question bout engine oil

[gtrte37]

doing my first oil change since I bought my GTR. asked the previous owner what he put, he said 15W50 motul. I was thinkin it was too thick, but i also cant find 15w50 anywhere, and i thought the 300zx tt oil filter would fit, but its too big, also fitted with oil cooler and relocated, I could go to the owner but he charges $45 for 2 litres and the car needs 5.5L. any suggestions?

not sure about a gtr but a gts the oil filter i use is from a s13 240sx and 45$ FOR 2 LITRES holy **** overpriced much?

[gtrjon]

what relocation kit do you have? my grex kit i used a s13 filter (91 nissan 240sx.) also i run 10w40 royal purple in my r32! 15w50 is kinda thick but if you wana run it im sure some of the sponsers on here could help you out. throw braden at jns imports a pm.

i use 300zx tt on my gts. no issues. odd.

[gtrte37]

im pretty sure its a trust relocation kit, does bradon @jns imports have hook ups in vancouver? cuase hes in alberta

I have the Trust/Grex relocation kit and use 95-97 240sx filter, fits like a charm.

[gtrte37]

thanks man ill try it out, what type of oil do you use?

[Manny-u*nit]

15w50 motul is what i run on my dirtbike...

Nismo competition oil for RB26DETT is 15w50....

and I believe its made by MOTUL as well

Look at oil temp gauge and cst rating of oil to choose correct oil. Look at Opie Oil (oil experts) 10w60 PDF, as they explain how to choose the correct oil based on looking at oiltemp for your engine, cst rating -

http://www.opieoils.co.uk/pdfs/tech-articles/10w-60-oil.pdf

Most can get away with 10W40, as is good for 100-120 degrees that most Skylines run at on the motorway (RB20DET in my car ran 5w30 at factory and they mention cst rating for 30 at 100 degrees in above link). w50 is racetrack use where your oiltemps are constantly at 100-120. Just intake, exhaust on RB20DET without engine oilcooler sits around 93 degrees after a drive on the street. Also I think that's degrees celcius (UK, Canada, etc), not degrees fahrenheit (US, etc)

The first number is cold start and 5-10 is what most Skylines run.

I ran 10W60 that was recommended and found out it was the cause of rough running engine (engine fighting to idle because oil was too thick), noisy lifters, less responsive engine, etc. Switched to 10W40 and solved those problems and starts better when cold. Wouldn't think oil makes that much difference, but it does.

Trust/Greddy uses Toyota AE86 filter and it is the same thread as Nissan, the OD is smaller but the seat (seal) diameter may be small enough to work as Micho have suggested. 92 Camry filter will work too if you can't find AE86 filter.

clearly, you've never bought Motul 300V before..

[evilgtr]

Love the Motul 300V I picked some up from Cam at lightspeed , i did alot of research on the 300v and its amazing ! the tests that they put the oil through are second to none. If it will handle the 24hours of lemans with 0 viscosity breakdown it will handle the daily driving of my gtr with ease

it is costly though, I am running 10w40

[bobbo]

There is no way you'll need to run 15w50 for street use. The manual says 7.5w30 so you can use obviously 5 or 10w30 for street use.
Under extreme conditions some use 10w50 which will give you additional oil pressure.

10w30 Mobil1 is what i use for daily driving...more than sufficient.
