I have a 2012 bmw 528xi f10 need front and rear diff fluid can I use this for both front and back or just front ?
Answer (Posted by FCP Euro Products Team)
Yes, this fluid can be used however this kit is only applicable to the front differential. The rear diff only has a fill plug for checking the fluid level. Since there is no easy way to empty the fluid from the rear diff we do not offer a service kit.

I have a 2008 3.0xdrive, the description says this one is for the front diff, can I also use this for the rear diff? Same drain plug? Thanks

This kit is only applicable to the front differential. The rear diff only has a fill plug for checking the fluid level. Since there is no easy way to empty the fluid from the rear diff we do not offer a service kit. However, its fill is approximately 1.5 liters of 75W90.

I have a 2015 F30 328i X-Drive and just watched FCP's DIY video "How To Replace BMW F30 Front Differential Fluid" (https://blog.fcpeuro.com/how-to-replace-bmw-f30-front-differential-fluid-bmw-xdrive), and at 30 seconds into the video, it is explained that the BMW Hypoid Axle Oil G2: "...is the only gear oil currently on the market that is compatible with front the differential. BMW has moved to these lower viscosity gear oils to help reduce fuel consumption, so unfortunately a traditional 75W-90 is not going to be the best option to go with." My question is, will Liqui Moly GL5 75W-90 cause damage or exacerbate wear in some way to the front differential that would be avoided by using the BMW Hypoid G2, or is the requirement for the BMW Hypoid G2 primarily due to lower fuel consumption?

No, it will not cause damage or cause extra wear to the front differential. The requirement for the BMW Hypoid G2 oil is primarily for lower fuel consumption.

1 liter is needed for each differential. The drain plugs will be the same.

How many bottles would I need for a 2015 320 xdrive?
Answer (Posted by FCP Euro Products Team)
This is a front differential service kit only. The rear diff for your year/model only has a fill plug making it impossible to drain and fill unless the cover is physically removed. You can generally remove 1 liter (give or take) of fluid from the rear diff with a siphon. The rear differential typically holds 1.7 liters of oil in total.

2015 435i X-Drive I see the kit is for the front differential, couldn’t you fill and flush out the rear diff with it too? Considering it’s the same fluid required
Answer (Posted by FCP Euro Products Team)
The rear differential does not have a drain plug. Because of this we do not offer service kits. Your option for the rear differential is either to remove the cover or attempt to siphon as much out as possible. Also you will need x2 liters for the rear differential.
