speedyg 16 Report post Posted March 30, 2006 I am planning to do the diff and gearbox oil this weekend. I have read that Redline is pretty good. What grade do I go for and does anyone know who sells it in Christchurch? Any other oils recommended? The car is a 1989 E30 325i 5 speed and open diff. Thanks Quote Share this post Link to post Share on other sites

speedyg 16 Report post Posted April 2, 2006 Found Redline oil at BNT Automotive on Montreal St. I have done the gearbox but when I went to do the diff I found it has a different size Allen head plug to the gbox. Does anyone know off the top of their head what size it is as I forgot to measure it and want to get one today? I'm guessing around 15mm. Quote Share this post Link to post Share on other sites

Just get a set if you can afford it...especially since you must have the massive g/box key. Quote Share this post Link to post Share on other sites
