Generally
1 quarter = 0.946 liters of high-quality rear axle oil. This oil is suitable for all Cadillac rear axles, even those with multi-disc brakes. You don't need to check what kind of rear axle you have, this oil is the right one and we also think it is the best. Sometimes we have Quaker State and sometimes we have Gulf in stock and they are exactly as good and replace each other.
