Those of you with the SVR what fuel do you use, normal 95RON or the high octane 98RON.
What does LR recommend?
Thanks. SVR 2018 in Santorini Black.

95 is fine for a LR, you won’t notice the difference between the two and fuel in this part of the world is good quality and consistent, so save your money

As an ex engine development man before I moved to SVO, technically the engines are more than happy running 95RON, but there's definitely a happier engine when filled with 98, especially when driving "enthusiastically" with a lot of boost.

Thanks for the replies guys, and its really good to have Dave,s expertise on here helping us out. SVR 2018 in Santorini Black.

Ooooh, tin hat on. incoming! I bet this'll shortly be the longest thread here.

IMHO the premium fuels do make a difference. Perhaps not the performance boost you're expecting to feel, but certainly in the fuel efficiency.

I routinely find that with premium petrol and diesel, Shell in particular, give me many more miles per tank. Then at the other end of the scale, cheapo super market fuel is far worse.

I use any brand apart from supermarket etc. Mainly shell, wouldnt use anything out of a supermarket as it is trash Current

All fuels in the UK are produced to British Standards whether from a supermarket or a brand like shell. The supermarkets buy their fuel from the brands refineries they don’t refine themselves.
The premium fuels might give higher mpg but at what cost per mile ? And is very hard to prove either way.
If your going to track your SVR then when you get to the track buy some 103 race fuel then drive the wheels off it and if you are as skilful behind the wheel like Chris Goodwin you will benefit from the higher octane, if your driving on our roads stick to 95 it’s more than adequate and what these engines were designed to run on

200k miles in JLR V6 diesels in 3 different vehicles - all almost exclusively on supermarket fuel - never a problem.

I spreadsheet every fill, always have, and tried the "super" fuels from each supplier - 3 tankfulls in a row to give them a fair test - they made NO difference whatsoever to economy, nor performance. Excel doesn't lie.

To state that "supermarket fuel is trash" is, to my mind, plain wrong. If you are happy to pay more for the same thing, carry on. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

Long ago, when life and cars were much simpler.............there was definitely a notable difference between 2 star and 4 star petrol (and I am sure I remember some 4 star pumps serving up 105 octane).

But back to this century - in 2003, I took delivery of an E46 M3 and did experiment with running regular unleaded and better quality unleaded - both Shell. There was a notable difference and I tried my experiment during the winter and summer and in particular during the summer, my M3 ran much better.

I can't comment if today's engines perform and are just as efficient on regular / higher octane fuel. Since my M3 experiment, I have just stuck to buying the highest rated octane I can find.

The fuel sold on the supermarket forecourt is exactly the same as that sold by your mainstream brands. It comes from the same refineries, is transported along the same pipelines and is stored in the same tanks at the distribution depots.
The only difference is the additive blends that are mixed with the fuels at the point the tankers are filled before distribution. These are different and are developed by the respective companies but ALL have to legally comply with the relevant minimum standard of quality. Supermarkets buy their additives from the same product developers that supply Esso, Mobil, BP etc. There are no chemical experts within Asda, Tesco and Sainsbury’s. On occasion, when a new additive has been developed, it is initially distributed with sole rights by that company but does eventually go on open sale as new additives come to market.
There is negligible difference between standard 95 RON purchased at your local Shell and that bought from Morrisons. The same goes for diesel. If you’re willing to pay more for the mainstream brand, it’s for no other reason than you have been drawn in my the marketeers.

The difference between 95 and 98 RON petrol is obvious and some engines are specifically designed to work with the higher octane rating. If an engine has been designed to run on 95 RON, there is no reason to use the higher octane product. There is little to be gained.

I had a visit to BP Grangemouth refinery in 1997 which supplies all of Scotland and the very North of Englands fuels (or did back then), no matter what fancy badge the fourcourt had it still all was refined at Grangemouth - it was the same BP fuel. Although I had heard all Scotlands fuels came from there, it still tickled me when I saw the tanker fillup area with queues of different brand tankers waiting.

I now fillup wherever and whenever I need fuel - it's the same base product. 13MY Range Rover Sport Autobiography SDV6 - mine

My preference is always 98 over 95 and ideally from Shell  SVR with a few bits from Urban and Glohh
