Anyone ever use the light shockproof in any PTUs? This is in a Volvo that that gets tracked a bit. Sees no low temps. Factory fill is 75 or 80/90. I switched to SV 80/90. This thing gets HOT, 300f is very common. Probably part of the reason is that it splits power 50/50 in sport mode, so its loading it pretty hard. Gets hot enough you can smell the gear oil stinking/off gassing out the vent after a 30min track stint. It turned the SV quite dark after 3 stints. I'll do a UOA when I change it, but I was going to step to SV 75/110, but I wonder if the light SP would be better?
