Some of us use the BRZ as a track car AND a daily driver and that just isn't practical. Millers Nanodrive is not cheap oil I don't know what a "track season" is. I go every chance I can get throughout the year. You know whats nice? Boosting the shit out of my outback over and over while laughing in the dadwagon and seeing oil temp get up to mid 230s....then lay off for a second and instantly goes back down....cause Millers isn't cheap for that sucker either Last edited by s30series; 08-26-2021 at 12:16 PM. |

We'll have to agree to disagree, I'm not changing my oil on my daily driver once a month... $60 a month gets old QUICK It's not about breakdown of the oil from the heat anyway, it's about how thin it gets. Yes better oil helps, but you're still going to need to change it often when it's getting that hot. Just spend the $500 to add an oil cooler and it'll pay for itself in a couple of years of tracking while also better protecting the engine in the meantime. For the record, 254F in a single lap with chicanes at Monticello is pretty hot. Like barely better than the FA20 without an oil cooler... It's not like it reached thermal equilibrium in one lap so surely it was going to get hotter.

You choose viscosity based on oil temps, it's not a big deal. Quote:

FWIW my '17 only gets to ~235-240F in one lap, I bet the new car's coolant/oil heat exchanger has it starting out at a higher oil temp but may have a lower equilibrium temp vs. 270F +/- a few degrees for my car. |

Even harder to say which of two risks is actually higher. Most people with FT86's seem to agree that the risks associated with running the oil hot is higher than mechanical risks associated with using an oil cooler. I don't think it's rarely considered (I certainly considered it, and saw it being brought up in multiple discussions), but statistically I've heard of a lot more engines that failed due to lubrication issues than coolers failing. |

This is a weird conversation.
The oil gets hot on these new cars. Upgrade the oil cooler. Nah, don't upgrade the oil cooler. Change the oil more frequently. The oil cooler will pay for itself in the long run versus more frequent oil changes. It won't pay for itself if you change the oil at the same frequency as without one. What? |

My turbo Subis cook everything in 20 mins on warm days. My Brz sits on 106C oil and under 100C water (warm day 25C), with an oil cooler. The car needs warming up and not cooling down. Runs continuously with driver changes (Wifey and Me). Brakes run cooler Tires don`t go off easily. The car is slightly slower in PB laps and does more laps faster than the turbos without a cool down.
I change oil every 2 events or 5K of daily. 5w30 Castrol edge. |

TLDR: "A full-synthetic oil will withstand sump temperatures in excess of 300 degrees, and for hard-core professional racing, some oval-track race teams are experimenting with ultra-thin, specially formulated, race-only synthetics operating at 350 degrees or even higher." You're welcome.

I'm sure the FA20 & FA24 and it's bearing tolerances, oil pump, lifters, etc were designed with 300 degree plus oil temperature in mind. |

This "well the oil can handle it" narrative is almost comical. Heat is the enemy in almost all mechanical applications. Oil is not really even in the overall equation. Go to any track. The hoods are open to let heat out and never open because, well things are just too darn cool.
