Gearbox oil and general queries.

[madz_6589]

Hey all!

Not new to the Reno game but to the forum.

Gearbox oil, what do I use?
I have been searching high and low for the elf nfj 75w 80, but that doesn't seem to exist here and elf doesn't make it anymore and the replacement is no longer manufactured either.

None of the auto websites here in Australia have a suggested use for Clio specific gearbox oils, all of them come up blank.

I know that Clio gearboxes are known for being temperamental and need a specific type of oil, otherwise it sheers the gears.

Any recommendations?

Also, would love to meet some other clios in NSW

Cheers!

Redline MTL is the oil that works best in a jc5.

 

[JamesBryan]

Red Line oil if you can get it or a high quality GL4 spec oil, not GL5.

 

[hopgop1]

I’m running Millers TRX 75w80 GL5 in mine, smooth changes and no crunching. Although the bottle said GL4 on it also. Not sure if that’s more readily available down under.
I don’t track mine though, hence not splashing out for redline oil.

Good info cheers, due to do mine as well as it goes

How much does the box take/need/do i need to order? And what grade?

Mines going on track and I wasn't sure whether to go for MTL or M90?

 

[R3k1355]

Lots, especially if it leaks like most other JC5 boxes.

There's loads of BS surrounding GL4 and GL5 oil online, it's a real PITA trying to find info. IIRC the MTL is GL4?

@NorthloopCup probably knows the specifics

3 bottles of MTL is enough for the jc5 mate.

If you have a diff, or you do long stints then the MT90 is a better choice because of the heat range it works in.

GL5 is too slippery for the synchros, and whilst it doesn’t kill them instantly, it does take its toll on them.

MTL and MT90 is a GL4 spec oil.

 

[Bankrupt_drunk]

Motul Motylgear 75w-80 EP Technosynthese is GL4 and I think motul specifically recommends it for the JC5 gearbox.

 

[Touring_Rob]

Straight GL5 is a no go, the extra Sulphur/Phosphorus additives attack bronze and copper. I believe things marked GL4/GL5 have different additives which make the oil behave like GL5 but without the additional S/P.

Traditionally GL5 is for diffs, GL4 is for gearboxes.

RED LINE Synthetic Manual Transmission Lubricant MTL 75W-80 GL4
Motul Motylgear 75w-80 EP Technosynthese Car Transmission Fluid

Although not listing compatibility with Renault specifications Fuchs TITAN SINTOFLUID should also be just fine, Red Line would be my go to though if its available.

 

[R3k1355]

Is that still a thing for GL5? I thought they'd come up with newer additives that didn't f**k over yellow metals - considering they're fairly well used.

@NorthloopCup have you ever stripped a box and seen wear to bronze from GL5 oil?

I think they have and that oil is often marked up as GL4/GL5 but redline make a straight GL4 and a GL5 I believe. As Northloop mentioned earlier the slippery GL5 type stuff is a bit too slipely for synchro's regardless of additive compatibility.

I have seen synchro rings that are battered as a result of GL5 oil.

 

[TheBluuu]

i was wondering what oil to be putting in my new refurbed box i put motul in my current one and it worked well untill after 6 months its decided not to

 

[madz_6589]

Cheers everyone!
Good to know everyones perspectives, ended up going with a Penrite semi synthetic 75w 80 that designed for transaxles, transfer cases and manual gearboxes, won't kill the copper and bronze in the gearbox. Finicky things.
Alot of the Reno specific oils you can't get here unless it's a special order from Renault. or elf, even then it can become very difficult to find and expensive very quickly, learnt that the hard way.

Noorthloop cup recommended Redline MTl to me when he rebuilt my box so thats what mines getting, not cheap though.

Is this the correct Motul stuff?
If so, how much does the gearbox take and is this a decent price?

Motul Motylgear 75W-80 Transmission & Differential Oil 1 Litre X3 QTY 3. Quantity (Litres): 1 Litre X3 QTY 3. Stays in 80 viscosity grade after KRL 20 hours shear test as requested by SAE J306 standard.

How often do we get the oil changed? Mine was done in December last year and I'll be booking it in for a service again and was wondering to do it yearly or every 2 years. At the absolute minimum I'll be getting it checked/topped up if needed. Every year felt like overkill but then it is a jc5.

If your I'm England just get the Elf or better yet Redline no? Oli oils stock both.

My logic is that it's at most £50 and takes 20mins to change so I tend to mine each year.

For a road car i'd be ok with every 2 years.

With track use I do every year.
