90-Day, Money-Back Guarantee
We are so sure you'll be happy with your purchase, we're backing it with a 90-Day, Money-Back Guarantee.
All we ask is that you try the product(s) for a full 60 days before deciding if you want a refund.
Why? It's simple, really. GO15™ is designed to slowly adapt to your specific engine. This means that it can take up to a few weeks before you experience the wonderful benefits it will provide.
Remember, your engine slowly began to wear over the months and years. Give GO15™ the time to slowly improve the efficiency and strength of your engine.
So, please allow GO15™ a full 60 days of use before deciding what you think of it. We think you will be very happy with the results. The best results have been an initial use of 1,000 miles, then a complete oil change with another bottle of GO15™ with the new oil and thereafter a new bottle of GO15™ with each oil change for maximum protection and performance!
We know you will love GO15™! If, after trying GO15™ for 60 days, you're not happily satisfied, send them back for a full refund (minus shipping).
