In other words, you're buying worse gas at a higher price compared to Shell V-Power.
If you require an octane rating higher than V power 91 and can use it up before it's best before date, Ultra 94 is the way to go. I was not implying that Shell is the best fuel to use but rather the fact that it is ethanol free. I made a point of not using any ethanol fuel in my twin big block marine engines for the reasons I noted as do many other boaters.
