We did have a diesel boom in the 1980s, but it was pretty brief. The F150, Ranger, Chev/GMC 1500s, Mazda, Toyota, Isuzu all had diesels. A bunch of other GMs (Oldsmobile of course) and Ford (Escort, Tempo, Lincoln Continental and Mark VII) as well as all the Germans had them. When fuel prices dipped, they became a tough sell, and except for VW and Mercedes within a few years they were all gone.
Diesel supply is pretty static. If demand really bumps up, expect to see price at the pumps to ramp up too.
