RON to Octane conversion?

here we sell 91 Octane (mid grade) and 93-94 Octane (premium)

is there a way to convert octane ratings to RON?

ooh, here we go.....

so our 12v calls for a minimum of.....
91 AKI (CLC)
or
95 RON (ROZ)

so going by this calculator it seems I need a MON number too to convert it all to a octane rating..

wow, confusing..<ul><li><a href="http://www.csgnetwork.com/octaneratecalc.html">http://www.csgnetwork.com/octaneratecalc.html</a></li></ul>

You need to also know MON

Then you can calculate the AKI (Anti Knock Index = "Octane" in US).

Also check <a href="http://en.wikipedia.org/wiki/Octane_rating">wiki</a><ul><li><a href="http://www.csgnetwork.com/octaneratecalc.html">Octane Calculator</a></li></ul>

What are you trying to do?

Look at the pump. Maybe it says what kind of formula is used to determine "Octane." According to wikipedia, Canada uses the US method.

RON is always about 4 to 5 points higher than the equivalent PON (Pump Octane number = AKI):

USA (AKI/PON) --- Europe (RON)

87 = 91
89 = 93
91 = 95
93 = 98

well....

all the pumps here have a rateing in "octane"

I am trying to convert the various "octane" numbers (eg 89, 91, 94 octane numbers on pumps) to the recomended min gas rateings for our 12V

eg..
91 AKI (CLC)
or
95 RON (ROZ)

trying to translate this AKI or RON number to a Octane number.

EDIT>> after reading your above post...

so AKI is the same as Octane?

Question re: Your '93 vs your '95....

...you've seen this probably (below)?

Do you run different gas in the two cars (two different C/R's & Min RON's)?<ul><li><a href="http://www.12v.org/engine/index.php?section=fe">Min. RON (fuel octane) AAH vs. AFC...</a></li></ul>
