What oil to use in RB25DE?

[Greg]

hi all,

I'm about to do my first oil change since compliance and since i don't have an owner's manual i was wondering if someone out there would be kind enough to post up what type of oil i should be using (ie weight etc). Is it the same as the RB25DET?

Thanks,

Greg

on my petrol cap, there was a mobil one sticker, so i used that.

but at the moment, shell fully synthetic is in.

Rb25de likes to rev hard, so i wouldnt used anything less then synthetic, but semi syntheic would be okay i guess

I'm lazy - I always take my car to my local Nissan dealer (one that tends to deal mainly in Skylines, 180Sx's etc) and get them to change the oil - don't know what type, but whatever it is, it must be OK for the car...

I use motul, seems lots of import users use that, ppl say its better then shell helix, bloody expensive though but worth it for ur baby fully synthetic of course. i think the rating is 5w40 or sumthin. so it starts easy and remains the same throughout the rev range. its doin well cos i was on the track yesterday doin laps and the only thing that overheated in my car was the CAT, i think i destroyed the stuff inside it which means POLLUTION (oh well)

I just serviced my baby, i used Motul 8100 Synergie 100% Synth.

It holds it temp great, and it seems to let the revs flow a little more free, warms up nice an quick too.

Just got a call from repco too, my new iridium plugs are in, ill let you guys know how they perform.

good work Ryan D

How much did the products cost ya mate?

[Ryan D]

Motul 8100 Synth - $55 from Autobarn (UAS wanted 65)

NGK Iridium Sparks - $13.50 each

Ryco Fuel Filter

Ryco Oil Filter - $9

Nulon Radiator Fluid *Make sure you definately check your coolant levels*

My car seems to run better milage with the ryco filter, and the oil holds better, prolly due to oil quality, UAS said the genuine nissan oil filters are better and arnt that much more expensive ~$13

Try and get a 100% synth oil no matter what, they warm up quicker and can move more freely around the vital areas.

back from the dead...

so we've established that a fully synthetic oil should be used, but what weight/thickness should be used? i believe it should be heavier/thicker than the oil in a RB25DET, which people on this forum generally agree should be 5w40, but i can't find any info on the RB25DE.

i've just done my first 5000kms so i need to change pretty soon.

has anyone got a workshop manual that states what oil nissan recommends?

Cheers,

Greg

check the brand sites like shell mobil etc..they usally have some type of guide on what oil to use on specific cars.

thanks mate

5w-40w

the 5w is the thickness of when the car is cold and starts up..so having a thick old for startup dosent really help at all to lubricate the engine when its cold and causes more wear on startup from cold. the 40w rating is the highest temp or how thin it can get and the high temps.

The only oils i would consider is 5w-40w maybe 5w-50w...10-40w and maybe 5w-30w also...nissan dealers have the original oil which is 7.5-30w which has a nice gtr logo on it.

[Guest RedLineGTR]

Not being a smartarse or anything dont know if you have read any of the old thread..some good info to look at. Most brand people use are shell,mobil,motul,castrol,redline...etc..

[Greg]

thanks for explaining it all, i had a vague kind of idea that the numbers were idicating viscosity but didnt really know what that meant

the mobil site recommended Mobil 1 5W-50 for an RB30 (they didn't have RB25) and that sounds about right from what you and others have said. i'll look into the motul because a lot of people seem to be using it. me being a tightarse, it will probably come down to price when deciding between mobil1 and motul. anyway thanks for your help.

cheers

ive just put shell helix ultra 5w-40, ive made out in the maual that they reccomend 7w-40, sumthing not very common in auto shops here! im thinking of putting 10w 40 in next time just to see if there are any differences. i thinking opf using mobil R next time round, its what they use in dads M3

Where can you get the owner's manual from anyway? I really need one of these ey.

Try Ebay search for skylines in the cars section. There is usually some manuals available
