Most people have heard of synthetic oil for your engine, but did you know that you can get synthetic oil for your transmission, and rear axle? The guys at Royal Purple http://www.royalpurple.com/ have a full line of lubricants for your car. The main advantage of using synthetics in all your moving parts, is the reduced friction. You can free up horsepower and save money with increased gas mileage. I changed all the fluids in my Dodge Stealth and noticed an instant improvement, plus I knew my car was being protected from friction with the best lubricants available.
