Years ago there was a real difference. Back in the day when every dealer had their own trucks. You could actually tell the difference when you used different kinds. Some brands cause spark knock, and some didn't. Remember Gulf NoNox?
ESSO now EXXON always gave my Fords the best MPG, However it was more expensive. I used it only on trips.
Now it all comes out of the same pipe.
