A 2018 fb25 subaru towing a trailer up to the Eisenhower tunnel with coolant temp within control of fans and 200 degrees coolant, for relevance. Oil was 261 going to opposite direction a few weeks earlier in warmer outside air temp.
Here's what I do to HPL oil

Beautiful machineMy BMW daily is my track car too.
Upgrades that is
So, I got this BMW E90 328 xDrive with 6-speed manual in December 2019. I was looking specifically E90 with N52 (last naturally aspirated I6 engine that BMW had). I had several criteria:
1. Must be manual.
2. Must have below 100k.
3. LCI (updated, so not older than 2009).
4. No iDrive.
5. HiD lights.
6. Sports package.
7. xDrive bcs. I would take it to ski.
So, after looking for a year since I got rid of X5 for Sienna, I found one in DC with 84,000 miles, flew there, and drove it back in two days to CO.
The first purchase was 16" wheels with Continental...
The beatings will continue until morale improves 
Wagon Queen Family Truckster ran well. Nice cold temps in morning meant that turbo was happy. Oil temps 270-280 deg F '18 Z06 Vette in bay next to me sees 290 deg F.
New PB today at VIR.

2 days at VIR in the books. Car ripped/no issues. Got a PB…shaved 2 seconds off my best lap which is great. Felt good. Nice cool temps with highs in the low 60s and lows around 40 in the morning…turbo loves that cold dense air…you could see it in the max speeds on the straights during the first session and see it drop off a bit over the day as it warmed up a bit. Never saw the coolant gauge move (just means it was under 220 or so…dummy gauge) and oil sat around 270 when I was pushing. No issues and never had to back off and run cool down laps.
First time at VIR since installing a catch can with my upgraded OEM PCV (from a MK8 gen engine, uses a second vacuum source from the turbo to help maintain more consistent crankcase vacuum/prevent oil ingestion/smoking after hard braking/high-gs…a common issue on the MK7 gen [GTI/R/Alltrack/Sportwagen/GLI). The catch can was sort of an experiment…typically they are unnecessary on the stock PCV but I am getting some oil in my charge pipes/intercooler after track use so figured it may be a nice housekeeping addition. Sure enough, after a session I had about ½ a can full which is ~3oz. I emptied it each time for 8 sessions so about 24 oz/around a half qt. I just dumped the contents back in the sump; the second morning it was full of condensation (looks like coffee) so I dumped that out obviously….must have been from the hot engine cooling/cold temps. It was always oil otherwise. So I kept ~½ qt of oil out of the charge pipes/intercooler and had to add a qt so ~½ qt “real” consumption out the exhaust pipe…pretty normal for track use. The can is slick and has a valve that when full, shuts off the can and just passes the vapor through to the turbo inlet so you don’t blow anything up. Normally I don’t get much but a few drips in it for street use over time which is to be expected. I’m sure I’m getting a bit more blow-by than normal with the 25 psi boost this tune runs.
Cooking a burger on the turbo.
Best lap.
Also noted that my garage-mate with a 2018 C7 Covette Z06 (BEAST) had a bottle of Mobil 1 15w50 on his bench. Figured folks here may be interested in that haha. I’ll likely do a 5K change vs. the longer runs on HPL I did the last 2 years this go…that will be ~4 track days and an autoX. I’m very curious if my oiled Uni foam pre-filter will reduce my Si and wear metals a bit.

Last HPDE of 2025. Cold mornings around feeezing but mid-day was perfect. Cold air = power on a turbo so got a PB. Colder temps also easier in oil and coolant temps. Not my best driving but I'll take 0.7 sec/142 mph vmax on back straight! Had an oppsie too...gulp...
HPL will see 3 track days and a few autox this change and will do ~5K to see how my air filter setup is working.

100%. "Should I use no-VII for 3k miles ocis? , I'm scared mommy." It's hilarious.@TiGeo is HPL user of the year. Meanwhile we're all like "I ran HPL for 5k miles to the mall check it out."
Me: 10k/multiple track days at 270 deg F+ oil temps. "Hold my beer."

Recent used oil analysis thread:
What? Just email again or call. They have an excellent track record of working with BITOG users. Maybe got lost in the shuffle or they couldn't understand what you were saying?
I mean dude...just call them. Send a DM here to them. @HPL Plant Manager @High Performance Lubricants
Latest HPDE/track day....this time at Summit Point, WV and finally got to the "main" circuit. Great track...fast and flowy and relatively short vs. VIR. Ambients in the mid-80s so had some heat management issues...mainly just had to run the heater on full while on track and just be cognizant of the coolant temps backing off/cooling down when necessary. Oil temps 270-280 F like normal. Only excitement was a car behind me that was gaining/I was readying for a pass had their front wheel fall off and slide into the wall. Totalled. He was fine. Had track insurance thankfully. CHECK YOUR WHEEL HARDWARE EACH LAP. Here's a lap around Summit Point:
Rear pads after 4 track days. Paid for whole pad/got whole pad! EBC Bluestuff NDX (~$130) on the factory tiny little 272x10 (solid) rear setup. You can see the friction material retaining "hooks" showing. Was loud and I could see the rotors getting marred from it.
Ive had a few interesting things happen when I used to run on Summit Main in my first turbo Tercel.
Ive had an axle nut back off. Lost 2 sessions trying to figure out what was wrong then saw the cotter pin and nut cap was missing on the right front, wild.
Another time one of my brake calipers had started to stick slightly, glazing the pads and the fluid, which led to me doing the ol' 5-7 shortcut thru the grass.
Last thing...I was tailing a c5 thru 10 slightly below my normal pace and didnt realize he had dropped some fluid as I went full sideways then yeeted track left. Came back onto the straight gentle and controlled. Get down to 1 and the car skids all about. I come in, tell them what happened and then 2 other cars went off track behind that same c5 and he got black flagged.
Check out my new hood louver! Heat management is a big issue on this/these cars when used on track. Some folks add an oil cooler, I'd prefer to avoid that if possible. This is step 1 - more air flow/heat removal. I also run a 70/30 water to coolant mix with a water wetter. Next is possibly adding the aux radiator from the Golf R/S3 over on the right side (fog light area) to bolster the cooling system. Oil temps on track can reach 280, DSG (trans) 270, and coolant 240 if I push it without backing off in 80+ deg F temps. Running the heater helps/pushes off the necsssary cool-down lap(s) but in the end...pushing this car will eventually overheat it in warmer ambients. Oil and coolant and DSG fluid and coolant share heat exchangers so in the end, the cooling system getting more flow/more heat removal should help. We'll see in a few weeks when I hit the track. I've logged some basic driving around and *think* I'm seeing lower intake air temps (IATs) so the intercooler is *maybe* seeing some efficiency gains....links in the description to some wind tunnel testing and you can see a CFD model of the MK7 Golf with the low-pressure zone where the louver goes.

Those hood vents are rad AND functional
Nice work!
Nice work!
