Default Anyone using xdrive delete- and lifeguard8 fluid in 2010 535i xdrive?

I'm in Florida so right now I don't need that front wheel drive and I could save a couple gallons of gas per tank. What's the coding I need for xdrive delete? Is it worth it? Also I bought from fcp euro a new auto transmission filter and what I thought was lifeguard6. The car was at the shop getting new bottom end bearings and some other work but it was there for about a month and a half. I just looked in the box and was surprised that i see lifeguard8 not lifeguard6 i must have fat fingered when making my order. I just wanted to swap (think it comes to about 7 liters) it since im now at just over 100k so now what about lifeguard8 instead of lifeguard6. Would I be ok? Internal parts like clutchs gears, etc... or will they let me swap it out? My 04 530i and my 2010 535i xdrive

Don't think the Lifeguard 8 is correct.

Disabling the front drive wheels will not affect gas mileage. There is not a single component in the drivetrain that is not connected to either the front axles or the transfer case, meaning the same rotational mass exists between transfer case open and closed modes. I look at xdelete more as a way of changing the feel of the car or as a way of getting past tx case problems.
