1989 E34 530 - self levelling suspension?

[Mr Nick]

Hi guys, just got myself a 1989 BMW 530 E34, and need to change the PAS oil as it sprung a leak. I cant find out if the car has self levelling suspension or not. I need to know as theres a big difference in the type of oil needed. Its the standard early euro 3 litre straight 6 engine, manual.
Any help would be great.
Cheers.
Nick.
