Re: What transmission fluid to use for '98 3.8L?

Mobil 1 ATF changed from Mercon to Mercon V AND Mercon last year.
I think that you will see this dual labeling quite a bit as FORD is discontinuing the Mercon as of July of this year.
They issued a TSB stating that vehicles that specify Mercon may use Mercon V, and this is what is to be used in place of the Mercon.
This TSB supercedes the previous TSB's that they had issued saying not to do this.

Anyhow.... As FORD is now saying that Mercon V is the replacement for Mercon......you will see TRUE Mercon V labeled as being for Mercon V and Mercon applications.

Mobile 1 ATF is a quality fluid.....and will serve you well.
Remember to change it every 30K miles (normal service) or 21K miles (severe service).
