Okay so I acquired an e39 530i from my father about 6 months ago and have been going through all the fluids on the vehicle progressively. It's about time to do the transmission and I'm up torn between lifeguard 5, Pentosin ATF1 and either Amsoil SS or OE ATF.
I've read a bunch of threads saying using anything buy lifeguard 5 or ATF1 will shorten service life, which I could live with knowing I have fresher fluid every 30-50k miles. The car currently has about 165k on it, looking to keep this car a good while.
Any input is great.
Thanks - Sam
