Read several articles on which is the correct transmission fluid to use. Owners manual & transmission sticker states Mercon syn and now since mercon has changed to mercon V to use that. A local mechanic said to use any full syn and if the trans chatters to use mobile 1 LV. All the reading Ive seen states to use only motocraft mercon V. What do I use? I do have some dextrose III/mercon in my shop thats available. Looking for some advice. Thanks
Welcome to FTE. An old adage that applies here: "When in doubt, read the book". I would go with what your manual says to use. It is probably what has been in there since new anyway!
Mercon LV replaced all applications requiring Mercon SP, not Mercon V. I wouldn't use LV ( Low Viscosity) in any application that doesn't specifically call for a low viscosity fluid.
Mercon V is still available from many different vendors.
