Okay so on regular gas @ $2.40gal I was getting 20MPG

On E-85 @ $2.05gal I saw 18MPG

I have a 26 gallon tank, if that matters.

I just filled up my truck for only the second time.... it came full of gas when I got it and I am PRETTY SURE they put regular in it. Last fill up was E-85, as was today’s. I have just over 1100 miles total on it.

I’m trying to math the difference in cost versus MPG to see which is better cost-wise but my brain is still sick-fogged and I can make numbers appear with my calculator, but for the life of me I can’t understand them.

I really should have stayed home. Good thing work is slow AF.
