Another Oils Question - Diffs, Gearbox, Trans Box...
Gday. I realise there has been some good discussions on oils on here, but I'm finding it very hard in New Zealand to try and get the exact specified oils.

I'm changing my Diff, Transfer Box and Gearbox oils this weekend and I've bought the following - can anyone tell me if they are ok to use?

Diffs:
Additive: Nulon G70 - PTFE - similar to the Bardahl additive a lot of other forum members use - http://www.nulon.com.au/products/Specialty...wuqsvmSyTM
Oil: Penrite PRO GEAR Full Synthetic 75W-85

Gearbox:
Same additive as above
Oil: Penrite PRO GEAR Full Synthetic 75W-90

Trans box
Same as Gearbox (inc additive)

Are these all OK to use?

The PRO GEAR 75W-90 (Full Syn.) at some repco meets Ford M2C200-C for the gearbox and transfer box
redline gear oil is good apparently also at BNT : http://www.redlineperformance.co.nz/produc...-gear-oil/


castrol 80 90 for diffs
you can get total oils for the engine as well

I recently changed the gearbox oil to the Motul Gear 300 75w90 (full synthetic), and gear changes are now much, much better.

Cheers Mr Naks. I have one question, the owners book specifies it should be Castrol BOT 132. It is an API gl4 and that motul is api gl4 gl5. I had believed it was mandatory to use gl4. Do you reckon any of this? I need to change my gearbox oil soon so if its Censored to keep us buying Castrol Id appreciate to keep postes and give that motul a try! Puma 08 130 HCDCPU

Cheers mate

Mack,

I read up a lot about this on the Oz forum, since their climate/running conditions are very close to what we experience here in ZA.

Basically LR recommends GL4 because GL5 is unsuitable for the yellow metal used in the gearbox (synchro rings). However the Motul (and a few others) are dual rated GL4/5's but are yellow metal safe.

This thread will answer your question: http://www.aulro.com/afvb/90-110-130-defen...300-a.html

Thumbs Up --

Thanks Naks that really cleared it up for me. In my first gearbox oil change I went for the Castrol BOT and now Im up for the second change. I had avoided the syntrax for that gl4/5 issue. Being the BOT almost 3 times the cost I will go for either the syntrax or motul. My driving is moderate. Not much load, I try to keep it below 750 kg when I need to take heavy equipment and it is almost never. I always keep speed less than 80kph. How often do you recommend I change my oil? The dealer recommends every 100k (thats when I did my first change), but now at 50k since first change I wish to do it again.

Cheers
Mack
