Re: C12 vs pump gas
The readings from one gas station to the next will usually vary , and that's true across the nation . Certain Brand name stations will put only their own gasoline in the tanks , so they're more consistant . Others purchase which ever brand fuel is the least expensive on a given day .
And computerized , fuel injected engines can adjust themselves for changes in gas quality , up to a point . So very precise quality control isn't really needed .
If pump gas quality is a necessity , always go with a Top Tier gasoline . Shell belongs to that program , so does Chevron .
