I agree that with a frequently used vehicles and just like biodiesel used in cars designed for them, it’s not a problem. But, let the car sit, you have potential for long term affects from water separation and all it’s related running problems. Add fuel stabilizer for ethanol for gas left in your car for longer then a few unused months and it should be fine. Personally, I detest it’s use and feel all the unintended consequences just adds to the frustration of car ownership.
