I think its reasonable to recommend 50K fluid changes on all the driveline.
If you want to take it from a mechanics view point and personal preference, I do all my vehicles, my Pa's Defender, my mum's Jeep all at that 50K for driveline and 10K or 6 monthly for engine.

but at the end of the day, I dont force or use any gloom and doom tactics on customers, i throw it out there as an option.

Some of this post is also in the Sticky: Disco 4 Automatic Transmission FAQ - 8 Speed:


I am about to do a second partial flush of my 8 speed at 100k km. I have been provided with the following fluid:

"Auto Fluid, FEBI, ZF 8, 9 Speed Synthetic Fluid, Bilstein includes ATF supplement added to oil"

Has anyone anything to offer on this alternate to Lifeguard 8?
Am I being anal about not wanting to use it when it comes a well respected independent?

I have some Lifeguard 8 left over from my first partial flush & stood it next to the FEBI for comparison. The colour is similar but the smell is different.

Also been supplied some new transfer case oil & have stood the old bottle from the previous change next to the new bottle. Would it be normal for such a variation in colour as shown below?

How old is the older oil? Most likely is that it has oxidized slightly and darkened the colour.
