Honda signed deal with Castrol to supply Edge - H specifically for Honda engines.
Somehow they forgot to make one that fits the SAE/ACEA classifications called for in the owners manual - should be ACEA A1/B1,A3/B3 or A5/B5.
The label from the Castrol Edge H oil looks like this - as supplied from a Honda dealer - please see attachment.
Stick to a good supplier, and for the UK something that any of the above classifications and grades 0W-20, 0W-30, 5W-30. The lower he number the less viscous and therefore gives slightly better mpg.
