Seeing as this thread pops up anytime anyone votes I thought I'd add my 2p worth.

My oil is never hot if I drive the car easy. Ok, I don't thrash it much ( and I never have done with any car) but I think the highest I've noticed is 76. It's usually 71 or 72 when driving normally. In saying that, it's been cold since I got it so I've never seen it in traffic on a hot day.
On a hot day in stop start traffic for 30 mins plus will see around 92+.

Shocked you haven't seen higher than 76, has your car ever seen any boost lol? Those turbos must be in a coma.

My 32R on a 25-30 degree day on the track saw oil temps reach 110 easily after a few laps. After one or two cooldown laps it would drop, and then I would do another 2 or so laps before it hit 110 again. Running Motul 300V 15w50 - No extra oil cooler.

On the streets I see 70-90. Last week it has been re-tuned with a Link G4+ N1's on 15psi and on high boost it creeps up to around 90 pretty quickly!

Will be installing a oil cooler soon before I track it!

Looking at the temps you guys have posted, there are a few cars where the oil isn't getting hot enough you want it to get over 70-80C as some of the additives require heat to work properly. You don't want to overcool the oil, 100C is ideal.

Also, the temps are generally within the safe tolerances for a quality 5w-40 (up to 130C average, with higher peaks). Perhaps with a forged build a 10w-50 would be better if the temp gets over 115C or it burns much oil.



On a hot-ish day (25C) with an HKS oil cooler located behind the passenger side indicator (removed the indicator for trackwork) I never got above 110C. However the engine dumped a lot of oil past my Mines head baffles and into the catch can and rear turbo inlet. It also does this on drag races with lower oil temps btw (turbo restrictor added btw).

Would I benefit from a thicker oil?

90000km never opened engine (as far as I know)
GTSS turbos 1.2 bar

Street and track use 1-2 oil changes/year, currently running Gulf competition 5W-40.
