Only 9ozs. of this quart were used and so almost 3/4 of the bottle remain (see photo). This Mopar lube costs almost $30 and up for a quart new! This weight is for front axles in late model 4X4 Jeeps, Dodge/Ram trucks. Possibly also correct for older vehicle rear axles, and of course anything that calls for 75W-85 gear oil.
