⚠️ Mercedes-Benz overview
Mercedes-Benz sells luxury sedans, SUVs, vans, and EQ electric vehicles in the United States. Gasoline-in-diesel on legacy BlueTEC and Sprinter fleets remains a high-severity exposure. EQ models have no fuel tank. Use XENTRY/Star TekInfo for all tank access.

Fuel system notes
- US passenger diesel largely wound down after 2018—still verify fuel door on every repair.
- Sprinter and Metris commercial users face fleet misfuel at truck stops.
- DEF is separate from diesel fuel on BlueTEC and Sprinter—never mix.
