...15% Cool Power...
Adam,
This more or less says it all...
OS in [link=http://www.osengines.com/faq/product-faq.html#q2]their US dealer's Q&A[/link] and Morgan Fuels, the manufacturer of CruelPower in their web site,
both tell you that for engines that have ABC/ABN/AAC piston+sleeve sets, all synthetic lube fuels are NOT recommended. Morgan recommends their own 'Omega' fuels for such engines.
Why can't people understand that!? What part of the clause 'not recommended' don't you understand?
In an effort to keep their planes just a bit less oily, people risk engine damage, inferior reliability, crashing, Etc..
