RE: Car fuel for a boat?
I never said it can't be done, but to get 11% oil fuel to 18% would require 12+ ounces of oil and require two jugs to mix it all up. Not exactly ideal circumstances if you ask me. Not knocking it at all, just being realistic IMO.
Benol doesn't mix worth crap with some glow fuels, Byron's and Odonnells being two. SIG's castor is fine, and klotz techniplate is fine too.
I won't buy a used Sportster for the very reasons you stated. I just don't believe for one second that a fuel with any synthetic at all is going to run a sportster the way it should. Like many other engines, they were designed around castor oil in the fuel and not a synthetic. Look at be OS peeling liners... Most of the stories I've read, those users were using fuel with little or no castor. The guys that aren't afraid of castor don't get peeled liners as often. Granted, its probably coincidence.... OS is top quality and should be put on a pedestal. Okay maybe not a pedestal...
It is my opinion that special circumstance engines need a special diet. Bushed, lapped, and weird cylinder construction engines like the sportster should get a full castor diet, I prefer 25% oil for those engines.
This is all just my inflated humble opinion. I mean no offense, and I come from the "old school" belief that castor is king. To goo or not to goo is the question. I'll take the goo.
