The Center, which operates out of Minnesota State University, Mankato, just released a study that found an E20 blend "causes no significant change in performance of automotive fuel systems." This study, the fourth E20 project the Center has conducted, was all about the fuel pumps and sending units. Eight models of fuel pumps were run for 4,000 models on three different fuels (pure gasoline, E10 and E20). |
Another disingenuous report! Interesting how each of htese supporters do not look at the whole system but only cherry picked issues.
Note the highlighted text. Great, my fuel pump and level gauge will live! what about my loss in performance due to the lowered energy content of a gallon of fuel (i.e. worse gas mileage). The strain this fuel will put on my overburdened fuel mamangement system which will need to richen the mixture even more to operate at stiochiometric ratios. How will the resultant lean running impact my catalyst?
It is interesting to note what was omitted or overlooked in this research. They did not say E20 has no or postive impact to overall perfomance nor it's impact to anything OTHER than fuel pumps and level gauges. Why did they not factor in the loss in performace due to the changed A/F Ratio? How E20 afftect tailpipe emissions.
