A friend gave me a litre of Milligan Bio Tech bio diesel solutions diesel fuel conditioner cause it's no good for warranty reasons.Says it improves lubricity,up to 10% increase fuel economy,reduced friction,up to 40% reduction in engine wear,cleans injectors,improves starting,reduces smoke and emissions.Says to mix 1000:1,and it is a canola based product.I never noticed mileage gains,smells just like bio diesel.It doesn't quiet down like 2 stroke,but how could it at 1000:1.It was free so I'm using it! Milligan Bio-Tech | Foam Lake | Saskatchewan | Canada | HOME is the website. I just looked at the HFFR chart and this stuff actually worsened lubricity. I guess I will just dump it all in and get rid of it,and buy some 2 stroke tmo!
