correct name for Mercon V

[RF Overlord]

Is it Mercon "Vee" or Mercon "Five"?

If it's "five", then what happened to Mercons I, II, III, and IV?

...and if it's "vee", then what does it stand for?

(No, I don't have anything better to do today...

)

I'm guessing, but perhaps they don't want people to erroneously assume Mercon and Dexron are synonymous... as in the old Dexron/Mercon fluid we're so familiar with. Dexron had a short-lived IV formulation, skipped the V designation for Mercon's sake, and went straight to VI.

Mercon skipped II, III, and IV, and went to V. So yeah, it's five.

Didn't it used to be FLM transmission fluid??

Didn't FLM = Type F?

Anyhow Mercon V is spoken Mercon 5, Roman numeral V.

What the difference between "Mercon" and "Mercon V" ?

 

[wiswind]

abplus, Ford came out with the mercon V specification to address transmission "shudder".
In 2006, they back specifed Mercon V for Mercon applications, which is why most ATF that lists Mercon V on the label will also say that it is for Mercon applications.

The biggest difference is that Mercon V uses a syn or semi syn base oil (probably group III) along with a higher level of friction modifier. The better base oil from what I have heard also is a slight multi viscosity oil (higher viscosity index).

But it is all academic now as Ford has now specified Mercon V to be use in all instances that Mercon was originally specified.
