Liqui Moly Top Tec ATF 1100 G

Worth knowing

Only two fluids in the catalogue carry the approval number ZF004926: this one and the red Top Tec ATF 1100. Their code lists also match, apart from one line: DTFR 13C100 H, a commercial-vehicle code linked to the MB 236.1 sheet, is absent from this fluid’s data sheet. If the vehicle documentation names the DTFR code specifically, of these two only the red fluid’s data sheet confirms it, whereas MB 236.1 is listed as an approval for both.

A shared number does not mean identical figures: 34.1 against 36 mm²/s at 40 °C, viscosity index 192 against 180, pour point -45 against -48 °C, flash point 212 against 220 °C. The data sheets give shear stability over different periods, 20 and 100 h, so 5.1 and 5.4 mm²/s cannot be compared directly. They also describe the base differently: “synthetic HC base oils” here, “synthetic technology” for the red one. The article on the word “synthetic” on the label shows what lies behind such wording and why the approval matters more than the wording. One caveat is shared: both data sheets promise optimum performance only when the fluid is not mixed.
