Had a fluid exchange done a couple years ago on the truck and I'm going to start a yearly pan drop and refill routine. Its spec'd for a very long OCI with the Mercon LV but I just don't trust it. No real issues with the Ford Mercon LV but I do have a 1-2 shift solenoid that sticks once in a while. Since it will only need about 3.5 quarts for each service I am thinking about getting some Amsoil "Fuel Efficient" ATF. They have their Signature Series and their OE lines. Based on price and description the SS is obviously their flagship product with the OE line being marketed as, well, OE replacement. My question is, what would the functional differences of these two be? There is a roughtly 50% price increase going to SS, which is OK, but if its basically the same stuff then I wouldn't want to pay that much more...
Alternatively, I have also considered going with the Maxlife synthetic ATF since it is supposed to be LV compatible and is working great in our Explorer.
