EcoBoosts, Fuel, Octane, Ethanol and Tuning...

[Plati]

Balderdash! Ethanol is an octane enhancer. It's use began after MTBE was banned. Stations in my area sell 93 octane with 10% ethanol. I use it in my Lincoln 32V V8. Octane sole purpose in anti spark knock. Lack of spark knock allows maximum timing(max power). 93 octane is 93, no matter what fuel. There is a push against future E15 sales. The current E10 mandate, is considered the highest that should be run. Ethanol absorbs water. Oil water/fuel mixing is a bad thing.

You are wrong about the Balderdash part. That's ok. Not everyone knows and understands everything. Combustion Engineering is a fairly complicated topic. If you have the means and are interested, take some time to try to understand what the point is. Thats worked for me in the past. It's kind of interesting when you dig into topics and find out they are 5 layers deep. Another thing thats funny is (for older folks) ... who learnt or were taught things as a youth and haven't kept up with the times and new info. I've been caught by that!

Why do open wheel racing cars use almost pure Ethanol?
See if you can find an answer to that.
Homework assignment!!

My friend uses ethanol in his vintage 440 drag strip car. My brother in law used it in his drag boat. They buy it in 55 gal drums. The main reason for using it is price. !00+ octane race fuel is almost $10/gal. Ethanol is around 110 octane and around $2/gal.

Jeep just announced the V8(6.4l 392) is back in the Wrangler. They choose today, the day the Bronco is released. Wanna bet Ford puts the V8 in the Expedition and future Bronco. Hey Lokiwolf please post a video, actually pumping E50 in your 2020(that only allows only E15). Then drive it 20mi and lets see if you get a CEL. PRACTICE WHAT YOU PREACH.

The new Bronco’s got the EcoBoost today. Jeep can keep the 6.4

I know call on me teacher!

Higher compression ratios need higher octane. Alcohol fuel mixtures also cool the air charge creating a more dense air charge. Turbo engines benefit from both.

thats all fine and good but the combustion engineering properties of ethanol are not based on how much your friend or bro wants to spend on fuel.

Please don’t use Science and facts. Neither works for him. He just likes misinformation and incorrect assumptions. He will not understand, been trying for months. I refuse to try anymore.

Nice article! Look at that...science.

you probably run ethanol in your snowmobile doing hillclimbs at Brantling

Are you talking about race cars or expeditions? You know the ones, Ford says no more than E15 max.

2.7 is available, but I’m sure you missed that looking at your 2020 Expy fuel requirements. Don’t worry it’s a V6 and runs great. Just so you don’t have to google it.

The 'new' Bronco is for ladies and beta males that prefer a 2.7l V6 to a V8 Hemi. Fozzi you need testosterone supplements.

I run Tren, way beyond what mortal men can handle. What do you drive again? Pic’s would be good. Love the cars from the 80’s. Sorry LW, it’s fun to poke the wannabe.

You V6 Expedition 'racers' are definition of wannabe. Lokiwolf wife's actually owns/drives it. Hope those cam phasers go under warranty. Then there is direct injection pump and turbo line leaks and failures. I will laugh when Ford's Expedition reboot has a V8. The used car lots will be full from the EB trade ins.

Um, ok. I didn’t know girls were into factory triple locked vehicles running 35 inch tires.... clearly I don’t understand women.

I'm not a huge off road crawler guy (yet) but would a vehicle for those purposes even NEED a big V8? I would think lean and nimble thin and raised up. Can get all the torque you want with gearing not a massive engine best suited for towing. Use the right tool for the job.

See, now this thread has officially been run off the rails.
Lets get back to its original purpose.

In terms of its octane rating, ethanol has a rating of 113. As mentioned above, fuels with a higher octane rating reduce engine knocking and perform better. Also, almost all gasoline in the US contains up to 10 percent ethanol. When you mix 10 percent 113 octane ethanol with 85 octane gasoline it increases the octane two points to the normal 87 octane most consumers use. So the higher the ethanol content, the higher the octane. The octane rating for E15 (15% ethanol) is 88 octane and E85 (85% ethanol) is 108 octane. Now this is based on 85 octane fuel. Back when I used to haul fuel I would go and fill with the 10 percent ethanol first and then add the 90 percent gasoline to get E10. The kicker is that when filling with gasoline I would load the same 87 octane that was used in non-ethanol pumps. That would make the E10 blend 89 octane on a pump labeled 87 octane. I cannot say if things have changed and it is now premixed prior to loading.

I'm sure this has already been said ...in fact I think I read a recent post that pointed out that this topic is actually "5 layers deep" ...

The primary purpose of "octane" is a RESISTANCE to combustion and is usually required by engines running hotter operating temps (which definitely includes turbos). But it CAN be frivolous ...even damage-causing to run a higher octane rated fuel in a NA-EFI powerplant. Personally, I will follow the manual and largely run 87 for my "no load" usage and will run the highest octane I can find (91 / 93) when hauling the whole family and/or towing.

RJ ...I think this is a little short-sighted. I have been highly dubious of the 2.7L and 3.5L EBs ...and with just cause. Lots of problems with 'em from inception to at least 2013, maybe even 2014. But I probably have two-dozen "cohorts" that have the 2.7L or (mostly) the 3.5L EB in their rig (usually an F-150 ...I think I'm the only one with an Expy now); and they have all been trouble-free.

I have only 1800 miles on my Expy now and about 500 miles of that was my first towing outing with our 6200# camper. This engine towed that camper with every bit of capability as my 6.6L Duramax I just let go of. If I had one major concern / complaint thus far, is I am dubious of the 10R80's longevity and heavily researching how to make that trans a more bulletproof platform. (I will be pushing max trans fluid temps quite a bit here in AZ, and would love to see something that would allow me to pull the temps down from 235-245F down to 220-230F [while climbing]).

I wouldn't of towed that load, in that kind of heat, with that low miles. It's barely broken in. The new transmission, shuts off flow to the cooler, until it reaches a certain temp. They use ULV fluid(ultra low viscosity). The thin fluid runs hotter. Ford claims this rig is capable of towing, like 9300lbs. The computer will go into limp mode, before damage is done.

RJ ...I followed all of the towing guidelines, including waiting until there was 1000 miles on the rig. It did fine ...but I at least partially agree. Not sure I would EVER try to tow more than 7000# with this Expy, even with the HD trailering package on it. But then, I've ALWAYS been a "stay under 75-80% towing capacity" type of tower. I might consider a couple of percentage points higher than that if I wasn't in the oppressive desert heat. The one thing I have to come to terms with is that I'm just going to have to slow down on steep, uphill grades. I'd be willing to bet I could easily keep the temps below 230F, if I just discipline myself to accept the required 25-35mph speeds to make that possible.
