My sister has an older Honda CR-V.
Honda specifically tells owners to NOT use more than 10% ethanol.
Here in Maine, some gas stations sell ethanol free gasoline......about $7.00 per gallon versus $4.90 - $4.95 for regular with ethanol.
Also, with the shortage of grain and corn for food and the high cost of animal feed, burning food is insane.
Correction.....my sister said that a gallon of ethanol free gasoline here in Maine is one dollar more per gallon than the regular brand of gasoline (which is 10% ethanol).
She always buys the regular gasoline, but will have to switch to ethanol free if the percentage of ethanol goes above ten per cent.
The regular gasoline with 10% ethanol is about $4.84 - $4.94 per gallon.
On March 31, 2020, the price of a regular gallon of gasoline here in Maine was $1.69 per gallon.
I wonder who was president back then? s/
