New to playing around with E85 and wanted to make sure the method I'm using is accurate. I'm using the 100ml tube where you add say 25ml of water then add the mixture in to fill it up to 100ml, shake and watch the separation line and then do basic math. I filled up a 30 gallon barrel with E85 since the nearest station is 30 minutes away. After measuring the contents of the barrel I'm coming up with E89.3 which makes me happy if it's accurate as I was afraid I might have gotten E75 or something low for the winter. The tank I already had in the car I had already adjusted to where my logs were clean but couldn't get a hose down far enough into the tank to siphon off so I had to add 6 gallons of fresh gas to get it high enough to siphon some off to test. I had a 1/4 tank and running through the testing showed by new tank was only at E12 and trying to do backward guess work I came in that I had previously only had maybe an E25 mixture in the tank.
So my questions would basically be is this method really accurate and if so does it really only take E25 this time of year (texas in the 70's) to make the E30 Cobb mapp happy?
Any easier way to pull fuel samples other than a cheap siphon pump as it seems tricky to get that hose down in there where it actually gets anything.
