[QUOTE="ISFast, post: 328672, member: 1145"] Your talking about the acidic properties that both ethanol and methanol display. But that goes into other stuff like fuel having to mix with the oil and if there is water containment. Which we know both are hydrophilic. Also, if your not getting a complete burn from the fuel which most modern OEM stuff should be fine. Unless your Greg.... :jawdrop: I was referring to the fact you have to burn more fuel to get to the same place with the same driving conditions. Yes ethanol has a higher octane rating but the energy density of ethanol isn't there compared to 100% gasoline which equals more burnt fuel which should make the oil dirtier. e10 is about 3% difference and so on up to like e85 that is around 25% drop in efficiency. Just a quick search around on the interweb :Big Laugh: and sounds like its a lot of CYA incase the "optimal" ethanol isn't 100% spot on to specs. [/QUOTE]
