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 in.
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.
Welcome to the growing family of smart Prolong users who benefit by treating their engine with Prolong at least twice a year and have the confidence the Prolong Lifetime Warranty provides: The Ultimate In Protection & Performance®
See below to read the actual warranty. Click here for Prolong’s Frequently Asked Questions about the warranty.
This Limited Product Warranty is issued by GoldenWest Lubricants, Inc. (“GoldenWest”) to the original Consumer (“Consumer” or “You”) who purchases and properly installs, or has properly installed, Prolong Engine Treatment and who otherwise satisfies the terms and conditions of this Warranty. The term “Warranty” refers to this Prolong Engine Treatment Limited Product Warranty. The term “Product” refers to Prolong Engine Treatment and, for purposes of Warranty renewal (renewal terms and conditions may be found on the reverse side), to (“Vehicle”), as identified by the Vehicle Identification Number (“VIN”) on the Warranty Registration Card, for the specified duration of Consumer’s ownership or lease period of the Vehicle.
Yes, the Lifetime Limited Product Engine Treatment Warranty may be extended on an eligible vehicle for as long as you own it… the lifetime of your car! All you have to do is use Prolong Engine Treatment every 6 months or 6,000 miles and send in the renewal information to the GoldenWest Warranty Administrator, 1937 Mount Vernon Avenue, Pomona, CA 91768-3312.
Under the law, a limited product warranty only covers or applies to what a product does or effects, so the Prolong Lifetime Engine Treatment Warranty covers all lubricated parts of a vehicle’–s engine, provided the required oil level and service are maintained and Prolong Engine Treatment is properly installed. Specifically:
Prolong offers the most generous engine treatment warranty available, allowing coverage for vehicles with up to 100,000 miles! Most of the vehicles on the road will qualify, and remember, a high-mileage vehicle that doesn’t qualify for the free warranty certainly still benefits from the use of Prolong Engine Treatment and Fuel System Treatment!
Unfortunately, warranty coverage is limited to residents within the United States at this time. Fortunately, where ever, whenever and whatever you drive can benefit from the protective properties of Prolong Engine Treatment in the crankcase.
An odometer reading of less than 100,000 miles is required to enroll your vehicle for the Lifetime Limited Product Warranty. Once registered, you may continue warranty coverage for as long as you own the car, by applying Prolong Engine Treatment Booster every 6 months or 6,000 miles, whichever occurs first. Even though a vehicle with more that 100,000 is not eligible for initial warranty registration, it will certainly benefit from the application of Prolong Engine Treatment to protect against friction and reduce operating temperatures.
Within several weeks of your mailing in your application, you will receive an appreciation letter from Prolong confirming your warranty registration that includes a renewal form for your future use. If the vehicle does not qualify (mileage too high, etc.) or if omitted information is still needed, you will receive a letter of explanation from the GoldenWest Warranty Administrator.
Providing your vehicle still has less than 100,000 miles on the odometer, you can re-register your vehicle again, just like you originally did. Purchase and install the 12oz. Prolong Engine Treatment, then complete and mail in the registration form. There is a short waiting period after the initial registration before the Warranty takes effect. This waiting period is waived for Warranty renewal.
You can enroll as many vehicles as you want. Each vehicle is separately registered, providing it meets the eligibility criteria. Each vehicle must be initially treated with 12 oz. Prolong Engine Treatment. Application of Prolong Engine Treatment Booster every 6 months or 6,000 miles and a renewal form are required to continue Warranty coverage.
No. The Warranty is only valid for the consumer and vehicle originally listed on the Warranty registration card. Providing the sold or transferred vehicle is still eligible, i.e. less than 10 years old, and less than 100,000 miles, the new owner can register for a new Warranty when he or she adds Prolong Engine Treatment.
Purchase and install Prolong Engine Treatment Booster within 6 months or 6,000 miles of the first application. Use the renewal form sent to you from Prolong by mail after initial registration and each subsequent renewal. Mail to GoldenWest Warranty Administrator, 1937 Mount Vernon Avenue, Pomona, CA 91768-3312.
The Prolong formula treats the metal of your engine, using the motor oil as a conduit. In order to maintain the maximum level of protection first achieved when you install Prolong Engine Treatment, the product needs to be re-applied after an oil change. A certain amount of the product remains on the engine metal, so the full 12 ounces is not required for replenishment. The 8-ounce Booster size of the product is sufficient and more economical. However, if you wish to again apply a full 12 ounce treatment, it is perfectly fine to do so. It is not detrimental to the engine, just less economical.
Certainly. Many professional service facilities offer Prolong Engine Treatment as an option for your oil change package. You may want to keep that in mind when choosing a place to take your vehicle for maintenance. Facilities offering Prolong Engine Treatment also have the warranty documents to provide to their customers who have our product installed. Be sure to get the form, complete it and mail it in.
You may also purchase the product at your favorite retailer for automotive supplies, then take it with you to the service facility and have it installed. If you do this, you will complete your registration form with the date and odometer reading at the time of the service, just as though you were putting it in yourself.
Return to the facility within 6 months or 6,000 miles and ask that Prolong Engine Treatment Booster be installed with your oil change. Complete the renewal form sent to you from Prolong and mail it in to: GoldenWest Warranty Administrator, 1937 Mount Vernon Avenue, Pomona, CA 91768-3312.
Many top-quality dealerships are installing Prolong Engine Treatment in their new and pre-owned vehicles, recognizing the credibility and added value presented to interested buyers. These dealerships will either present the warranty to the buyer at the time of purchase, or will place it in the vehicle glove compartment.
The warranty document has specific, step-by-step information for the claim process. Prolong Super Lubricants has appointed a very experienced claims administrator to review and insure claim requests are processed in a timely manner. The number provided in the warranty is strictly for reporting a potential claim and receiving a case number and instructions.
