Using fuel additives like Fuel Factor X Advanced Fuel Treatment from My Daily Choice should not void the warranty of your car. However, you should always check your vehicle owner's manual to see if it mentions any restrictions on the use of fuel additives or similar products.
Manufacturers sometimes caution against using certain types of additives, so it is important to check before using any product in your vehicle. If you are unsure about whether a particular product is safe to use with your car, it is always best to consult with a qualified mechanic or contact the manufacturer directly for clarification.
