What grade/octane gas are you guys using and what kind of mileage are you getting with it? Had anyone tried low mid and high grade to see if there is a big difference in mileage? Thanks.
Here in montana it is harder to find ethanol that it is to not find it. The pumps that have the ethanol are mid grade but our low grade here is like 85 octane if i remember right and our mid grade is 88 octane and low grade is 85 on most pumps. Where i grew up in south dakota there where a lot of pumps with only ethonal but their octanes where 87 89 and 91-93 where they are much lower out here.Wow, another thread covering well beaten dead horse topics.. but ok...
As has been said a billion times...
use 87 UNLESS you can find ethanol free premium.
MPG is all the same between grades..
BUT, the ethanol kills MPG. Some areas (my state) can sell premium w/out ethanol. When I use ethanol free I get at least 3mpg better.
Hey, by the way.. What you say didn't sound right (I thought it was a nation wide thing) so looked it up..
Montana is among the states attempting to be a leader in the ethanol industry. Its E10 mandate was enacted in 2005.
Montana law also requires that all gas sold in the state includes 10-percent ethanol, with the exception of 91 octane, according to the All Business website.

Montana is also one of the first states to pass a law saying they can take the "contains ethanol" sticker OFF the pumps.. so they may not say they have it.. but they do.. and often up to 20% according to some websites I just read.
