Good quality gear oil that exceeds GL4 standard.
Comma oil is a reliable brand and this is no exception. I used this GL4 to change the oil in my differentials on my off road Shogun. This is enough to do both front and rear diffs. You will need something to get the oil into the diffs though as this bottle wont allow you to do that. An fluid transfer syringe is the ideal thing and amazon sell them. Saves a lot of struggling under the car. Beware though, this is mineral oil, not synthetic and as such it bloody stinks, it also makes your hands stink and it’s really difficult to get the smell out of your hands or clothes.

Not good for older Land Rovers
Although Amazon/the seller says this is Synthetic, it is Mineral. Amazon also says it’s not correct for a Defender 90, Comma claims it meets the OEM spec. Running it in my Final Drives OK. Transfer Box is another story: During the summer, I noticed my T box was noisy when on longer journeys. Changed for Castrol EP90 (that I found at home) and that fixed it. I don’t recommend this Comma EP oil for older Landies.
