Oldsmobile Cutlass Supreme Diesel
In the late ‘70s, American manufacturers were all about fuel efficiency and downsizing. The era of big cruisers and powerful gasoline engines of the ‘60s was gone. Everybody was trying to find a way to introduce new, innovative technologies. Oldsmobile was on the forefront of this new trend with the introduction of the diesel engine in passenger cars.
In those days, American buyers were unaware they could use diesel fuel for their cars. European customers already had a couple of diesel cars on the market, but for the U.S., this was new. Oldsmobile introduced the 4.3-liter V8 diesel engine as an option for the Cutlass line. But soon this model was a subject to an enormous amount of recalls and engine swaps.
Simply, the 4.3-liter had the tendency to explode and shatter during normal driving. Even though the passengers weren’t hurt, the car was unusable and only good for scrap. Oldsmobile later introduced the 5.7-liter diesel that was somewhat better and more durable. But the 4.3-liter is the worst diesel engine in history.
