My fuel pump and injectors failed while I was driving, stranding my truck in the middle of traffic right where a city street was changing to a country road. The GMC dealership falsely claimed that this was caused by using unapproved fuel. The fuel I used was b20 biodiesel, with 80% renewable diesel, which meets diesel specifications and is a legal road fuel in California. They also claimed that a cascade of other problems were all caused by my fuel and refused to apply my warranty.
