Lmao 231 for shipping of a 300 dollar item. No thanks
From what I have read, ethanol mixes are not linear. Most of your gains are around the e50 mixture and not with the e98 fuel. Mix it with some 87 octane and you will have much more fuel...
not true E98 is a higher octane and requires 15% more fuel than E85. Also, E98 is a more constant fuel. It a matter of whats available to you!
It is interesting to note that the blending response of RON and MON as a function of ethanol content is highly nonlinear. There is a substantial octane improvement between RG and E10, and between E10 and E50. However, between E50 and E85 there is very little difference in either RON or MON. It is well-established that properties of ethanolgasoline blends, such as Reid vapor pressure, do have nonlinear responses [4]. Surprisingly, the authors have been unable to find RON and MON measurements as a function of ethanol content that either support or refute these results.
