KitTheRam Posted May 22, 2023 Share Posted May 22, 2023 Hello. Thinking about changing the diff oil in my touring as it’s never been done and I hope it may make the car a little smoother - it’s a late 520i diff (running off a 525i engine). I was thinking: https://www.opieoils.co.uk/p-737-castrol-transmax-axle-long-life-75w-90-fully-synthetic-rear-axle-fluid.aspx Any recommendations will be appreciated. Thanks in advance.
