In my experience Shell gasoline is good, better than BP or Speedway any day, but nothing exceptional. Their price premium isn't worth it to me. I get best mpg from Meijer fuel, and Conoco branded Flying J truck stops.
I just noticed a Pattern reading this...
BP and Shell advertise their Additive package. BP says it has "Invigorate" and Shell, well i dont need to say anything about Shell advertising its Nitrogen V-Power.
Perhaps, all these "Additives" take power away, and make the Mileage do DOWN in a Old engine, but help things in a Clean one, like those brand new cars they tear apart for their flyers for engines that had No Dirt in them at all so Shell can say it made them Clean?
Not a chemist, but i would think a Nitrogen molecule would take power away and/or mess things up in Gasoline. Shell seems to have messed with it enough that Nitrogen works for their Advertising and gets them certified, but i compare it to Too Much Ethanol in cars that dont like or arent used to Ethanol in Gas, that 10% figure...
Where i live, i put in just about any gas. I try to use BP but sometimes Shell is cheaper, sometimes not, sonetimes no-name is cheaper. Sometimes Marathon sells Premium for the same price as 89 and i use that. Sometimes i put in a full tank of 87. Trying to put some MMO in, need to get the RedLine, but in reality my gas Mix is just about anything.
I keep a log of the Gasoline i put in just so i can know what i added and when, and how much
I wonder if the lower stuff works Better at delivering Power.
I just checked a GasAmerica brochure too, it says their Gas (All of it) uses "Chevron/OGA Oronite" Cleaner, which "Exceeds Federal standards for Gasoline Detergency" so that should be some good gas too? Doesnt mean it is what Chevron puts in, but there is so much Conflicting information, particualtly when Ethanol is thrown into the mix some gas stations SAY they dont use it but i thought it was Federally Mandated...
... That any Gas without Sludge and Water, to which i add Marvel Mystery Oil in my tank, unless Name Brand is same price as No Name, in which case i get Name Brand, goes in....
