Autobox oil change, non ZF oil?

[PLuKE]

I am looking for som first hand and long term experience.

I changed my autobox oil in my 330i last year, changing the filter/sump and oil with a genuine ZF kit.

I want to do just an oil change on the autobox of my E61 520d LCI, buying just the genuine ZF oil is rather expensive! I was looking at other oils, but maybe slightly worried that if might/will trash the autobox?

So, any advice chaps? Autobox at present is fine, was looking at preventative maintance.

Thanks

I'm sure that ZF don't make their own oil, they just buy it in from a sub-contracter. You just need to find the specification of the correct oil and buy according to that.

Have you any of the cans you bought for the last oil change? You could find the specification stamped on the label. Otherwise look up a few of the oil finder sites on the 'net.
