What is the safe oil and water temp on track?
My car is the N55 M2,
I'm running Wagner EVO2 Competition intercooler and BM3 Stage 2 91oct tune. I got max 125C(257f) oil temp and 105C(221f) water temp until I stopped pushing it. What's the safe zone for our cars? |

Those temps are fine.
See the guard and emergency temps listed at the bottom here: https://www.newtis.info/tisv2/a/en/f...oling/F7kt8r2W |

Wow, 302F oil temp before guard mode, and emergency mode up to 325F. Now we’re cooking. I was expecting 270F to be the limit. Good stuff, thanks for posting!

You can also use BM3’s MaxCool mode on hot track days to keep things cooled off more before you start pushing. I figure it’ll buy you a couple more laps on a hot day, but I haven’t tried it on track yet.
If you ever get to 242F coolant, you’ll feel the car start to pull power and shift earlier—it’s pretty noticeable. If temps continue to increase you’ll also get the guard message on the idrive screen saying you need to drive easier. I’ve only seen the emergency message on idrive once and I figured it was time to back down! Overall, it’s pretty amazing how well newer cars can take car of themselves with high temps, but if you’re mod’ed much and are pushing hard and if it’s summertime, these are things to watch for. I have my phone mounted and my BM3 dashboard up while I’m on track, so I’m actually keeping a very close eye on coolant, oil, gearbox, and IATs. Last edited by ZM2; 06-28-2020 at 07:38 AM.. |

I'd be very concerned about oil degradation at those temps. My E90 M3 would push to around 270f on track, but it runs nice thick 10W-60 which can better withstand the heat.

I also run half E85, so that thins the oil some and the thicker oil helps to keep from burning as much. Last edited by ZM2; 06-28-2020 at 05:22 PM.. |

This is an indepth guide to bmw's limp mode temps: https://www.e90post.com/forums/showthread.php?t=412156 Quote:
That being said if you do not want to flush your oil out constantly from running a track oil like 300v which is not really suitable for daily use as it is not LL01 certified meaning it does not have a suitable NOACK rating, and additive packages might not be up to speck I would stick to a daily use oil with high enough specs that can handle track duty. So this would mean something like valvoline full synthetic advanced which has a pretty good tbn rating, and has an HTHS of 3.7 which is quite good. Or my personal choice penzzoil platnium euro 5w4 which has really good TBN ratings, excellent NOACK in the 6% range, and a HTHS of 3.6 which is equivalent to motul xmax 8100 0w40 at 1/2 the price with equal specs (this shows price is not a good indicator of oil performance). Penzoil platinum euro 5w40 also has a better NOACK, higher HTHS and better specs overall than liquimoly leichthauf 5w40 as well (again this shows price is not a good judge of oil quality). Then comparing to non-LL01 approved oils (but they are claimed to be by the manufacture, maybe they meet LL01 specs but bmw never liscenced them who knows but some of them do not meet the NOACK rating though) such as ams oil european car formula 5w40, and redline professional the specs are similar to Pennzoil but the only benefit is that it has a 3.7 HTHS rating vs. pennzoil with a 3.6 so not much better for 2-3X the price. So overall penzzoil has a really good HTHS rating for a 40 weight oil and it is near the top for LL01 approved oils at a fraction of the price so this is what I personally will run when I run out of free oil changes. If you want a really do not care about LL01 approved oils and want the best 300v is your choice (but you probably will have to flush your oil loop out so you get the best characterisitcs of the 300v oil and have it undiluted by the stock oil which will cost alot and you have to flush it to go back to the street), if you do not want to pay 300v money redline has a 5w40 oil that is suitable to be a ll01 replacement (even though additives or composition of the oil, prevents it from being certified as a real LL01 which is why it is not LL01 approved) and has an HTHS in the ~4.4 range. So this redline is what I would run if I only wanted 1 oil for street and track and did not care about LL01 but didn't want to stray too far away from what bmw recommends to avoid carbon build up etc. Here is the bmw LL01 approvals for anyone interested (please be careful not to fall for the manufacture's tricks saying an oil is recommened for LL01, or meets LL01 specs because they could be misleading you, so always check this guide by BMW which is semi regularly updated to be sure) :https://www.newtis.info/tisv2/a/en/e...ply/1VnYpiUbyG PS: Sorry for the rant which may be incoherent, feel free to ask for clarifications.

Yeah, a good point that is often missed is the non-LL01 oils should be changed sooner. 300V is 3-5k miles. I mostly drive on the weekends and the track, so the mileage limit works for me. Does Redline mention a mileage life amount on their high HTHS oil that you mentioned? Switching back to coolant temps: I’m going to flush with distilled water and a wetter this/next week for the summer. Should improve heat removal by ~20%, which is significant for those of us hitting 240F+ coolant temps on track. Boiling point should be around 250F under pressure, so will keep an eye on that as well. Last edited by ZM2; 06-29-2020 at 07:52 AM.. |

My M2C has 5K miles and is about to get started tracking in 2 weeks (finally!!) so I'd like to change the oil prior. It's had one change to date, the running in service at 1K. |

Funny thing is here in EU the OEM recommendation is every 2 years, or 25,000 km. So 2 years or 16,000 miles. I had it changed in March of 2019, I did 3 track days last year, and starting this Friday I'm back at the 'Ring. Computer says 16,000km left till the next change, or March of 2021. I don't plan to touch it this year even with extra 4 track days. Wish me luck though I'm sure BMW knows what they're doing.

Remember guys I am not the ultimate expert in oil if you want even better advice go seek out the guys on bob is the oil guy. But I have learned alot from reading an extensive number of posts on there and what I recommend is that just because an oil is more expensive than another oil does not mean it is better, for example penzzoil vs. liqui moly. The penzzoil has better NOACK, and better HTHS, with similar additives but at a fraction of the price. So no need to waste money on more expensive oil if the cheaper one is just as good and can protect you on the track. Also just because one oil has alot higher HTHS than another does not mean it cannot handle track temps, I believe above 3.5 is good. The final thing is everyone's driving is different so do a used oil analysis on your car to ensure the oil is holding up, speculation doesn't mean much compared to real data.

Make sure you do oil changes at half the recommened interval to lengthen the life of your car.

Interesting. The Redline & Motul are about the same price, so maybe I'll try the Redline next time around. Altho, I was very impressed with the oil temp reduction with 300V, esp as someone who's battling engine temps, so I'll see if the Redline has the same impact. As for coolant, I put this link up in a different post, but it's always an interesting read: https://www.redlineoil.com/Content/f...ech%20Info.pdf Redline seems to think they have enough corrosion protection in their product, but it's unclear if that's blanketed with still using some glycol. What is clear is how much better water absorbs heat than glycol. |

Woah yeah it's alot more. 300v is definitely better for the track but not suitable for the street. Redline should be better for all around and good for the track too with that super high hths rating.

The 300V has been great, but I’m all for more additives if they help. With similar weight and HTHS you would think think the Redline will have similar lowering oil temp effects as 300V. I’ll try it later this year once my 300V is done. Last edited by ZM2; 06-30-2020 at 07:32 AM.. |
