Can someone please tell me how much transmission fluid I will need to do a flush on my 1989 300CE?
Also, what brand is recommended? Here is what the local store carries:
1. Mobil 1 $8.99 Canadian /quart

Not the Supersyn pictured below

2. Amsoil $11.99 Canadian /quart

3. Castrol ATF $3.99 Canadian /quart
Here is a site comparing Amsoil to Mobil 1:
