Back in the highly fuel-economy-conscious late-1970s and early-1980s, with two OPEC embargoes all-too-fresh in the public’s mind, a large percentage of the car manufacturers doing business in the U.S. offered at least one diesel model. However, as fuel availability increased (along with a corresponding dip in gasoline prices) and emissions regulations were made tougher, diesel power for passenger cars and light-duty trucks fell out of favor in this country almost as quickly as it had fallen into it. The American motoring public had, alas, moved on.
However, the pendulum is starting to swing back the other way. Today there are diesel cars available not just from the “usual suspects” (i.e. Audi, Volkswagen and Mercedes-Benz), but also some you might not expect like Chevrolet and, pretty soon, Mazda. Inevitably, there will be people who aren’t used to seeing other people filling their sedans from the green-handled nozzles, and will (erroneously) try to warn their fellow motorists. Will the warnings be as dramatic (or plentiful) as the ones given by the folks in this cheeky new Audi commercial? Probably not. But rest assured, you will get warned.
