Average On-Highway Diesel Price/Gallon...

My tractors are diesel, but I don't use enough fuel in them matter that much.

But yes, this is a large part of the reason for the hyperinflation. And much of the blame is on Biden.
I own two diesel trucks and two diesel tractors. I use off road in the tractors but highway grade in the trucks. The diesels get about 70% better mileage than the gasoline trucks per horsepower/torque. I am about to make a 650 mile round trip hauling this week and it will cost me way more than last year. Inflation is rampant everywhere. Yes it hits me directly in the wallet.
