ZF Recommending gearbox oil change at 60k Miles.

51 posts in this topic

ZF state 50-75k for both 6HP boxes and 8HP boxes.

 

Not that servicing my 6HP26 twice within 91,500 miles stopped the Eclutch going...just saying.

Thanks Westy I see the link in your post, and an interesting video. Seems strange to me that BMW don't just offer this service as an option. Surely it would be a nice little earner for them and might avoid problems for owners?

especially now that VAG/Mercedes all offer gearbox services as part of their fixed price servicing program.

It wasn't a risk I was willing to take. I'd stick with the oil that is tried and tested with the ZF box.

I'm thinking of taking my car to a local autobox specialist to have the fluid changed, now the old bus is approaching 200,000 miles (it's been done once before, when the box developed a leak). I'll ask what fluid they plan to put in.

doing a bit of digging apparently shell make ZF's oil 

 

Shell 1375.4 

Interesting as I did a similar exercise a few years ago and was told Esso produced ZF oils!

It will be like BMW and their tie up with engine oil. For years it was Castrol that BMW recommended, now its shell innit?

^well yeah, cos if they fall out with whoever is the flavoured "recommend" oil supplier then they need new oil filler caps...

 

Going back to when my E39 was fixed by Mackie's transmissions in Tollcross Glasgow, I think it was Shell oil that went in, it certainly was not ZF oil printed on the invoice. I can remember that.

Quite possibly - I can't imagine ZF formulating and refining their own. I suspect it's the spec that's the important bit but if you specify 'only genuine ZF oil please' it will hopefully avoid something nasty being used.

I think the main consideration is the preservatives used in the oil. A different oil mix could effectively eat at the clutch plates instead of protecting them.

And that's probably why it's not unheard of for failures to occur not long after an oil change.

Esso LT71141 oil is specified for most ZF 5HP gearboxes (E36, E46, late E39's, etc.)

 

A different set of characteristics are needed for the ZF 6HP gearboxes and that's the Shell 1375.4 oil (badged as ZF Lifeguard 6).

 

The F10/F11 and lots of other makes now use use the ZF 8HP gearbox. That gearbox demands different oil characteristics again and needs ZF Lifeguard 8.

As a sidebar question - is the job of changing the gearbox oil & filter something that really needs to be done by a BMW specialist or would it be within the capabilities of a decent local garage?
