Diesel vehicles

Gas engines can't process diesel fuel, so if you mistakenly put it in your gas-powered car, you'll want a tow to a service center to have it drained. Think of it like eating a toy car; your body is not going to be happy and you need to get it removed as soon as possible. To discourage this mistake, diesel nozzles are bigger than gasoline nozzles.

The three main diesel engines include Cummins sold by Ram, Duramax sold by GM (Chevrolet and GMC), and Power Stroke sold by Ford. Their differences, at least on a spec sheet, are slight. The Cummins is an inline-6, while the Duramax and Power Stroke are both V8s. Torque numbers between the three engines are within 200 lb-ft of each other, and often change year by year as manufacturers try to one-up each other on this important metric.

While diesel engines used to be more common in passenger cars, these days in the United States they’re mostly found in trucks, SUVs or cargo vans. Diesel engines are increasingly focused on commercial work and less popular than ever in consumer vehicles.

Sort of! All gas and diesel-powered vehicles will be phased out by 2030 because of legislation passed in the United States to combat climate change. Diesel vehicles are less popular than in years past thanks in part to fuel emission standards that have some manufacturers opting for greener alternatives.
