Do you really think there are many vehicles in Texas with block heaters?
For diesel engines its not always an option at the dealership. I bet a lot of new owners are unaware of a factory installed engine heater even exists on their trucks.
Plus almost all big rigs have engine heaters.
Nope. My car won’t start right now, and I’m sure many are in the same boat. My battery is fine, it’s just 8 degrees.
