1991 Mercedes-Benz 300: petrol or diesel?

Petrol, diesel and hybrid versions go wrong in different ways, so each has its own figures from the MOTs these cars had during 2023–2025. Pick the one you’re looking at: the fuel is on the logbook and in the car’s MOT history.

Petrol 76% pass first time (all 1991 cars: 71%) Stands out: coil springs 2.1×, ball joint dust cover 2.1× 860 MOTsSee the petrol guide › Diesel 65% pass first time (all 1991 cars: 71%) Stands out: rigid brake pipes 2.5×, tread depth 2.3× 241 MOTsSee the diesel guide ›

Hybrid versions had too few MOTs for figures of their own, or weren’t sold.
