To me co-products is the issue. It means that all the studies about cost, pollution, etc. are wrong.
However you may or may not be right I won’t question. What I know from very personal experience with ethanol additives in cars, trucks, small engines (2 and 4 cycle) tells me that it is nothing but crap when used as an additive. The less added the better if we have to have it. I’d hate to see what 15% or more is going to do now.
And just because a car manufacturer says “E85” doesn’t mean it is impervious. What it means is they’ve figured out what can make it past warranty and what won’t.
If you’ve ever had a car with malfunctioning TPMS sensors, you’d know that the TPMS sensors are government mandated and NOT covered under manufacturer’s warranty. On average is costs about $100 to replace a tire pressure sensor when the battery turns out to be a dud.
Your government at work “Here to help you.”
