How do you guys Keep your Oil temps low
What are some good mods and steps that you guys have taken to keep the oil temps low? My car has the factory oil cooler but just isn't enough, temps easily get to 260 on wot runs back to back. Many talk about after market oil coolers and radiators does any of that help?

Do you have an older model year? They changed the scale of the oil temp gauge at some point because people were concerned their oil was getting too hot when it was normal. The old design had the center of the gauge at 210*F so the reading always looked "high" since it was way past the middle at normal temp. The new one is centered at 250*F.

Have you ever flushed your coolant?
Mine used to run hot too, going to 260-270 on spirited drives. I did a coolant flush and after that, the oil temp rarely ever goes over 250.

You'll add longevity to your engine by bringing the temps down so a larger or more effective oil cooler is a great idea, particularly if you live in the West/Southwest. I'm not quite getting these guys saying the car likes to run hot or words to that effect. Yes, BMW engineered the car to run at high temperatures (all modern cars do) but when they added an oil cooler (they didn't even think it needed one initially!), it was just large enough to solve the early running issues. Excessive heat is the enemy of a long lived engine.
If I lived in the Northeast or upper Midwest, I wouldn't worry about it, though. If I lived in Arizona, Texas, etc. and ran the car hard I would definitely upgrade the oil cooling. |

The hotter the oil, the greater the chances of it breaking down sooner. You want to be at a sweet spot where it keeps the motor at an expected operating temp while at the same time not being too hot that the oil breaks down.

THis is what you want. This opens around 185 I believe. So you still get your engine to warm up (which can be an issue for the BMS thermo delete in winter), but it also keeps you cooler. I have this with a second oil cooler I pieced together in addition to the stock oil cooler.

Engines runs best in the 180-220*F range. Contemporary engines simply run hotter, mostly due to emissions and, more recently, with more cars having turbos. Because of this we're seeing oil temps now in the 220-260 range considered normal (during Spring, Summer, Fall). That's actually friggin hot for motor oil. Synthetic oils can handle this heat far better than oils of yesterday but even they start to break down (as fazman states). |

Leave the 710 cap off for it to vent the heat.
