This 1995 318i is my first Bmw and wanting to do some easy first-time maintenance I thought I'd change the oil. I ended up draining out about 20oz. of atf before I could get the plug back in! Can I top it off with RedlineD4ATF? Should I drain it entirely then replace it with Redline? Or should I just use fluid from the dealer. Is the 1995 car filled with lifetime fluid? Btw, what type of oil and filter do you recommend for this car. Thanks, Jim
