BOB, your test proves nothing and you know it. The only evidence I have seen on schaeffers two cycle oils are the pics you posted of the motorcycle engine. those pics where terrible. Lots of heavy carbon deposits on the piston. BTW I wonder why no one else uses PAOs in their two cycle oils? Deposits issues maybe.
I dis agree. It proves interesting imo. What I have found that has proved nothing is your opinions which is all I've ever seen. You talk about how you've used all these different brands, of course never schaeffers, so your opinions about schaeffers is non founded imo at this time.
I'm not saying you're right or wrong but I'll call it like I see it also. Lets also point out, that you were right, you couldn't tell nothing based on those pictures as the quality of those pics were extremely poor. There was no heavy carbon deposits on any part of that engine. The carbon that was on there was soft and would wipe off with my fingers. So, your thoughts based on some poor quality pics is understandable.
Most syn two cycle oils are ester based. I cant recall if I have ever seen a pao two stroke oil. Esters will take more heat,contribute to less friction, and decompose cleaner than a pao or mineral oil What evidence have you seen that the pao won't burn clean? You'd admitted you didn't even know there was such a thing as pao two stroke oil. Now you do. Next step, go through all the steps of trying and test it before qualifying your statements that it's not that good for what ever as you have in the past. I've done more research and have learned more on the issues between the ashless and low ash oils. As in all oils, you are only taking one SMALL part of the oil, and qualifying it as good or indifferent. If you follow the motor oils as you do here on two strokes, you'll know that an oil can really be a sleeper due to the different additives used by a blender. Question, How many two stroke oils have Molybdenum Trialkyldithiocarbamate let alone the Specific chemical identity withheld (trade secret) that they use? Have any idea how that might affect the oils performance compared to one that doesn't? No actual test for that. This is an unknown, just like in motor oils, same deal, you have other compounds/additives that come into play and only until you have used and analyzed can you truly compare how it is affecting the over all performance. I've got m/c shops using the 706, tim sells a pile of it for customers outdoor equipment, boaters using it. Just a pile of different things out there. Same as Amsoil and their ratios, seems they have a different reaction to the blend they have. Yep, I'd be slightly less likely to change the ratio but I really don't know what they are doing different that would allow for them to do this, so IMO, I wouldn't myself, but thats their product which they know as I know the schaeffers 706. I do know that the 706 has proved out for the corrosion protection as well as no exhaust port blockage from any carbon build up, boaters noticing increase hp/ no smoke and the list goes on. Highly recommend not making a total judgment on a specific brand of oil with just some basic details. As I've seen before, it can really come around and surprise you when you consider how the other part of the oil can affect what you know to be true in one not true in the other.
BTW, in those pics above, I suppose you can answer why the other two have carbon built up in the test tubes and schaeffers doesn't? gotta be a simple explaination since it means nothing more than someone running the oil in thier engine and pulling the heads to see how they look.
