In another link you stated, "the low viscosity of Mercon SP isn't ideal for anything other than minimal commuting. " http://www.e90post.com/forums/showthread.php?t=363648
If you had the choice of Castrol Import Multi-vehicle (which is the oil that I used in this DIY), Lifeguard, or Mercon SP, wouldn't you use the Castrol oil over the other two? Note: In that same thread you stated, "The only multi spec ATF I mentioned was castrol's. Its just fine in our transmission. I love its KV 100C of 8! Not bad for mineral oil based stuff! Won't hurt our trans, and its bound to have better thermal stability that LG6."
