Significant Technical Input
Lightbulb Guess who's running 87 octane

That's right, me. We developed a variant of the ECUtune Stage One code to run 87 octane. It's purring nicely.

So I am guessing that you made the fuel maps even richer to do this? I am curious what the differences are.

PS - very exciting. 87 is finally just below $2 here. I would love to run that instead of paying $2.20 for 93.

Hey, you're lucky. In new Mexico it only goes up to 90 octane. I wish I COULD try 93.

Check this out. You may be able to boost up that octane to ~93 with no harm to the motor, unlike some additives.

Someone correct me if I'm wrong, but I'm thinking anything you do to enable an SVX to run 87 octane gasoline will worsen fuel economy to the point that you'll realize no savings over running premium.

Different methods are used to determine octane rating in Europe. 99-95 RON = 91-94 (RON+MON)/2.

RON = research octane rating
MON = Motor Octane rating

Europe uses RON and the US uses an average of the two to tell what kind of gas you are getting. I am trying to look for a reference to explain it in depth, but I can't find a good one right now.

Sooooo long story short, your 98 is approximately our 93.

From what I have just found, your "super" is our "regular 95" ...

-And here is another one that says:

... AKI 91 octane in the US is the equivalent of RON 95 octane in Europe ...
