My car is an import and got it today. Importer says to use 95. Is there a way to check what fuel is recommended 91 or 95 ?

 

Most Mazda Jap imports need 95, compared to their NZ new equivalent. I had this with my Atenza. Is there a sticker on the inside of the fuel flap?

 

There is nothing but Ive read about it the and it states that the skyactive engines needs 95 which i have

 

When in doubt use the highest octane available that is recommended in the owners manual if,
1. You have over 100k miles
2. You have verified that you have no excessive carbon build up in the intake manifold, intake valves or combustion chambers.
