Here's what I do to HPL oil
- Thread starter TiGeo
- Start date
Just did one of SCCA's (Sports Car Club of America) "TNiA" - Track Night in America events at Dominion Raceway in Spotsylvania, VA. An inexpensive casual track day/HPDE-style event. Ambients in the low 80s and humid. My PB lap here. Shaved 3 seconds off my last time there in 2023, new tires are to thank:

If anyone is interested, here's a datalog from a session:

Lots of heat management issues yesterday - had to run my heat during the sessions to keep coolant below 240 with oil at 280 and DSG at 260 (see log). Short tracks are tough b/c no time to cool down.
HPL Euro 5W40 has ~7K miles so far with 3 track days and 2 autoX. I lose about 1/4 qt per day.
If you want to see my wrap-up/thoughts including my catch can/PCV setup, tires, heat management, etc., check my channel from the link above and find the video I uploaded today, some profanity so can't post the link/BITOG rules.
MPGs on the trip to the track:
MPGs while at the track
(I see 6 at VIR!):
Vitour Tempesta 200tw P1 tires (245/40/17 on 17x9 et 42 Apex VS-5RS forged wheels (~17 lbs). 2 autocrosses and 1 track day so far (rotate every event fronts to rear and rears to front cross) plus ~-2.7 degrees camber in front. Order is LR/LF/RF/RR:
