High Oil Temp - Is this the SOLUTION? (NISSAN'S SUPER OIL)??
 

Living in Texas, we are now nearing summer. It has been 85+ with medium humidity. Naturally one can expect high oil temps however, I realized now, after my first oil change (done by myself) higher oil temps and faster fuel consumption. I drive about 25 miles (1 way) to work 5 days a week, all city streets. Normally, the oil gauge it would stay around 190* with spirited driving. Now, it's going at or slightly above 200+*, same job, same driving habits. I also noticed fuel goes a bit faster too (prior to summer), even driving slower due to high gas prices (I did a re-learing air/Idle). I use only Mobil1 oil, the 2nd change (5/29 @8100 mi), I again used Mobil 1, this time 10/30 extended protection and added a bottle of water wetter. The temp still goes to 200+* even in the morning (78* low humidity 5/31). I began to look at oil coolers and came across this VERY good article (link blow). All 370Z owners should read this article , mainly the part of "Nisan's SUPER OIL" (page 3 & 4 though the whole article is good) After reading this, it seemed to all fit, fuel consumption, high oil temps and it all started after first oil change, so I strongly believe. There is more than just oil Nissan created. It also goes into molecular "bearings" and why this oil is needed for the DLC (diamond hard like coating) on the pistons, cylinder walls etc... Also, it touched on chatter noise on valves and loss of hp due to friction. After reading this article, I plan on switching to NISSAN'S SUPER OIL, Nissan sells it for the same price of a good racing oil, so I'm sold. This oil was crated for the Z's engine. heat is not uncommon in hi out put engines, it touched a little on BMW and Corvette heat issues. YOU GOT TO READ THIS ARTICLE!!!
You have to copy/paste link, stupid thing wont accept a web link, prob because is another forum...? If you're having trouble, PM me, I will email the article link.

You are not talking about Ester Oil, right?



BTW, I went to ZdayZ 2011 put on the car 1,250 miles including the Tail of Dragon and numerous back roads. I didn't have a problem with the oil temp.

The 200 range oil temp is almost standard, if it doesn't goes over 250-260 go will be OK.

So what temps are you hitting? 200+ doesn't help. If you are hitting 200-250 you are okay in that range

please no

In part yes, this has the base of ester oil. Why do you mention this?

I am hitting between 200* - 215*

Your temps are fine. I wouldn't worry until you hit 250+

You are OK!


Because there are so many threads about Ester Oil in here.

Do you use Mobil 1 or something synthetic oil?

So far I only have two free oil change by the dealer. They told me that they used Ester Oil, can't swear on that.

But I haven't had any oil temps problems in almost 2 yrs, I don't DD the Z.

Ok.., I will ask the stupid question (I'm confused)... You're recommending that I should ONLY use Ester oil? I went hunting for tags for Ester oil and it seems everyone is using it with good results. :icon14:

Bottom line to this whole argument. Nissan DOES NOT manufacture oil.

/thread

Strange I just switched to Mobil 1 and I'm feeling the opposite :p (Placebo affect :icon17:)

True. However, they know what the engine needs and their oil has it (see the article) If I'm not mistaken, it basically is ester oil with zinc and other junk formulated for the VQ37VHR.

The ester oil has been shown to be crap. The engine runs 10-15 degrees hotter with it in, and UOA's don't look good at all...

My car overheated in hot weather and on-track with Nissan Ester Oil and with Redline prior to installing my oil cooler. There is no way in hell that NEO is so vastly more lubricating that the engine internal temps are 50F cooler when using it.

96 degrees in dc area for the past 3 days. I have been driving around 25 miles total each day in traffic and open roads.

My temps never got above 200. My car so far has had two oil changes with Nissan Ester Oil.

In January when i bought it new, the oil temp under same driving conditions was around 180. So warmer weather will likely increase the oil temp, but I haven't seen it go over 200 yet..


I don't race or take it on the track so not worried about over-heating or oil cooler.

328i normal oil temps

You are correct. You will never have an oil temp issue if you drive the speed limit and never accelerate hard. But most of us beat the crap out of our Z's once in awhile. Try it you'll like it.

:iagree: drive it like you stole it. Especially under warranty!!!

OP- Please be happy that your temps are staying at or slightly above 200. I live in Dallas and my oil temp is never below 220 by the time I arrive at work. Its usually at 225.

I don't drive hard in the morning and there is very rarely stop and go traffic on my route.

~4500 miles, Nissan Ester

Yeah IMHO unless you drive like a grandma all the time, you need an oil cooler on this car in TX (and a quality synthetic). I highly recommend one with a thermostatic sandwich plate though. If you're not even hitting 220+ don't worry, but I think you'll find if you really push the car (especially any kind of track scenario) in the summer, 250+ is easy to find, and limp mode isn't far away at that point.

Yes. TX is awesome in the summer. I see 220-230 if I get accel happy. Lately, it has been 90+ degrees F and the Fairlady is not happy, lol..........

Mobil 1 Synth is your friend BTW. She will like it. Miine gets Mobile 1 normally, but the dealer used Valvoline for some reason this time. So yeah, she is kinda tempermental at the moment..........

Yea try it you like it LOL.., oh yea! you bought a sports car, you pay the sports car insurance, get Trurnt'! :excited:

By the way, this morning (and yesterday) it was 71* no humidity, oil temp stayed at 195*. On the way home it was 91* and hazy, I rolled the windows down, raced everyone, I drifted corners and keep a sharp eye on my radar detector, she stayed just below 220*. I just checked the oil level, its still at the "H" so, I guess I shouldn't worry and chill.

Love to see people enjoying their cars. Nothing worse than a beatifull car parked in someones garage.You are right, it is indeed a true sports car.

From what I hear the ester in the oil is actually used to protect the seals. I plan on using Motul since I know a good garage that carries it.

I ran the Ester for the first 10k on my car and switched to Pennzoil Ultra Syn for the last 10k. I saw no diff's in performance or oil temps personally. In 80+ degree weather, mine usually hovers around 210-220 in city traffic.

I've hit 240-250 on Dealers oil changes doing a few miles of very spirited driving. Not very happy about that since my Old 350Z never had that problem.

Be careful with how close you run to that H-mark. L<->H on the dipstick is a range. H is not the target. The ideal is somewhere in the middle (I usually shoot for about 2/3 up between L and H), and it's the holes rather than the letters that indicate the range marks. Check while parked on a perfectly level surface with the engine off for at least 10 minutes. If you end up overfilled, your oil will foam and not lubricate/cool as well.

Unless you have an oil cooler with bottom or side hoses, in which case you have to take oil back flow into consideration.

Damn you, I got quoted while editing :) How do you guys with side/bottom cooler hoses guestimate that? Mine are top connections.

Haha, no ninja edit for you. I check the oil immediately after shutting the engine down and shoot for a reading between the Low and Mid marks. Mine is a side mount so it doesn't back flow completely but it is a measurable amount.

Ahh.., yes you are correct, thanks! Per the manual, it calls for w/oil filter change 5-1/8 quarts, I put 5 quarts even. The oil sits just near the "high" dip stick hole. I was just speaking in general, my dad taught me long ago about the no-no's of over filling.

FYI - Though were not (officially) in summer, it's been very hot this week, I am happy to say, I drive spirited (when safely possible) and my oil temps, even with a/c blowing at times, has not gone over 210*. Gillian is all good! :driving:
