Valvoline Mercon V

[Bob Ayers]

I flushed my tanny today, and changed the filter. I only use Mercon V, non of the multi-purpose (Dex & Mercon) ATFs. I have heard good things about the Valvoline full synthetic Mercon V, and it looks like all of Valvoline's Mercon V are full synthetic. You can see from these photos, that the Valvoline Mercon V (not labeled full synthetic) is the same part number as the Valvoline Mercon V which is (labeled "Full Synthetic). The last time I flushed my tranny, I used Castrol Mercon V, which is a synthetic blend, just like Motorcraft Mercon V:

I don't think the Valvoline is full synthetic anymore. Their product data sheets have changed early this year, indicating they remformulated the fluid. Also, I really don't think Valvoline would not advertise it being a full synthetic if they could, especially when they wouldn't even have to change the label.

I emailed Valvoline about this, asking if the product was still full syn, and they never responded to me. After a few days, I emailed them once more, using a different name and email address, so they wouldn't think I was the same pesky customer. They still never responded to me. I've emailed them before in the past about other products and they were always quick to respond, usually within the 1/2 hour. Not this time. It's pretty fishy.

I made a thread about this about 2 months ago on bobistheoilguy.com which you can view here.
