I did a mechanical fluid exchange (15qts) on my car with the old syn M1 MerconV back at 175k. Well my car has 209k and it's time to change the fluid again. This time around I plan on doing drain & fill once I change the oil next week. Will it be ok for me to purchase the Maxlife atf for the drain & fill? Will it mix ok with syn M1 atf? I know that ML makes great oil but I didn't know about the atf. After reading the pdf specs on ML, I see that it's a syn. I would rather purchase that because the M1 aft is more expensive since they changed the bottle and I'm starting to think that I can get a better value with the ML. Thanks!!
