With sharply rising fuel costs (obviously no politics here, less Admin wrath...) I'm seriously enjoying the stable and low E85 ethanol prices. Here in San Diego, Top Tier 91 octane is often over $6/gal. I don't think the E85 price has budged and for my last fill was around $2.92/gal. Anyway, you can save money and have more power. Let's get down to brass tacks.
Through original algorithms, based on published, peer reviewed, test data from large fuel suppliers, OEMs and Universities, I've cracked the octane blending problem.
Most calculators out there only provide a blend to a EtOH % goal (that is a straightforward mathematical problem). There are a few esoteric web sites and even a couple of calculators out there that claim to calculate blends to an octane goal and they are all fundamentally flawed and incorrect. Often times they are really flawed/incorrect. What you engine actually senses and needs for a given tune is actually an octane specification.

For me personally, I run 91, 93 and 98 octane tunes. I have switched to a blend of E85, again still less than $3/gal here, with 87 octane. Previously, I was blending E85 with 91. But now with price changes, I have switched to 87.
Before the current price hikes, my 91 + E85 blend, getting me to 98 octane, was very close to a wash in the critical $/mile characteristic (lower cost per fill up but again worse mpg). Now however, there is definitely $$ to be saved. The calculator plays an important role here because it allows you many different approaches (costs) to get to a desired octane.
This is a paid App. I bet with current prices, you could pay for is easily in a month of blending with some EtOH.
- Ethanol does not harm (clog, "gum up", etc.) any modern engine made in the last 25 years or so. Prior to that some fuel system seals could be degraded by high ethanol (EtOH) content.
- EtOH adds octane, increases knock resistance, and cools more (than gosoline) through evaporation in the combustion chamber and your rig will run more timing to develop more power when it senses higher octane fuel. In fact, at least in the Raptor, 93 octane is required to make the factory specified hp. I think it is the same in the 2.3 and/or 2.7.
- EtOH does contain less energy per volume so mpg is less, offsetting some of the cost advantage of it.
- What your engine, especially a tuned engine needs, is a specific octane level, NOT a specific %EtOH. Unfortunately, most tuners specify %EtOH (when above 93 octane) since there has never (until just recently) been a way to accurately blend to a desired octane level.
