Description
Mobil 1 Synthetic ATF is a fully synthetic multi-purpose fluid in the Mobil 1 range for the automatic transmissions of cars, SUVs, vans and light trucks.
It holds no official approvals. The fluid meets Ford MERCON V and JASO 1A; for applications calling for GM Dexron, GM Dexron II, GM Dexron II-D, GM Dexron II-E, GM Dexron III-G, GM Dexron III-H, Ford MERCON, Allison C-4 or Volvo 97340, ExxonMobil recommends it.
Typical figures: 7.4 mm²/s at 100 °C, 36.3 mm²/s at 40 °C, viscosity index 176, pour point -51 °C. The fluid is compatible with mineral ATFs and common seal materials.
Application
Automatic transmissions in cars, SUVs, vans and light trucks where Ford MERCON V is required and, on ExxonMobil's recommendation, older Dexron and MERCON fluids and the Allison C-4 requirement.
Worth knowing
ExxonMobil gives its table of typical properties in a column headed MERCON V, that is, for the specification which the fluid, by the maker’s own statement, “meets or exceeds” together with JASO 1A. Besides the viscosities already mentioned, the table includes Brookfield viscosity: 10,040 mPa·s at -40 °C. The rest of the list, from GM Dexron to Volvo 97340, uses weaker wording: the fluid is merely recommended for applications that call for them. Why Dexron II or plain MERCON on a modern can may be only a claim is explained in the article on long specification lists on universal ATFs.
Neither GM Dexron VI nor GM Dexron HP appears in this list. Mobil Dexron-VI ATF holds the approval for the first, and this fluid’s Mobil 1 line neighbour, Mobil 1 Synthetic LV ATF HP, holds it for the second. Yet neither of them lists Ford MERCON V or JASO 1A. Their viscosity is also lower: 5.85 and 5.7 mm²/s at 100 °C against 7.4 mm²/s for this fluid.
