BMW Oil and Filter Change – Late Model V8, N62 – 745Li, 545i, 645Ci, 750i, 550i, 650Ci, X5, etc.

Q I would like to know what kind of special tools I need to change the oil and filter on a 2002 745i. Today I went to two different oil changing places and was told they didn’t have the correct tools to do my Bimmer. I always changed the oil in my 2000 328i myself and would like to do the same for my 745i. Can you help me figure it out? Thanks.

A The oil filter on your 745i is a bit different from your 328i. It is located on the bottom of the engine. It actually mounts through the oil pan, but this is not a big deal. The filter is housed inside a canister cup, similar to your 328i. And the canister cup unscrews just as the canister cover does on your 328i, but from the bottom. There is a drain plug in the bottom of the canister cup. Using a 5mm Allen tool, remove the plug to drain the oil from the cup before unscrewing it. (Don’t worry – the housing area for the cup is sealed off from the oil in the pan, so you won’t drain the entire pan when you remove the filter, just the oil in the cup.) Once the plug is removed from the canister cup and the oil is drained, just unscrew the cup and remove the filter. The oil pan itself drains just like the one on your 328i.

    On my 2002 X5 does the oil drain plug require 5.5mm Allen tool?

    • Note that the V8 models mentioned in the initial blog post are of the N62 engine family. Your 2002 X5 will have either the M54 6-cylinder (3.0 liter) or the M62 V8 (4.4 liter). Both of these engines are different from the N62 V8 in the original post.

      If your X5 has the 3.0 liter 6-cylinder, the drain plug has a 13mm hex head (use a standard socket or box-end wrench).

      If you have the 4.4 liter V8, the drain plug has a 17mm hex head.
