Pro-long Super Lubricants

Prolong Super Lubricants, a brand of GoldenWest Lubricants, Inc., is the perfect example of an American success story. In the early 1990's, the founders started in the back of a small shop, packing the product themselves. Today, millions of bottles of Prolong products have been sold all over the world.

Prolong Products Have A  Lifetime Engine Warranty

 Prolong is the only engine treatment company to offer a Lifetime Limited Product Engine Warranty and also has the most generous eligibility requirements of any engine treatment warranty available. A vehicle less than 10 years old, with less than 100,000 miles on the odometer may be registered.Just purchase the 12-ounce size of Prolong Engine Treatment and add it to your vehicle's crankcase (the same opening where you pour in motor oil), complete the warranty registration form that comes inside the package and mail it to Prolong and you will receive a letter of thanks from Prolong, with a renewal form to use with your next application. Once registered, the warranty may be continued for as long as you own the vehicle, just by adding 8-ounce Engine Treatment Booster within every 6,000 miles or six months -- whichever comes first -- and mailing in the renewal form.
