In fact that's not quite the case. The government website only refers to European models. Hence........
E10 petrol is cleared for use in all Toyota European petrol models made from January 1998, excluding:
Avensis 2.0 litre with engine 1AZ-FSE made between July 2000 and October 2008.
Avensis 2.4 litre with engine 2AZ-FSE made between June 2003 and October 2008.
These models, and those produced before 1998 should continue to use E5
The Alphard is an import.
But I hope you're right about the same engine being used across other, European, Toyota cars. Thanks.
