I haven’t used the Penrite oil, but have been using Motul Gear 300 75-90 for the last 150,000km (change every 40k) without issue. Gear changes are nice and smooth… for a Defender.

						SupporterPlanning to change my oils ……gear box transfer case and diffs
…specs mostly GL4 and GL5 which I can get from Penrite
the gearbox oil specified as Castrol BOT 130M …or equivalent….
This seems to be very hard to find so Penrite have a gearbox oil they recommend for defenders
anyone used the Penrite gearbox oil and does it do the job safely ?…..don’t want to make an expensive mistake so thoughts much appreciated

Mechanic told me penrite transgear was the best fit for r380 and lt230 in Aus
75w-80 for r380
75w-90 for lt230

						Its been two weeks so you've probably bought the Penrite but for what it is worth.
After much procrastination, for my MT82 I settled on Castrol Syntrans 75-85 its a full synth GL4 spec oil
Have now ticked over 7 years and into the third change of oil. No shifting issues seems to be doing the job.

						SupporterWhat does r380 and it230 mean
I have a defender 110 puma 2.2 2016
the handbook specs call for a GL4 Or. a GL5 in the transfer …..and the Castro BOT 130 m in the gearbox ……..
I’m leaning to the Penrite 75W90 GL4 for the gearbox
and 75W90 GL 5/6 for the transfer case
did see on one video that should use GL4 rather than GL 5 in the transfer box which seems contrary to the hand book specs So I’m a bit confused

						The R380 is the 5 speed manual gearbox used in Defenders from mid 90s to 2006??, and Disco 1 and 2
The LT230 is the transfer case used with all the 5 and 6 speed gearboxes in the Defender and all Disco 1 and 2s.
Your Defender 110 Puma 2.2 has a MT82 gearbox and a LT230 transfer case.

						SupporterI'm using the penrite oils in my puma.
The ProGear GL4 75-90 in the gearbox and the ProGear 75-90 in the trans case.
The name of the latter doesn't include it's GL rating but it is GL5.
For the MT82 gearbox, the requirement is the Ford WSD-M2C200-2 spec, which the ProGear GL4 meets.
The service schedule shows gearbox oil change every 200,000km, but I've been doing 80k to align with the diff/t'case oils. Might go down to 40k intervals for box and diffs as it gets older!
