Most Spaceships are fitted with an environmentally friendly (Euro 3) 2.4-litre engine. Most Spaceships have this petrol engine.
The exception is the Cosmo VW Campervan, which comes with a diesel engine, so it must be fuelled up with DIESEL!
On each campervan's specification page you will find the fuel consumption of each campervan category. Fuel consumption is an estimate and will vary based on how you drive, the terrain you are driving, the average speed on the open road and urban usage.
