The data indicates that the Jaguar X Type (2001-08) 5-door estate with a 3.0 V6 231 SE Auto predominantly features a 2.97-litre petrol engine, accounting for 100% of the sample. In terms of fuel types, the vast majority (98.5%) run on petrol, with a small minority (1.5%) utilizing gas bi-fuel systems. This suggests that the 3.0 V6 variant is almost exclusively petrol-driven, and the use of bi-fuel options is relatively uncommon for this model.
