I unknowingly put a half a tank of gasoline in my 2020 eco diesel. Half diesel half gas. Took it to the dealer and explained that I thought that I bought bad gas. The truck ran fine. It was just hard to start. They said to just drive out the bad gas. After about 150 miles of driving and the starting problems getting worse. I left it at the dealer for diagnosis. They informed me that it was filled with gasoline instead of diesel. They Wanted to replace everything for about $5000.00 dollars. I told them to drain the gas and refill with proper fuel. They did, and it has ran fine since. Does anyone know if I could have actually caused major damage?
