Re: Fuel Grade
When you fill up the tank, are you filling it 100% with the higher grade, or are you actually just mixing the higher grade with what's left?
If you are like most people, you are probably filling it with about a 75/25 mixture.
So saying the higher grade did/does nothing probably isn't very accurate.
And did you take into account that while you were experimenting with that mixture, the fact that the computer was "learning" to adjust to the higher octane?
I would think that before you make a blanket statement about the higher octane not making any difference, you ought to at least give it a fair trial period starting off at about the fourth full tankful of the higher grade.
By that time the mixture should be better than 95/5 % , and the engine computer should then be able to remap itself, to compensate for the increased timing afforded by the higher octane.
It's worth the thought.
