Oil Temp On Track

[Aazzy]

Took the s13 out on the weekend, it's running a 285rwkw rb26dett, and I'm finding that engine oil temp is getting upwards of 120 to 130 degrees when I really start pushing the limits. It does have a reasonable size cooler. And at the moment i have ulx 110 in there. I'm curious to know what everyone else's temps are, It just seems a little too hot. The front bar will be coming off anyway as the next meet Won't be till late January, and I'm looking at running a whole heap of air flutes/ducting anywhere I can fit it.

I saw 140+ in mine after a few laps in summer, that was with a 30 row expensive cooler, running a 14 inch thermo fan. A good synthetic will take it though.

That said, we had to tape up all the coolers on the the Gibson GTR the other day at Sandown as nothing was getting up to temp after 8 laps.

I was up around 130C at Winton on the weekend with no oil cooler

good grade 4 syn will take it, just don't use some magnetec shit and expect it to last

I would try to keep it under 130 though, at 140 it starts to really thin out and start to break down

yea magnatch rocks

i have also noticed it doesnt heat up as much as my current synthetic

mind you it does pick up the e85 more

[Dose Pipe Sutututu]

ok, now you guy are confusing me

it's a $22 oil (when on sale at Repco)

[scotty nm35]

So is GW Synx3000 but it's quite good if you drop it regularly. Full synthetics like the heat more though, and will last longer, but who cares if you drop it every track day...

Only reason I am running Penrite racing 10w40 now is after speaking to the penrite rep, he showed me oil analysis results between the various oils in their range, from actual race meets, and the racing synthetic is perfect for high track temps, the film strength remains for much longer in track conditions. High Zinc levels, SN rated for e85, and It's a reasonably priced oil too.

penrite runs 20 degrees hotter in my gtr after 10 laps

magnatch is cooler and cheaper to drop every 300km

[scotty nm35]

So does that make the oil better? I would have thought the oil which is hotter is doing a better job of removing heat from the piston crown, which is a good thing.

I agree though, if you are dropping your oil every 300k's it wouldn't really matter what quality oil you run, other than Magnatech? Are you kidding me? It has the worst name ever for sludge creation doesn't it? So many people have warned me away... I would be too scared to try it.

I just buy magnetec for my shitter Accord V6 and drop it every 5000 km as it's $22 LOL

For the fridge I just run Mobil 1 ESP 10W40 and it seems to be good for street & track, don't really have any heating issues as car still makes pretty homo power figures

[fatz]

ive been running it for years in track gtrs

never had a drama, only changes top penrit because the priice of magnatch went up

[Dose Pipe Sutututu]

I'm still a tiny bit sceptical but I guess if it's a per oil change per track day it should be good right?

[fatz]

one e85 i go every track day ( thats with two drivers)

on bp98 i could use it for 3 track days ( once again two drivers)

[niZmO_Man]

Pete dumps the oil after every track day, so I don't think the oil has time to break down and sludge. Helps when you have a trailer so you don't have to worry about driving it home .

At the last track day, using Penrite Racing 10W-40, I was regularly hitting 130°C lol. Car still drove home fine, dumped the oil after as I didn't want to risk it. Oil was about 3,000 km when I hit the track lol.

[C4a0s]

what abt the "weight" of the oil like 10W40 vs 20W50 etc? what are you guys using for the track? true that oil thins out at higher temps... but if u use a "thicker" oil? any comments?

[Dose Pipe Sutututu]

many of my mates use 15W50 but really depends on what temps.. I'm using 10W40 but my temps usually don't go past 120 (low powered fridge with huge oil cooler)

When i put the oil cooler on my 32, 1st track day the temps went to 130+ so went home pulled it apart and freed the thermosate and put it all back together and I haven't seen it go past 110 on the track since, 16 row no fan, if I saw 140 with a cooler that big I'd be looking long and hard at it, then tell someone to fix it !

I used to run Nulon 15-50w street/track, I now use Brad Penn 15 or 20-50w, the green oil
