Well, since Wikipedia is not reliable ...
I searched on google scholar and found dozens of pages just the same opinion: the RAF used 100 octane at the beginning of the Battle of Britain.
Scientific knowledge is built upon scientific consensus.
Please, someone show me a literature review that contradicts the dogma of the 100 octane in the RAF ...
Here are some of the references that I gathered in google academic (only those with full text or intelligible):

This issue impacts the credibility of CLOD as a simulator and should be treated based on more extensive research.
