    Fully Synthetic. The Red Line 75w140 Fully Synthetic Gear Oil is a great oil for your daily driven performance Mustang. Red Line's formula is formed from polyol ester base stocks and friction modifiers that provide exceptional lubrication. In turn, this helps to decrease operating temperatures by reducing the sliding friction of the hypoid gears.

    Contains Friction Modifier. Unlike other brands of gear oil, Red Line's formulation contains friction modifiers suitable for use with clutch or cone type limited slip differentials - for most LSDs applications, no additional friction modifiers are required.

    Superior Protection. Red Line synthetic gear oil features a high natural viscosity index (VI) for a relatively constant viscosity and film thickness that coats all differential components to provide excellent wear and friction protection across a wide range of operating conditions and temperatures.

    Application. Red Line Synthetic 75W140 weight gear oil is recommended for use in 1979 to 2022 Mustangs, including LX, V6, GT, Bullitt, Mach 1, SVT Cobra, Boss and Shelby GT500 models. Check your Mustang's owner's manual for the correct weight for your application. Sold individually in one quart bottles.

    Application Note. Three (3) quarts of gear oil are required to fill a 7.5" or 8.8" Ford rear end.
