Want to share with my impressions. This Saturday I could not resist and tried a new fuel called "BIO 100". This is our Ukrainian version of an alternate fuel. No idea why manufacturer calls it "BIO 100" if it has RON 106 and MON 91. The fuel is made of 60 % of absolute (anhydrous) etanol (bio), 30 % of gasoline (stable, made of natural gas, light fractions) and 10 % of MTBE (or ETBE).
Though I put only 10 liters of BIO 100 into the tank with 30-35 liters of RON 95, if I can call it "for safety reason", my first impressions are very positive these 3 days: engine is running more smoothly (less noise), accelarates slightly faster and seems became more tolerant to a choice of gear. However, I still have some worry about a stability of a new composition (I mean BIO 100 + RON 95) and certain aggresivity of etanol on fuel system. According to the manufacturer they found that only at above 50 % of etanol the composition remains stable for a long time and does not becomes differenciated. The manufacturer also claims that tests showed no car modifications are required for BIO 100. But I think this claim is quite doubtful.
No clue whether or not it will have an impact on Mazda6, but I shall consider this experience as very useful. At least I know that nothing will happen at once.
Anybody knows at which concentration etanol would be tolerated by rubber/plastic materials and how to offset a corrosive effect on metal parts ? Thank you in advance.
