Thank you Jim
Here, Down Under, our Octane ratings are described a little differently.
We have, 91, 95 & 98.
We are told, and know, that 91 Octane is satisfactory in the KL Cherokee, however I choose to put 95 Octane in my ride. Yes 95 Octane costs 5-8 cents more a litre than 91 but...... (there are many reasons why, and there have been many debates on this subject..).
So I won't buy the highest Octane fuel for my KL, but I won't buy the lowest Octane either.
Thanks again Jim
for showing us the results of your fuel economy test
