Oil Temp
I know it varies with outside temp and driving style. But today only got up to 78 degrees, I was doing mild spirited driving and my oil temp got up to 230 VERY quickly... I don't think I have ever seen it that high and it isn't even summer where days are 95-98 easily. Could I need a bigger oil cooler due to having a tune? Open to recommendations....want to get a handle on this before Floridas sun starts blazing! Thanks in advance!

Check your coolant and oil level when ur car is cold.

Forgot to mention to make sure that u checked the engine cap not just the coolant reservoir, now grab a flash light and shine it on your front grill to make sure that there are no bags, debris, or W/e restricting the air flow through the the radiator, if all clean, the next thing is OB codes to check. If nothing continue to monitor your oil temp.

A oil cooler is always a good idea specially in hot areas such as Florida ...and you mentioned you got a tune ..you could have them make your fans come on sooner as well ....with both of those things done you will be good to go with any temp.

I see 240+ oil temps routinely just driving on the highway in the summer heat here in Texas (80+ mph speed limits). But with an oil cooler, I would expect to have some difficulty warming up the car on my short, daily drive into the office even during the summer.
Keeping the Z cool is a difficult proposition when driving hard. I've got a 34 row oil cooler waiting in the garage for when the Z is no longer my daily (hopefully this year). But for a daily driver, I just didn't see the need. And frankly, reaching higher temps quickly is good incentive to back off after some brief fun on public roads - better to keep the serious driving for a closed course. |
I was wot 2nd gear/3rd on the dragon. I did hit 260 briefly on the hottest run. Of the 4 runs I averaged about 230. Wasn't too concerned about temps.
You should be fine. As jar said warm up will take a lot longer. I was considering the smaller stillen one but in Cooler months it might prove issues. It feels good to pass people on the dragon lol |

I agree with 2011 Nismo#91 (other than changing the oil vis thing). Most modern motor oils are rated to 300F and the nannies will protect the engine. As long as the temp is spiking only under a hard load with "high" ambient temps, you are OK. Back off for a while and temps should return to normal after a few minutes. If temps don't drop back to normal after 5-10 minutes of "normal" driving (at speeds above 30 mph or so to keep air moving across the radiator), then you may have a problem.
As for changing the oil viscosity, not necessary (at least for a DD). It won't really hurt but won't it won't accomplish much, either. YMMV |
My gamma oil pan keeps my temps pretty well in check in the FL heat, even with intercoolers blocking my radiator and no additional cooling mods. Another member asked me to do a test at around 75 degrees... at 77 degrees, I did some spirited driving including 4 full boost runs up to about 140 and my oil temps didn't pass 215.
I also deleted the OEM oil cooler... the only difference I can see is that it takes about 30 additional seconds on my morning commute for the temp needle to lift off of the stop... no observable impact to max temperature. |
Oil Temps
Z-Girl, the factory oil cooler (and radiator) cooling fins can get clogged with bugs etc. I cleaned mine recently with a nylon brush. I don't see those kinds of temps unless pushing it hard.
BTW....Mobil 1 says, their oil is good to 300 degrees. I wouldn't push it to that, but that's what info says. |
Order an Fast Intentions oil cooler kit for your car. Your issue will be resolved.

I guess the BP oil cooler set up works pretty good because I have'nt been over 210 since I had my turbo and the 210 was repeated full boost runs. I average 198-205 here in Orlando .

I don't live in a really warm area, but tuning the radiator fan makes a remarkable difference in recovery. I wouldn't lean on it to actually fight temperature build up, but it could be the difference of taking it easy vs. straight up pulling over to let the engine cool down.

Z1 will tune tomorrow to set fans to turn on earlier. Will give that a shot for a week. Next week we should see 80degrees. If tune does nothing i will order their oil cooler.
Thanks guys! |
The VQ Engine typically disperses almost all of the oil out of the pan into the engine on WOT, heating up the oil quickly as a result. So even though your spirited driving may not be as hard, once you hit the pedal down hard a couple/three times the temps will jump up fairly quickly.
I installed a 9 row Stillen Oil Cooler, but failed to get a thermostatically controlled adapter plate - so in the winter time at and below 40°F, it is difficult to get the oil temps up to at least 180°F, which is bad as the water vapor from the internal combustion reaction will contaminate the oil. So, I installed an aluminum plate over 6 of the rows on the cooler, and left 3 rows uncovered. For Louisiana weather, and someone who does not track their Z, this proved to be perfect. In the summer time, the temps at Spirited Driving climb and hover around the 230°F mark and come down fairly quickly to 220°F and hover between 210°F and 220°F consistently under normal driving. My advice is get a small oil cooler if you're not going to track the car or a large one if you are - that is, if oil temps are an issue for you. Either way, make sure you specify a thermostatically controlled adapter plate that will only open and divert the oil into the cooler when the oil temp reaches 180°F. That will make life a lot nicer for you and the car in the freezing winter months. |
