Dear Sir: I bought a Toyota Tundra Pickup brand new off the dealer lot in 2001. I love my truck now as much as I did then. With one exception, it has never given me any trouble at all; which is saying a lot even though I take outstanding care of it. The one exception is the subject of this testimonial. I bought the truck new in June. In October, I started the truck on the first chilly morning of the year and it made the most gut-wrenching sound I have ever heard. I thought that I had let it run out of oil because it was grinding and knocking loud enough to wake the dead. This horrific sound was accompanied by heavy black smoke spewing from the tailpipe. There it was, my beautiful Sunfire Red Pearl Tundra running like a sick, old school bus. After a few seconds it stopped. I checked all of my fluids and they were on spot. I use only the best lubricants in my vehicles so I could not imagine what the problem was. Over the next few weeks it became a recurring problem. I knew that I could never convince the dealer that there was a problem because it did not do it every time the truck was started. I was starting to feel very let-down by the whole new car buying experience. Until a few weeks ago I thought that my truck was the only one in the world with this problem. It turns out that many others out there were suffering with the same issue (View similar testimonials at:http://www.tundrasolutions.com search forums for “grinding sound”) I found this information by chance but I’m glad that I did. When I realized that the problem was not going to go away just by doing more frequent oil changes with high quality (even synthetic) motor oils, I started looking for other options. I read some other testimonials about X-1R and decided that it couldn’t hurt, and it was worth a try before launching a battle with the Toyota Dealer. I can say now, after seeing that other customers had to have engine rebuilds for the same problem, that X-1R fixed my truck. It didn’t just help or reduce the symptoms; it eliminated them. After I dumped that first 8oz. bottle of X-1R into my engine, it never made any hint of noise or smoking when I started it up again. I just completed my 60,000-mile service yesterday (which included X-1R engine, transmission, and fuel system treatment along with the fluid changes) and the truck runs better than new. I can now leave it sitting for days in cold weather and start it in freezing conditions without even the slightest sound. It just roars to life. On behalf of myself and Toyota (who did not have to rebuild my engine) I would like to thank you for your quality product.
