A. Yes. Properly formulated synthetic drive line lubricants can offer extended lubricant service and component life compared to mineral oil or conventional type gear oils.However, there are different designs and compositions of synthetic oils and just because an oil is listed as synthetic, it may not automatically provide optimum performance for either lubricant service or component life. Ask the supplier what type of synthetic base is used to produce the synthetic drive line oil.
Consult with your drive line manufacturer to find out what the lubricant and service recommendations are for your vehicles.
