I've had Amsoil Synthetic ATF in my Explorer LTD since the first change. My mechanic uses nothing else. He has used it in everything he owns plus customer's vehicles including commercials.
I did a lot of research and spoke to a number of fluid engineers at different companies and they all said the BMW Lifetime, ooops sorry, 100K fluid change was baloney.
