My friend does this with a motorcycle, to help 'clean out' the engine?

No my car does not require it and the higher octane will not clean system.

This question is as volatile as bringing up religion or politics. Everyone has a passionate opinion.
In my opinion, you only get out of something what you put into it. Garbage in, garbage out. I've only used Amoco Premium for about 20 years now in all of my cars, and they're always lively, smooth-running and problem-free. I did this initially to correct rough running in my two cars back then, and this fixed their problem. My daily-driver Ranger has 231,000 miles on it, and is as smooth and quiet as when it was new. I would drive it coast-to-coast without batting an eye.
*From what I understand*, and based on research, not just brainwashing from dad & grandpa, high-octane "Premium" fuel has a combination of benefits to it...
1 It is filtered to a much higher degree to remove more impurities in the fuel [eg: low octane fuel is dirty, and the result will be caked-on deposits inside your engine after time]
2 Premium fuels, especially from the bigger mfr's, will have much more detergent in them than does regular unleaded, therefore capable of cleaning a dirty engine, but a single tank of Premium won't cure years of build up on valves and in injectors.
I'd suggest using a good quality Premium [BP, Shell, etc] at least on occasion to help keep your engine cleaner and get better performance, mileage and reliability from it. Car nuts and car magazines alike also swear by Chevron's Techron Fuel System Cleaner which, in their opinion, is the only additive that actually works and makes an improvement in your engine.
If your engine REQUIRES Premium fuel, you should always use it. The label on the gas door will tell you which fuel grade is required for that engine.
Do you own research before accepting generations-old hearsay.
Good luck~

Only use if your vehicle calls for that octane. Premium gas will burn hotter and will eventually scorch the pistons, valves, etc. if your engine is not made for this grade of gasoline.

LOL. lots of opinions. One thing - Premium does NOT burn hotter - it burns cooler. The extra octane prevents pre-detonation by reducing the gasolines volatility. Running premium can actually cause carbon buildup, which is why (I believe) they put the extra detergents in there in the first place.

It can help to clean out the engine but it can also cause problems. A lot of places where you buy gas at don't sell a lot of premium gas so it just sits in the tanks and can almost go bad. If you are unlucky enough to get this gas it will cause a lot of problems. If it's clean then it should be ok every 4th tank or so.

NO. the sole distinction is the octane score (and the cost). in the journey that your automobile in basic terms demands time-honored, do not bypass spent extra money for not something. in the journey that your automobile demands top rate, do not placed time-honored in it or your paying for a sparkling engine (little better than gasoline precise now)

HIgh octane gasoline does not clean better. It is more resistant to pre-detonation. That is all. It's needed in engines with high compression ratios and engines that have turbochargers or superchargers. That's it.
It's not "better".. it's just has different properties. Your friend is wasting money.
A quote from Wikipedia:
"Higher octane ratings correlate to higher activation energies. Activation energy is the amount of energy necessary to start a chemical reaction. Since higher octane fuels have higher activation energies, it is less likely that a given compression will cause knocking. (Note that it is the absolute pressure (compression) in the combustion chamber which is important - not the compression ratio. The compression ratio only governs the maximum compression that can be achieved).
It might seem odd that fuels with higher octane ratings burn less easily, yet are popularly thought of as more powerful. The misunderstanding is caused by confusing the ability of the fuel to resist compression detonation (pre-ignition = engine knock) as opposed to the ability of the fuel to burn (combustion). However, premium grades of petrol often contain more energy per litre due to the composition of the fuel as well as increased octane.

Super unleaded gas is more pure and burns hotter then the plus or regular. It is a good idea to run plus in it and put super in it at least once a month to burn the crap that builds up it your injecters and other fuels systems.

As I recall my motorcycle required the higher octane due to the compression ratio. If the bike doesn't call for it, then don't do it. You aren't cleaning out anything.

i have to use premium in a few of my vehicles
you can use it it if you dont have to, but most of the time its because regular has a lot more impurities in the gas and premium will help it not gum up when it sits

yep indeed but if combined with carb cleaner then a potent cleaning mix will burn and get rid of powerclogging debris.
