Favorite Petrol Fuel?

[BevC]

My previous 163 didn’t get on with Esso diesel, so I only tried it once. I believe they have recently reformulated and I had a low fuel warning in my new 180 diesel and bought some on the way home. The next tank I put in Shell V Power, so was able to compare. To my amazement not only did my 180 prefer the Esso (much smoother, quieter and slightly better performance), but I am also getting better mpg. The best thing of all is that the Esso is cheaper than the basic Shell. Happy days.

I put half a tank of 99 in at the w/e to do some kind of 'objective-ish' test against the standard 95. I agree with Phil the engine did seem more eager, I didn't do a mpg test this time as I've done it before and I did get a few extra mpg with 'Super'. But I was impressed with the 99. I wonder whether 99 has more of an effect with the V6 engine? Maybe.

I'm wondering what JLR is trying to tell me with their recommendation:

On the 3.0 they're calling it "premium unleaded fuel with minimum 95 ROZ" and on the 2.0 they're calling it "super with minimum 95 ROZ".
So what makes a standard 95 fuel a "premium 95 fuel"?

In some markets the premium fuel is 95, and in a few markets it is 95+, Some countries i've been to (on a motorcycle) have 91/92 Octane, this causes horrendous 'pinking', (pre ignition in the cylinders, that can cause serious damage), so need to beware of that. All JLR is saying is 'A minimum of 95).

I use supermarket fuel all the time, and maybe every 5th or 6th tank being premium grade. And if i travel 'abroad', on departure and arrival home to UK i always give it the best i can get to help clean out any low grade stuff.
