There are two separate issues here.
One is to do with the “engine cleaning” additives that top notch fuels provide. Shell is a specialist hydrocarbon fuel producer, whereas Tesco sell baked beans. I suspect there’s a reason why Momentum is cheaper than V Power, and it’s not to do with volume of sales. Ok, Tesco could sell fuel as a loss leader, but I trust Shell more that Tesco when buying petrol (but I still get my beans from Tesco).
The second point is octane rating. If they are the same (99) then there shouldn’t be any difference in performance. Whether or not some of the other super fuels (e.g. Esso or BP) which are 97 octane perform noticeably worse, personally I can’t say that I’ve noticed any difference. In theory the anti-knock systems in the car should prevent potential damage caused by lower octane fuels (<98) but will ultimately cause a reduction in power.
