During the four-month transition window from September through December 2026, ADAC's approximately 22 million members can claim discounts at both Shell and Esso stations simultaneously. The switch results in a slightly smaller partner footprint, as Esso maintains around 1,100 locations across Germany compared to Shell's network of roughly 1,900 stations. Shell is concluding the collaboration to prioritize the expansion of its proprietary loyalty ecosystem, the Shell ClubSmart Program, while ADAC's existing fuel agreement with Agip/Eni remains active.
