Elf Elfmatic DVI MV

Worth knowing

The introduction and the specification list in this fluid’s data sheet disagree. In the opening line Elf writes that the fluid has DEXRON VI approval, but in the list GM Dexron VI, together with Ford MERCON LV and Ford WSS-M2C938-A, sits under the heading “Meets the requirement of”, that is, as the fluid maker’s own claim; the catalogue follows the list. DEXRON is a licensed GM name, and the data sheet of a licensed fluid gives a licence number next to it. It is that number, not a word in the introduction, that shows whether the fluid is actually licensed. What lies behind each part of the list on an ATF can is unpacked in the article on universal ATFs.

Of the GM and Ford names, the stepped-gear G3 and G3 Syn carry only Dexron III and plain MERCON, and at 100 °C they are thicker: about 7.4 mm²/s against 5.9 mm²/s. No other Elfmatic fluid lists Dexron VI or MERCON LV. Besides, according to Ford, MERCON LV should not go into transmissions that require MERCON V or ULV.
