For those who frequent the site, you may have seen my ongoing thread in this forum about my efforts to improve performance from the 6F35 unit in our Fusion. Last week I did a drain/fill with 4 quarts of Redline D6, and 1 quart of Maxlife ATF (didn't have enough D6). Once I drive the car enough to judge the new performance, I'll post about it. But I got to thinking something...
The 6F35 was, in large part, a joint venture project between GM and Ford. Now, I don't know how much or what is different about the actual GM and Ford units, but I do know that they are very similar. I also know that there are far fewer complaints about the GM unit. Which got me to thinking: maybe the reason for this is because GM's Dexron VI fluid is superior to Ford's Mercon LV? Licensed and approved Dexron VI is readily available and easy to find by a number of different brands, whereas Mercon LV still has no officially licensed aftermarket counterpart, and is for the most part a dealer-only item.
Just thinking out loud here. I realize that licensing and approvals usually mean nothing; maybe Ford didn't feel the need to certify other brands to meet their fluid's specs. Who knows. I wonder how Dex VI would perform in the 6F35, though. Mercon LV and Dex VI have very similar, in fact nearly identical viscosities at 40 C and 100 C. Albeit, the additive packages are different in both fluids. The Redline D6 I put in the Fusion last week is basically Redline's version of Dex VI, which also had product crossover to Mercon LV applications. Anyone tried licensed Dex VI fluid in their Ford, or more specifically, a 6F35 unit?
