil cooler, as with oil cooler there are numerous other stuff that needs to be changed. This heat exchanger is pretty simple, effective, and in normal driving might save you some fuel as it will accelerate oil warm up. There is one more coolant hose you need to add if manual, not sure about automatic transmissions. But, search on Google, there are threads by people who did it.
I would go this route before you go bigger radiator.
Also, code your mpg gauge to oil temperature gauge so you know your oil temperature. |
thanks for the suggestion. I have known about this heat exchanger that exists on some x3 n52 and some other models. do you have anecdotal experience with it lowering Temps on track before and after? I have the sports package in my e92 so it already has an oil gauge. thank you for the information
