CastrolTransmax AXLE Long Life 75W-90 1L

This is a very good oil, and of course excellent service from Amazon too. Especially good is next day Prime, on these kind of items, when you want goods such as this, you would like it ASAP. Prime is great for this. Thank you Amazon!

This oil is the recommended lubricant for the rear differential unit on a 2002 BMW 316ti Compact E46 model. I have used Castrol lubricants for several decades and have never had any problems. There’s not a lot to say other than it’s a premium brand, it’s runny, oily and lubricates the gears in the rear differential unit. It smells nice too but I wouldn’t really want to cover myself in it.

Used this for a my Audi TT 225 Quattro only use quality oil and this definitely is the perfect oil gor this car

Perfect for the servicing of the rear drive on BMW motorcycles (with shaft drive).

It's Castrol, it's oil, it's just what they do

Definitely long lasting as i only need 200ml in my final drive (BMW 1200 ADV - 2011).Only 4 stars because the flipping tube built into the cap doesn't fit the filler hole on the FD of this bike - so you either have to get a dedicated syringe (basting/roasting syringes are good, but another thing to buy and mess around with) OR do as i did and pinch the cap of a different brand of gear oil with a tube that does fit. I didn't spill a drop.I marked out the bottle carefully before doing this. I also change the FD oil once a year, so in theory 1ltr will do 5 years - in theory! So £3.60 per oil change. Has to be worth it.This is a high spec oil so one worry off the list.

Purchased for the final drive on my BMW motorbike. Have used it previously and never had any reason to doubt the quality. Goes in clean, comes out clean so it's doing its job.

Its a recommended oil by manufacturer which can't be usually replaced with something else unless expert in the area. Happy with it as the car did not complaint more than a month now.
