E20 Petrol | Phase Separation, Ethanol %, Monsoon and RUSTED TANKS

Ethanol in petrol will kill your new car, E20 petrol attracts ants, E20 petrol is destroying fuel pumps - these claims are viral on social media. In this part we discuss how phase separation happens, how much time does ethanol blended petrol take to separate into water and petrol. We also see what chemical reactions happen inside the combustion chamber of your car. How much truth there is to tanks rusting claims. Brazil has 40 years of experience with ethanol blended fuels.

No chemical reaction; ethanol is a cosolvent; blends hold small water in solution and burn it harmlessly; pure petrol lets water pool. Bell Performance; CropWatch UNL Water tolerance RISES with ethanol % E10 separates easiest; higher blends resist. E10 ~0.5% water (~3.8 tsp/gal) at 60F, less when colder. NREL 2016 humid-env study (ethanolrfa.org/file/1793); USPTO 8439984/8911517; PetroClear ~7000 ppm at 70F Timing: constant heat+humidity, E10 took 3+ months to phase separate; petrol became unfit ~1 month BEFORE separation. NREL via Agri-Pulse; agri-pulse.com/articles/7540 Brazil: ethanol fuel since 1979; gasohol E18-27.5% (now E27) + E100 hydrous; flex-fuel since 2003 (~94% new cars); anhydrous blended at TERMINAL (not pipelines) + quality monitoring to prevent separation. SciELO "Brazilian experience with ethanol fuel"; HFW; Wikipedia Monsoon real risk = water ingress into station underground tank; any fuel then contaminated; station housekeeping. India: BPCL Ratlam CM-convoy stall (heavy rain water in tank); Gujarat/TN/Kerala dealers seeking ethanol-free fuel in monsoon. Deccan Herald (Ratlam) Storage: E20 uses existing USTs (must stay dry); E100/high blends need dedicated tanks/pumps/seals (Gadkari E100 framework). Autopunditz; Minnesota Commerce; PetroClear Tanks: 75% of car fuel tanks are multi-layer HDPE plastic; steel only in older/commercial/bikes. Corrosion needs phase separation to put water on metal; alcohol also loosens existing rust in old steel systems (solvent). Compliant cars use fluorinated (FKM) seals; old nitrile seals swell.
