I had about a 20-25 degree drop as well with the single core stillen oil cooler... I switched to a custom dual core setup and I think it is more like a 30-50 degree drop

I am having the Stillen race oil cooler installed tomorrow morning. Like others have said, regular oil cooler will drop oil temps 20-30 degrees. Not sure what the big race oil cooler will do, but I will find out soon.

if anyone in Arizona region wants to replicate my dual core setup, contact Robert at Redline Motorsports... it uses two cores of similar size to the standard stillen setup, which is more total cooling surface than stillen 'race oil cooler' by a good margin... robert has not yet released it to the public as a kit but may do so in the near future

That Redline setup seems neat Travis.. keep in mind too that the STILLEN setup can accommodate additional coolers in a bolt-in configuration, you can run the race (or street) cooler, power steering cooler, and for the automatic guys the trans cooler without having to fabricate anything.

Does oil temp issue affect daily driving?
 

New owner and member so my bad if this was already threaded. Obviously reading about the oil temps issue everywhere on the Web. Seeing many posts about track day problems/road test situations but can't get a good read on whether its a problem for daily drivers? I'm still in break-in so not experiencing issue yet but live in South Florida where air temps will stay fairly high year-round. Hate to think an oil cooler would void warranty, but if daily driving in hi temps and/or highway miles put oil temps over the top, will need to consider it.

Thx

everyone has an opinion, and after experiencing a lot of these issues and fixing it, here's mine... for daily driving, if you have any three of the following you are likely to see temps over 260F and prob limp mode... just 1 or 2 then no worries!

- aggressive driving on the street, or lots of high RPM e.g., 1st/2nd/3rd in traffic
- driving over very steep gradients, 6+ degree continuous
- driving in very hot temperatures, 110+F
- manual transmission

The last one is controversial with some folks, but as it turns out if you have a manual transmission, you're much more likely to experience overheating... See data below from our forum survey.... We have basically zero reports of limp mode on the street with automatic transmissions, and very few reports of temps over 260F

This pretty much nails it, IMO. I have a MT, like to drive aggressive (albeit safely) winding out 2nd and 3rd, temps in summer reach 100F air temps, ambient pavement temps hit 115, and.... being on the coast I see a lot of inclines (bridges/steep gradients). This is also combined with a rush hour issue where, after some open road enjoyment, I come to a total standstill and crawl in thick congestion............ I hit 260 all the time in July and August. Now that it's cooler, the most I am seeing is about 240. Looks like an oil cooler for me next spring :p

Great info. Puts it together nicely. Thx! Have a 7AT and we're totally flat in this corner of the world. Temps are in 90's but not desert extreme. Think I'll play the odds, watch the temps and wait it out a bit.

you're welcome! :tiphat: i just arrived in florida tonight and it seems things are cooling off a bit... good times

My 6MT 370Z has about 1500 miles on it now. I did the first oil change last weekend and refilled with the Nissan ester oil. Yesterday I took a drive up to the mountains here in SouCal. It's been unseasonably hot, with temps in the high 80's. I drove the car moderately hard on the way up the mountain highway and the oil temp stayed between 235-240 degrees. On the downhill run I wasn't running as high RPM's and the temps were between 220-225.
I will comment that the lower end torque on this car was more than I was expecting, it just kept pulling going uphill with little need to grab a lower gear except on very tight corners. Impressive !

I did a track weekend last weekend at Putnam Park, Indiana. In my third session on Sunday, I hit limp mode. Oil temps were at 262 or so; I have the stillen "street" cooler installed and run on 275 wide street tires on all four corners. Ambient temp was 70 degrees and I was driving very hard. The stock fluid in my clutch hydraulic system also boiled and changed the way my clutch pedal felt but the clutch still worked okay. I'll be upgrading this fluid to Motul RBF600 and that should fix the problem.

Please describe the 'limp mode'... I strongly suspect you had fuel starvation, if you were only at 262. Please read the fuel starvation thread. It hits even at 3/4 tank if you pull 1.0g for 3-4 seconds (always right hand turns). Some of us are looking into baffle cans that will go inside the fuel tank as remedy. Good idea on the RBF600, that's what I run. Yes, I'm accepting reps ! :tup:

You guys keep scaring me...I own an '04.5 Touring Coupe 350Z, and it's been a sweet ride, so far. When I hear the ghastly experiences you're having with your 370s, it's worrysome. Whoa!

The posts you are talking about are from guys beating the snot out of the vehicles on the track. It is not, repeat NOT a problem on the street. :icon14:

Thanks, dude! I was getting worried, hearing those horror stories! Greetings from muggy, rainy Puerto Rico!
