just been to the gearbox re-con guy, he's been rebuilding boxes for along time and says to use cheap tesco semi-synth 5W 40 to stop the synchro's busting as they need the friction whats that all about!!!

humm was thinking this, he's really knowledgeable about the boxes themselves, and the workshop was good but that statement really did put a doubt in my mind as I was leaving :headno:

 

[Big Bob]

[Dan519]

[Big Bob]

[Mr R.]

Message opie oils, they will know whats best.

Just use the tranself stuff. It says on the bottle specifically for use with renault jc units...

 

[wristel]

Any difference between NFP and NFJ?..

And yes is not the answer I'm looking for..

 

[Lawro]

The NFJ is specifically designed for Renault J series boxes EG. JC5, however the face values are pretty much identical so it won't make any difference. I use NFP 75w-80 and its perfect.

 

[wristel]

so i can go with wither one of the 3?

 

[wristel]

i went for the Motul Motylgear 75W - 80 hope it will do wonders..

Seconded! I used NFP by mistake but have had no troubles whatsoever, and if anything the gear selection is better than before. Maybe Opie Oils (or anyone else in the know) can shed some light on any particular differences between the two!

I though NFP was older and NFJ superseded it.

As someone who has used a multitude of oils in the JC5 box (ATF, 75-90 castrol epx 75/80, gl80 way to thick) in various cars i would just stick the NFJ or NFP it works the best, 3 litres is enough.
