Well here it is...BS was pretty quick this time, only a few weeks which is excellent (to me) - maybe they read this forum and saw all the fussing/issues folks were having. So this one is interesting. This is HPL Euro 5W40 changed out in Jan 2024 and has 8.4K miles on it and 8 track days which should be around 10-12 hours with oil temps at 260-280 deg F. It's been beat on. A few issues I had were that I did note that my air filter had come off when I was doing all my annual maintenance so not sure how long that had been like that and that is the likely source of some of the up-tick in wear metals and obviously Si; I had all sorts of stuff loose (connectors) and I think I just beat it to death over that 4 days so maybe it only happened right at the end of the OCI...too many crubs...BRAAAAP! This is a dry high-flow filter. I pulled a mid-year OCI and I left that in the data (June sample) and as you can see with the /1K mile rates, it ticked up after so guessing that's also when the filter came loose but I also had only 3 track days on that sample with the remaining 5 on the back-half of the year/sample.

Interesting stuff, I'll likely just go back to a 2/year OCI to be safe and base it more on track use than street use/miles. In 2025 I plan 2-3 days the first half of the year and like this year, more in the second half so I'll just do a mid-year change I think. At least it's based on data, not just gut feel here. I really need to sort out my intake...I really like the Unitronic carbon fiber one I have and it's closed which is nice from a heat soak perspective (even though once that slightly warmer air from a "filter on a stick" intake hits the turbo it really doesn't matter...the intercooler efficiency is more important at that point vs. 20 deg higher air temp hitting the turbo). I'd be lying if I said I didn't love how it looks under the hood. I never had much issue when using an open intake with a K&N or my original OEM intake bits with a drop-in K&N so maybe I'll go back to something like I had (Neuspeed P-Flo). Also note my Si values were v. low/normal since having that intake (intalled mid-2022). I tried to find an oiled K&N filter that fit this one but I there just isn't one. I bought this intake used and can easily sell for enough to cover a new different one. I'll just keep a closer eye on the intake parts to ensure they stay put!

Viscosity hung in there (just slightly out of grade to a 30 - note BS got that wrong in their comments...40 grade starts at 12.5 cSt. It's a testiment to the HPL Star VIIs and the overall base-stock quality - if this were any other oil it would have been in the 10 cSt for sure. Go HPL! I'll be running a leak-down test and borescope inspection before year-end and will post up the results to have a look at overall engine health; last year I did a compression test and it was 180 across all 4 but leak-down is a better way to go here. I believe with better air filtration my wear values would be just fine considering the use. Next results due from BS are my DSG fluid.

Keep in mind this 1.8L turbo-charged 4 cylinder is at ~400hp at this point...I've had it 6 years this month.

Here's a video of my PB run at VIR a few weeks back:

Visc. did hold up pretty good for your type of use and mileage. Sux the filter came loose & probably during track use?
Keep the rubber side down. :cool:
Yes had to have because the more I think I had the intake off before so that was at the track. Just something else I'll check each day at the track.
 
The numbers are pretty good considering you are pushing her hard and the motor is pumped up/
 
Also of note, per Lake Speed Jr. in his live Q&A video, he has landed on 5ppm/1000 miles as a good number to shoot for to be below. In my dataset, only one Fe value was above 5, even the current values are below....good enough for LSJR...good enough for me!

Too bad so many of your reports are skewed by some issue or another.
Would be cool to see HPL operating in a perfect environment, but hey, that's real life and real drama!
Amazing to see the viscosity hold up to that abuse. Moly is crazy high :0
I don't think I'd use any other oil for your application.
Thanks for sharing.

Agreed, really wish I had a normal run but as you say life happens here.
 
Totally forgot another potential impact on this UOA...I replaced the HPFP with a larger OEM part for a revised tune I'm running now. That definately will shed some level of metal to the oil based on that it operates off the end of one of the cam shafts with a lob/new vacuum pump that all are lubricated from the oiling system. I suspect some of the metals this go are from that.
