Which oils to use? - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Jim27 · 6th July 2006, 08:08 AM

I'm going to get the fluids changed in my R32 and need some advice on what to refill everything with.

It's running standard drivetrain, twin-plate clutch and an R33 engine with 34,000 miles under it's belt, FSH. 90% of the time it runs at 0.8 bar, but is mapped up to a smidge under 500bhp (450lb/ft torque) at 1.3bar. Gearbox is fine apart from the usual crunch when going into 4th under heavy load. I've also noticed when <ahem> "giving it some" that rapid changes from 1 to 2 then banging it into 3 I am unable to go straight into 3rd - feels like it's catching on the gate and I have to release pressure on the gearknob and then push it in again.

I'm thinking I should change both diffs, gearbox and engine oil.

That's in in a nutshell

So what oils should I use? I've been reading that maybe I should try Redline Shockproof for the gearbox - but which one?

Any help/advice much appreciated guys (and gals

).

Edited to say that I HAVE used the search facility but there's soo much differing opinion/info that I thought maybe it'd help to try and pull it all together on one thread...?

Oops - forgot the transfer box as well

I just put some good synthetic in and it was much better, didn't bother with redline, more of a drag/race spec.

Ask RK what it was.

I got all Motul fluids delivered by Opie for £90, gearbox, transfer box, front and rear diff.

Car is running so much smoother now, even the cold crunch from 1st to 2nd has gone.

Have had a chat to Opie - very helpful guys

Will be ordering my oils from them when I've sorted some pennies out

I have just bought 4 litres of syltran or something like that for the gear box. Putting it in next week and will post what (if any) difference it makes.

oils are fecking expensive though thats for sure!

True but I look at it like this - even though buying the pukka stuff is expensive, I'm an ignorant noodle when it comes to oils. So if paying a bit more for some spot-on oil means that I get some seriously quality advice like I received from Opie Oils then I'm happy to do just that

I am the same, especially with transmission oils. I had a few emails with him and he recommended the silktran which I have ordered.

Oils are CHEAP considering they are the first line of defence!

Always remember that you will spend more in a month on petrol than you will spend on a whole years oil and that's the good stuff.

Cheers

PS. It's SILKOLENE SILKTRAN SYN 5 75w-90 top stuff!
