Default Which Fuel

I know there’s been a lot of discussions on what type of fuel to use. I found this video that will explain everything for those that are not very technical and for those that are.

the thing i have to say in regards to this is quite simple.
whilst i agree with all the science.

if i am not mistaken the Jag is designed to run on 95 RON so therefore in the US you should use the premium.

In AUS we have regular is 91 RON, mid grade is 95 RON and premium is 98 RON.
where as in US it is 87 AKI (91ron), 89 AKI (92ron) 91 AKI (93ron) , 93 AKI (98ron) (however there seems to be some difference in anwsers of aki v ron, therefore it is only approximate)
i always run the 98 RON , not because of the extra octane it has over the 95 but because of the cleaning chemicals that manufacturers add.
so it helps keep the system clean. it is like running 95 and every so often tanks adding in a bottle of cleaner.
