Indeed most of the occurances were a few years back but it had been revised to include the below instance.

The FBO at PGD fueled a total of seven aircraft, which is the only day the FBO used the refueling vehicle with DEF-contaminated fuel. Of the seven aircraft, only three were fueled from the vehicle’s “front” meter, which is where the FSII injection line was located. To address the event, the FAA issued SAIB AIR-21-08, Engine Fuel and Control – Operation with Contaminated Jet Fuel, dated April 20, 2021
