After how much time, or how many miles should one change their differential fluid (in a 1st gen LS400)?
Thank you

Check your owners manual. It will be listed there. But I believe it's every 30k miles, at least that's what it was for my old GS400.

well, here's the deal: It's a '91 model and the last time it was changed was in '95, when the car had around 40000 miles on it. Now it has 74000 miles on it and, of course, we're in the year 2003. So is time factor more important or the mileage? (it's probably better to do it now anyway, it's been 30000 miles already).
Thanks guys.
