Also, as someone suggested, unless you're going with a big core, you won't see much of a change. Installed such kits, and every time I had to double the size of the cooler to make it significantly better than OEM water to oil coolers Sure, coolant temp is much higher than air and you'd think rate of heat transfer would be severely inhibited, but you should also keep in mind that so much coolant passes through that heat exchanger; the "mass" of coolant passing through there is massive, pun intended. If I recall correctly, the heat exchanger on my Corvette has 80K BTU capacity; that's nothing to scoff at .. If you're worried, send it to Blackstone for analysis, and check if your oil is holding up. The odds are you'd be impressed how good synthetic oils fare...

I didn’t cavalierly dismiss the idea of getting an oil cooler. I looked into it and the more I researched the more I realized I just didn’t need one for my street/track usage Quote:

I know this is basically a Mobil 1 advertisement and I will keep my oil cooler but it is interesting.

I’m in ZDan’s camp. There is no compelling reason for the oil cooler on the Gen 1. Plenty of OEMs and oil manufacturers have no or minimal issues bringing oil to 270F if not 320F as do race teams. Increase the viscosity appropriately and change it more often and all will be well. My E9X M3s would routinely hit 270-280F on track with a cooler and BMW Motorsports response was use correct 10w60 oil and don’t pay it another thought. My F8X M3s rarely hit 240, but they were spec’d 0w40 and later 0w30 and had the cooling to support that spec. Last edited by DrinkenBRZ; 07-31-2022 at 01:15 PM. |

If weighing a higher viscosity oil against using an oil cooler then it seems that the choice is the lesser of two evils which would be higher viscosity oil since an added oil cooler is just more mechanical complexity which could lead to other failures and complications. I guess it's a question of to each his own then. |

Have you ever seen the rod bearings on a S65 with that kind of use with and without a properly sized oil cooler? Why do you think that BMW went to a thinner oil with more bearing load (boost)? |

The temperature disparity you mention wasn't reported as an actual difference. KillerB observed a difference between their calibrated sensors and the factory sensor. I more wonder about the actual temperature rise as the oil circulates through the block after being cooled. I don't know if you know about my oil cooler. It's just a long-running experiment in measuring what it takes to control temps in the widest operating conditions.

275F is not a problem for any decent synthetic oil. 30wt synth at 275F has about the same viscosity as factory 0w20 at 250F In my experience oil temperature in the gen1 climbs up towards 270-275F, but reliably holds there, never goes into runaway overheating. I honestly think some are *adding* risk (and $$$ expended) getting oil coolers for these cars. IMO our cars are fricking *good to go* for track usage, as delivered. |

Bearing issues with the S65 are independent of the oil temps. They are theoretically related to insufficient bearing clearance, and yes I’ve seen hundreds of examples. Extra clearanced bearings often showed normal or minimal wear. OEM spec always showed excessive wear including ones operated at temps believed to be the magic temps discussed here. I assume BMW engineered robust cooling to accommodate the lower viscosity needed to meet fuel economy goals for situations where boosted M cars were going to be operated at full or close to full pace. Oil temps in the S55 rarely deviated much street to track in mine and others experience. If one were to run an FA20 at full race pace then a cooler may make sense, but not for the street and not for us weekend warriors. And if in race pace temps are not going north of say 280F I’d question the need for one more failure point with adding a cooler. Oils and engines can handle these temps today unless the flat engines have a weakness that other designs don’t. My educated opinion of course. |

I regret trying to engage in a good-faith discussion. Carry on, sir.

You guys just need to test and measure if you want to change brands/weights. KNOW you're making a change in a positive direction. There are so many factors that contribute to best oil for YOU, there is no one right answer.
FWIW most Nascar engines use 0w-20, but depending on conditions, will go down to 0W-5. |

I'll stand by this. The volume between valve cover and head shouldn't be "full of oil". I *think* that block temp and valve cover temp should track more with coolant temps than oil temps. But in any case the '15+ coil packs seem to be very reliable for track usage with or without an oil cooler. If/when one fails I'll replace it, perhaps replace all of them and figure I'm good for the next 40+ track days and 70k miles. |
