Put gasoline in my freightliner

Its probably fine. There was probably enough diesel in the tank to dillute it.

 

30 gallons wont hurt it

 

In a pinch you can use gasoline as anti-gel,but 30gal is a little much.

 

A bit of premature wear on the injectors from the reduced lubricity, how much depends on how long it ran. But nothing to tear into now.

 

We all make mistakes , best of luck.

 

Saw that. I should have been clearer, it sounds like you caught it soon enough that the only issue is you might have reduced the life of your injectors by a small amount. The gas dramatically reduces the fuel's lubrication abilities. But unless there's issues after you restart it, it's not worth opening it up to have a look see.

 

Yep. Drain the tanks, blow out the lines, refill with diesel, prime it and get back trucking.

 

Just curious, what kind of trailer are you pulling?
