domt101 0 Report post Posted February 9 I know the whole "lifetime fluid" in the transmission isn't correct and as my BMW E39 530i is coming up to 100k miles i want to do gearbox fluid change. Opie Oils suggest the Motul 75w 80 ( https://www.opieoils.co.uk/pv-166225-motul-motyl-gear-sae-75w-80-fully-synthetic-car-gearbox-oil.aspx ) and wanted to know if any has had any experience with this oil? I've heard it might not be great when the gearbox is cold? Any suggestion on the best oil to use/ experience with any manual transmission oils? Share this post Link to post Share on other sites
LukeH 53 Report post Posted February 10 I use Castrol syntrans B 75w in my M3 which I’d say is pretty similar, and that shifts ok when cold, and that gearbox is known for being a little obstinate when temperatures are low. The gearbox oil in my 530d has just hit 200k, so I’m tempted to see what it’s like after that mileage, it still shifts great but it must be well past it’s best by now.

Another one we recommend is the Fuchs Titan Sintofluid 75w-80. Has been very well proven https://www.opieoils.co.uk/p-981-fuchs-titan-sintofluid-sae-75w-80-synthetic-manual-transmission-fluid.aspx Cheers, Guy Share this post Link to post Share on other sites

True, just feel like it's usually a rip off going to the dealers when you can get more or lest the same oil for much less Share this post Link to post Share on other sites
