curryinahurry 39 Report post Posted July 15, 2010 Hi, I'm looking at doing my gearbox and diff oil on my 330ci zf 5 speed. I'm wanting to know what oils you've had experience with, whats good and whats not? I've had a quick peek at supercheap auto's, they have a pretty poor selection. I'm going to have a look at BNT tomorrow and see what they have there. Would love to hear from your experience! Cheers, Andrew Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted July 15, 2010 (edited) We use Elf G3LL Longlife full synthetic for the gearbox with new filter & pan gasket for autos Ooops MTF= manual transmission flush ?? If so use G3 Full synthetic ELF 75w90 full synthetic for the diff Edited July 15, 2010 by *Glenn* Quote Share this post Link to post Share on other sites
curryinahurry 39 Report post Posted July 16, 2010 Hi Glenn, Thanks for your reponse. I didn't intend to flush initially, but now that you've mentioned it maybe I should? BNT recommended Fuchs Sintofluid 75w-80 and they also have Redline D4 which seems to be quite popular in the states. I have no idea which ones best.
