e10 is regular gas that 99 % stations sell, e15 is 15% ethanol and 85% gasoline, or 5% more ethanol. NO auto maker requires e15. But the EPA is madating more ethanol be mixed into our gas. Cars made before 2002 cannot use e15. No small engine such as lawnmowers, chainsaws and leaf blowers should use e15. Check in with Michigan discussion site for more info.
