I always go for Shell V Power in my Morgan
The reason being, a good friend of mine is an architect that specialises in Petrol forecourts and he told me a few years ago that Shell were the only company at the time to replace all their filling station tanks to be absolutely moisture free to eliminate any water that can get into the fuel when being stored
This coupled with the additional lubricants means it’s the choice for me
The only issue is it can be on some forecourts be stupidly expensive so I make sure I know a few Shell garages on my regular runs where it’s at a sensible price
Any extra performance is a side issue and I probably wouldn’t notice it much the way I drive anyway
It’s only about protecting my engine with the hope it will help extend its life
