brake fluid recommendations

DOT 5.1 is chemically compatible with DOT 4, but it's not ideal to mix them. 5.1 has a lower viscosity specific to ABS systems. The thinner fluid helps the valve response, yet it doesn't provide the same pedal feel as the best DOT 4 fluids.

If you track the car at all, it's worth spending a few extra bucks for a top fluid (like the best, Torque RT700) as you won't have to flush it nearly as often. Some teams I work with are getting 3-4 times the life, a few even more. Their crew is very happy they don't need to flush every day at the track.

If your car rarely sees the track, look for the cheapest fluid with the same specs as the Motul product. After all, it will be the same exact fluid made in the exact same UK factory as theirs is. Only the bottle is different.
