Why go with non OE fluid? Here are my reasons:

Engine - Lubro-Moly, I like this product's reputation is Europe and the 5L container it comes in reasonably priced at BA.

Transmission - Using OE MTF-LT3, from BA, dealer wouldn't sell me any.

TC - Dealer parts dept. doesn't know what goes in here, using Lubro-Moly ATF 3 from ECS.

Diffs - Dealer says to use OEM (Castrol) SAF-XO, and that they will NOT sell me any. Using Lubro-Moly 75w90 (SAF-XO) from ECS.

Why go with another fluid, . . . because BMW NA policies encourage such creative procurments.

I wish I could have that title but there was some guy from florida that I saw had posted 245,000 or something close. I will pass him in another month or so.

I recently purchased a 2003 X5 with 100k. I decided to ignore the advice of lots of the post on this board and took the advice of an excellent indie shop here in Asheville. He said to change the fluids as lifetime meant 100k. I had all the drive train fluids changed, and yes, including the auto trans. I just cannot buy into the concept of lifetime fluids. I now have 4k on the changes and all is well so far.

yeah, exactly. I just had mine flushed/filled (transfer case) so not sure how you could go 240k miles and not change it once, unless you are refering to the tranny fluid.

... I had mine done at "Insp ll" by my Indie, but I requested that they do the fluids. The dlr is not gonna change out fluids unless you ask and, they may be pricey.
Imo, "Insp II" at a dlr, may be right up there in the high gross margin "service" rung in terms of profit.
