Gearbox oil (Royal Purple)

[Diesel_Power]

Looking to order some engine & gearbox oil as the service is quite close now, decided to go with Royal Purple engine and gearbox oil:

Engine (5w-40 5.6 Litres):

Gearbox (75w-90 3.7 Litres):

Anyone had any experiences with these oils? Heard nothing but good things.

Edde has, Ben p and others..

It's supposed to be the best.. i could'nt get it in Holland so i stuck with the ELF TRX 75w80, recommended oil by Reno and less than half the price of this Royal stuff.

go for it though

I got it for mine. It made the syncros stick and the gears grind because of this. The box was more clunky than stock and horrible when cold. I would stick to the oil grade recomended by Renault. Gear change is 100 times better since I removed the Royal Purple. Worst £60 ive ever spent!!!

Apart from that its brilliant!!!

Oh no doubt its good oil, but you MUST use the grade specified when it comes to renault cheese boxes. If they did a gearbox lube in 75/80 GL5 I wouldn't hesitate.

Yeah against my wallets best interests the oil came out. The box is like new now it has the recomended grade in it.

Sorry pal I wasnt taking the piss, at the end of the day you could have taken it to a garage and would have cost you a hell of a lot more so not to bad all in all!

Didn't think you were taking the piss!!! I was just reluctant to remove the oil as it cost so much even though deep down I knew it ws the right thing to do!!!!

the royal purple stuff is the best out there,

what grade did you run. maybe thats what caused you issues?

ive just bought this to try

http://www.opieoils.co.uk/p-981-fuc...w-80-synthetic-manual-transmission-fluid.aspx

its fully synthetic GL5

the castrol stuff is mineral (sp) iirc so this stuff owns!

 

[mattjk]

Fair enough! When it comes to gearboxes I dont think it matters as much as having a FS engine oil

Caister: Thats understandable matey, What did you do with the old stuff? I mean it probably hadnt had a chance to break down at all I would have put it back in the tub and sold it back on for some beer tokens

I'd always stick with the proper viscosity with the renault boxes, it needs all the help it can get. The castrol stuff isn't bad tbh i've used in the my old 1.6 and the 172 and its always been an improvement.

The fuchs stuff is probably worth a try though, I almost ordered that instead of the castrol but stuck with what I knew.
