Widely varying quality of the product is part of it.
Isn't there a standard to which this type of product is produced?
Think about it. If the attributes mentioned above were factually true, E85 would solve a lot of problems many of us have experienced...
Don't worry about installing a 4 row Aluminum radiator, or checking the clearance on the divider plates in your water pump. E85 will drop your running temp by 20 degrees! Hell, add water wetter and you won't be able to get up to your thermostat's temperature rating!
No worries about static or dynamic compression ratio. The 105 octane of the E85 will resolve that. Run those old heads without worry!
C'mon guys! You know better.
I'm a hobbyist. Not a professional. Don't be hatin'!
