I have to disagree with your statement.
First off, Premium fuel has extra cleaners in it. So, not only does it burn better, consistent and cleaner than 87 octane which is very dirty I might add, it has additional cleaners that are added by manufacturer so it runs MUCH cleaner than 87oct.
Now, if you trade your vehicle in every 36kmi then no worries and you probably wont notice much if any difference at all. It's when the engine gets up over 50k you will certainly start to notice!
So, for the simple fact that Premium fuels are in fact premium, it's not wasting money. Your just keeping your fuel system and heads much cleaner which is actually preventative maintenance.
2nd. Since it burns cleaner, your MPG's can actually improve. I doubt it's noticeable enough to make it worth the extra expense if thats the only reason for using premium, but it will improve mileage because it burns cleaner and will not cause detonation which is basically your engine working harder to go the same distance. Cleaner engine ports flow better and will yield more power than chambers full of carbon and gunk.
Next, the Hemi is recommended to have 89oct because of the very shallow ringlands that are used for the pistons. They mimic'd NASCAR style because they are very high up on the piston. They are very thin. Excessive detonation can break this area apart and obviously cause some major damage. In fact it has on the older model Hemi's 03-08's with higher mileage. I'm pretty sure your 2014 uses the same style pistons as the older one's. I realize they say 87 is acceptable but it's definitely not preferred.
Lastly, you must drive regularly or I would stay away from 87oct. Especially if you have 10% ethanol blend like we do here in NYS. Ethanol degrades gasoline much quicker. In 3 weeks time, that 87 octane will become something like 84oct. It's crazy how fast gasoline will degrade with the ethanol mixed in. I know sealed tanks will increase the lifespan, but I choose 93Oct for my 91oct tune. My truck sits a lot. Matter of fact, my truck was parked in October and didn't move until April.

Dirtydog....you need to try to convince the 06, that I just sold, of your gas theory. I stand by my statement since my 06 had 114,000 miles on it when I sold it and it ran on a steady diet of 87 the whole time. Have also never had 87 or any other ethanol fuel degrade as you put it. It sits in my lawn mower all winter without any additives and starts and runs just fine every spring. If you want to pay 35 cents a gallon for some detergent go right ahead. I said you are wasting your money running premium in our trucks...never ever mentioned any detergents just that it doesn't run any better or give better mileage. Also premium fuel burns slower, not better, than what our trucks were designed for. The slower burn is to help eliminate knock in high compression engines that are designed for premium. Our trucks aren't designed for it and don't need it, and will run way over the 50 thousand mile benchmark you tried to establish in your post, running 87 octane, without problems. I've read on HERE of Hemis going over 200,000 miles running 87 octane...and I wholeheartedly believe it

I also have replaced two carburetors on my snow blower because of it. The first time was when it sat for it's first summer in my shed. The small engine repair shop i use showed me the carb jets had literally melted. Replaced the carb and the SAME thing happened a year later. Since then i run it dry with a tank full of Startron and i have had no issues since. That same shop pointed out how his business has gone through the roof ever since all this ethanol nonsense started up. Older engines with fewer plastic fuels system parts typically have less issues. But almost anything made with plastic fuel system parts will not last.
So while you may have been lucky enough to have no issues simply because you don't keep fuel around long, i assure you that is not proof that the whole issue is a myth. Your implication is that since you have had no issues that the problem must be false?. That's like saying anything that has never happened to you personally is simply a myth.
Reality proves you wrong quite easily. Their are plenty of articles from reputable sources that confirm this not to mention first hand facts. Here is a great article worth a read:http://www.popularmechanics.com/cars...-damage-engine

You're right, we do disagree, but I don't take it personally like you seem to. I stated what my truck had done..no more no less. And the manual states 87 and 89 are both accepted, and both 87 and 89 around here contain 10% ethanol, as well as 93 octane contains 10% ethanol also

Ethanol wreaking havoc on fuel when it sits for a long time is no myth. Every since they started adding all the ethanol to fuels we have had nothing but issues with gas powered tools in the firehouse and with my training company. We have several saws that NEVER had issues start having starting and stalling issues since we had to switch to Ethanol fuels. Several guys i work with have side businesses doing landscaping and see the same issue with fuel that sits too long. The solution has been to use products like Stihl's MotoMix fuel which uses AV gas (NO Ethanol!) to eliminate the issue.

My implication was that "I" had not had any problems with ethanol gas and never said it was a myth. Your implication is that everyone has problems with it, and that's just not the case. What has happened to you might not have happened to someone else. My mower sits for 6 months at a time, fueled and no additives, and never has the problems you or Dirty are talking about. So we are just going to have to learn to agree to disagree on this matter. I'm good with that if you are

Ethanol is not a concern in the modern automotive engines but the small engines have all the issues. Our trucks are designed to easily handle 20% or more ethanol. The difference is fuel components being manufactured so they don't corrode from the ethanol. The small engines never made the change so the are still susceptible.

The issue is not just corrosion. We are seeing plastic carb jets and floats MELTED when using new fuel. Engines that never had issues until this new fuel came out are now having way too many issues. Prior to Ethanol we would leave fuel in our snow blowers year round. Never had any issues even when they sat unstarted for months. Now if they sit for a few months they wont start and they often need carb rebuilds. So long as we run them dry at the end of the season we have no problems. As i mentioned with our 2 stroke stuff we simply use AV gas and the problem is gone. Because the Ethanol is.
Also, I would not leave gas in anything all winter and think all is well. With zero ethanol it's going to cause issues. Every manual of every snowblower has always said to empty the tank or run it dry before storing.

Uhhh, that's basically what I just said; small engines are greatly effected due to their design, but modern automotive engines are not susceptible.

I also put stabilizer in my truck over the winter because I rarely drive it.
