What's the verdict on the need of oil cooler?
 

It may be still a bit early to ask such a question, but the tuners in Japan are claiming that 86/BRZ needs to install an oil cooler for track duties.

Has anyone been measuring or monitoring the oil temp at the track to confirm the above claim?

Thanks in advance.

need it

even on stock car

proof:

I was considering an oil cooler as a must due to the fact that I already have oil temp\pressure gauges installed ( Defi ) . They tell me the engine runs hot, even crusing the oil temp rarely gets below 95-100C. When you give your car some piece of a redline, it easilly climbs up 110-115C+. And that's not even a race or sprint - that's CITY (brave city, hehe) . Water stays dead 90-93 whatever happens. Never saw it higher.
I believe racetracking your BRZ may boil your oil without a cooler, so it's a must imo.

Would you mind posting datalogs? :)

which ones?

dont have any in logged format, just looking at the gauge is enough

if youre having fun and pushing this motor, SC or turbo, you needs an oil cooler
if you live in OC or climates similar to mine, even NA, you benefit one.

Here in NZ guys have reported oil temp of 130 on the track without oil cooler and we are in a pretty cool climate.

i have just put gauges in on tablet to check it on my next track day but these cars do seem to run hot in the oil department. On road driving, even keeping under 4,000rpm during run in the oil temp was around 100.

BTW @balance - nice gauge and single din stereo set up!

proves my words above

you have to be nice to the cooling system prior being rude with tracking your engine :respekt:


Just one more thing -
Remember we run very waterish oil (0W20 for 99%population, and 5W30 for 1% wise guys), which tends to thin out VERY much when hot.
Oil pressure drops more the more hotter you run. Think it over.

well, the answer isnt thicker oil its cooler oil..:D

This. Address the cause, not the symptom.

Does the car come with a oil temp sensor from the factory? If your sensors are aftermarket, where are you taking the readings from?

yes and obd2

Yes, there is an oil temp factory OEM sensor. The OBD2 connector sends it but the cheap OBD2 ELM327 senders don't seem to be much good as no-one has worked out the PID for oil temp.

I use an HKS OB-Link read by a 7" tablet mounted in my car as an alternative to a gauge cluster although I do like the look of that single din cluster of @balance above.

And a couple of threads discussing getting the oil temp over the OBD2 connector are here

MSTiFK8R and NZER,

Thanks for sharing your findings. What you guys have said pretty much echoes what I heard from the Japanese tuners. They also said that an oil cooler is a "must have" item even for a stock car based on track testings.

Now what I am curious is that why the heck toyota/subaru have released the car without an oil cooler???

I didnt wanna mess with tablets, computer, etc


I read both oil press&temp from the Greddy 12002802 sandwich plate under the oil filter

the gauge is DEFI DIN-GAUGE, showing also water temp via separate sender in the coolant hose

Any installed pictures (under the hood)? Did you have to use the little spacer to make room for the senders, or will they fit in spite of the oil cup?
