My wife's 2014 Chrysler T&C does with the 3.6L Pentastar engine. It doesn't get nearly the mileage on E85 so we stick with E15 around town and E10 on road trips.

Just my $0.02
Have you done a MPG= calculation? E85 getting worse but costing you less? E85 might be the best investment for Highway miles? Thanks for sharing.

I have run a few trials and they have been unsuccessful. I use the Fuelly App to track fill ups and MPG's. In my area E85 is usually about $0.10 cheaper than E15 and roughly $0.50 cheaper than E10. So from a cost perspective if we assume E10 is the base line E15 is the best bang for my buck.

High level summary for in town daily driving, not a scientific experiment by any means but several tanks of each to compare
E10 = $3.499 and ~18MPG
E15 = $3.099 and ~17MPG so compared to E10 it's a savings of 11% and mileage degradation of 6%, therefore +5%
E85 = $2.999 and ~16MPG so compared to E15 it's a savings of 3% and mileage degradation of 6%, therefore -3%


Sorry this is how my engineering brain works.

That is excellent data & we are on the same brain wave. I'm also a fellow Fuelly App user on every fuel up w/my F350. Great App! Even use Gasbuddy card too. If you want to save even more than Gasbuddy grab the "Open Roads" Diesel card. It can only be used at select truck stop diesel lanes but has a huge savings for diesel. They were going to do a Gasoline card but they've canned it for the time being.

I honestly didn't know too much about the Ethanol MPG except that everyone has usually claimed they get less mileage on higher E amounts. Which sounds like your situation is no different & according to your own math it appears there is a sweet spot depending on the current prices. Unless you want to save the world on E85 there is a cost savings by running E15 vs E85. I was just thinking that buying E85 on a long highway trip might net you the best dollar & save the world if you get at least got 17+. (y) Thanks for sharing!

This is completely different topic but you have a Chrystler & I love the old Popular Science or Popular Mechanics magazines. I stumbled across one from around 1986 about 10+ years ago & there it was advertising the New Yorker's revolutionary Electronic Transmission. We can have a good laugh about it now but it's always neat to see what they were showing in the old days. I'm 38 just for reference so 1986 is still old to me even though I was born in 84'.

I have Open Roads and Mudflap both. OR discounts have been much better lately than Mudflap.

Here is a snapshot of the number of drilling rigs operating. The number was diminished during the low prices during the covid days but has been improving. It’s still down from the thousand rigs operating in the years prior. There are basically enough rigs running to keep production flat, but at least it’s not declining.

A beautiful visual that clearly shows the number of rigs decreased precipitously PRIOR to 2021 and has been increasing since - counter what many believe to be true. General comment to BITOG, this is not a political statement either but to deny this simple fact would be a political statement.
