There is absolutely no proof that brand X gives better MPG than brand Y and the oil companies are very careful not to claim so – lest they contravene advertising regulations. If anybody could prove me wrong, I'm happy to be preached to!![]()
I dont buy into any of it, ive never ever seen any difference in performance between any standard grade EN228 unleaded. You are probably aware of what my father is/does so the topic of dinner conversation at parents dinner parties have always been petroleum products and associated distribution systems since i was very young. Go and visit your local terminal, you will see many tenkers with different brands filling from the same storage tanks. The only difference are additives, which i think most people would agree are marketting blub.
