<p>I did not mean to imply that a single fuel must be used. But I don't really note exact spec they are working toward. I guess ideally there would be as many grades as there once was, as engines were designed and manufactured for a specific octane and lead contend. The 100LL was a compromise. Both octane and lead content above the old 80 grade and much less than the 145 grade.</p>

<p>I read from the Swift information page, but I didn't quite understand all of it. Like you, I would think a 100 LL replacement would cover all engines now using it, but then why have two different grades to replace 100 octane LL? I will call Swift and ask.</p>

<p>Gil, It is my understanding that by definition, the approved replacement for 100LL will be acceptable for any engine that currently runs 100LL. Otherwise it would not be a true replacement. 100LL itself was a compromise as it replaced three grades I know of and there may have been more. Seems I remember 80, 100, 145 but I don't rely a whole lot on my memory. :-)</p>

<p>Swift has been testing UL 94; don't know if that will meet your needs. Shell is also testing, but I'm unsure what octane rating they claim.</p>

<p>Not sure if this fuel will fit the bill, but they had a display at the Light Sport Expo this week. They are up and running and trying to expand their distribution.</p>
