U.S. Fidelis sold me a car warranty and did not mention that I had to use AutoLife Xtend products in my oil, gas, and air conditioning in order for the warranty to be effective. When I got the products in the mail and saw the contract requirements, I looked at the products and they have no ingredients listed on the bottles. I called the manufacturing company for the product, ( The Choice Manufacturing Co. Inc.) and they refused to give out the ingredients. My mechanic will not put something in my car that he doesn't know what is in it, and I won't either!! Beware, that US Fidelis is not telling you the whole story when they sell this warranty! They have a hidden agenda! This is more about using an unknown product than getting a warranty! Don't do it!
