The oil manufacturers have had a technical method for recommending ratios but it has never been disclosed. So I studied about 2 stroke engine oils and I came up with a technical method depending on the oil viscosity and flash point temperature, and also depending on the engine and type riding done. I think my method pretty much parallels the oil manufacturers. If you want to read up on this topic please go to my site at www.dragonfly75.com/moto/oil.html
Interesting. People in my area who ride a lot of low speed single track trails tend to like oils with slightly lower flash points so that the oil will burn more completely and not leave a mess on the muffler. I like Motorex Crosspower. Too bad that wasn't mentioned in your findings.
That's a good tip. I couldn't find full data on the Motorex oils and so I didn't include them. I need to ask the company for them.
