Idle oil temps of 230-240 ?? Help!

UNKNOWN_370

As far as lsd oil. I keep mine oil with the stock one. Don't change lsd oil unless you intend to buy an aftermarket lsd. Changing oil "may" void warranty on that part. I would go with redline or nissan oem or castrol. All are good. Right now I'm running castrol and am happy. I ran oem nissan oil on my 09 and it was great too. Really either of them are excellent. Royal purple is best to use while out of warranty. It has properties that nissan oem doesn't approve of while under warranty.

Changing the oil in your diff. won't void your warranty. In fact is is a good idea because it's full of metal shavings. Check out some of the related threads on this. Also Redline 75W90 GL-5 gear oil is a full syn while the stock diiff. oil is not.

what?! no the "differential" oil NEEDS to be replaced at around 20-30k miles. it will not void the warranty. heck the dealership changed mine when i had some work done.

I think he means "change to another brand," but either way, will not void warranty, and a very good idea

Yes I meant change from OEM oil. I'll be contacting Nissan to check this out and will get back with a definite answer.

If temps don't drop a bit from redline + k&n filter I'm going to check all pumps and hoses as well as the temp sensor. Next thing would be going with a Z1 or stillen cooler.
Thanks for the help guys!

I had no issues running another brand, provided it meets their spec you are fine

You won't notice temp differences with a different brand oil being that it is the same weight oil. If you drop to 0-40 you should notice a slight difference. Best bet is to get a z1 kit with the thermo adapter. Go with the smaller core size. I have a 34 row and put a full plate on mine with 1/4 in drilled holes and finally have a even temp line of 180-195 highway driving. Just a fyi.
