Winter blend gas and E/85

I thought I read of an alcohol sensing functionality....maybe I'm mistaken
There is a PID description in there for Torque but the SHO doesn't have the actual sensor so we are out of luck as far as I can tell.  I know I can't bring it up...
 
Several weeks ago I switched from Sunoco 93 to Gulf 93 and I saw my KR go from 4.5 to 2 and I was pleased. Then after several consistent tanks like throwing a switch my KR jumped back up to 4.5 on the Gulf. Thinking maybe it's the winter gas so not expecting any magic difference I tried a tank of Mobil 93. This is my best yet with so far a KR of 0.8. I also have found a source for E85 about 6 miles away. So I brought a 5 gallon can home with me for future blending experiments. Frankly with the readings I'm getting right now with Mobil 93, I'm not going to rush into blending. For the time being I'll sit tight and keep an eye on the Knock Retard.
 
I never checked the price on the Mobil but I imagine it's close to the Gulf as both of those stations are not price leaders. One of the better but not cheapest in my area was the Sunoco I used exclusively for years. The Sunoco is around $3.80 so I would guess the Mobil is still under $4.00. The E85 however was selling for $2.80. Such a bargain.....
 
Sounds like you ran into a bad supply of gas or something?

Good to hear you found some quality fuel and the elusive e/85.

Car seems to smile a bit when we pull up to the e/85 pump!

It's funny how the clerk was sort of rude when attempting to get my BP rewards card to work for the little $5 splash of e/85. Then respectfully had no problem when I returned to fill up shortly after.

Finally blended in enough E85 to hit about an E16 ratio and I am getting even better results. Still no knock and the throttle response at part throttle is noticeably improved. It just zips right along. I will continue to monitor it and see how she does...

Hey guys just some advice, to get a good estimate of how much gas you currently have in the tank divide your 'Miles to E' by your average miles per gallon. I used this to determine how many gallons of e85 I needed to hit e20 which is what I've been running 2 tanks so far with great results. The engine really sings and shifts are improved.
 
The big girl is just vicious with these 40 degree ambients....The throttle response is amazing, like my foot has a direct connection to the motor. Power? Hell yeah, 70 mph in the rain last night breaking tires loose.

As an added bonus, looking like I'm gonna wind up at 21 MPG this tank.

NICE!!!

The wife driving home last night was playing around and breaking em loose at 50 quite easily in the wetness.

How accurate is the fuel % equation in torque? Does it hit 0% when there are still 2 gallons left in the tank like the fuel gauge in the car does or is 0% out of fuel? If it works properly using it would be the best way to ensure proper blending otherwise it could result in improper blending.
 
Mine seems to be about a gallon off. If I use the gauge and an E85 calculator I have to lie about how much gas is in the tank.

So my resusts of 2 stroke oil are turning out to be awesome. I'll get some proof this weekend on a 400 mile trip.

I used to use that in my Silverado, worked like a champ....
