This is a new one to me!
Could i ask firstly, why did people think they would "explode"?
and why would a JDM be more likely to have had better fuel in both countries?
Literally 100000, s of imports of all sorts in this country without issue, jap fuel is 100ron so just run in on optimax or equivalent, which most owners uk or jdm do anyway.
Exactly so here and in Japan no 95ron would have been used but the UK cars I bet 95ron would be used most often.
