Gasoline in general

[Hrvstmn31]

So I have a question naturally several actually about gasoline brands,and octane content(levels?) so here it goes.
So is there any pluses to using one gasoline brand over another and since a gz250 is pretty easy to fill up to full
what would the benefit of higher octane gasoline be?

[JWR]

I'll just say this, regular will be fine.

We have one member, alanf, that will tell you what a GZ will really run on.

Buy an 87 octane from a major producer such as Shell, Chevron who will be adding a portion of Techron to their fuel. Techron or it's equivalent is a cleaner and is needed for fuels that contain alcohol. The best place for alcohol is in a glass.

High octane gas is not only unnecessary but it is meant for high compression engines (not the GZ) to prevent pre-ignition of the fuel during the compression phase, and has additives in it that make it ignite or burn slower and it will actually give you less power and worse gas mileage, and will also waste your money on the extra expense of it. The myth that higher octane fuel is better than regular is just that - an urban legend that just won't die.
If you want the best fuel, look for ethanol-free gas. And to keep your carb clean and avoid problems, every 3 or 4 tank fillups, put in 1 oz of Berryman's B12 Chemtool per gallon of fuel and you'll be fine. Just get regular 87 octane gas, no need for anything else.

mrlmd1 pretty much said it all. I'll second what he said. In our society everyone seems to think a higher number is a better quality, but when it comes to octane ratings that is not necessarily true. Think about what they used to put in gasoline to raise the octane number, lead, not exactly a combustible substance.

Now, having said that, if you have a very high compression engine, which the GZ does NOT have, then a low octane fuel is not what you want to use, because it is much more volatile and it will explode before the spark plug fires just from the high compression. That might not sound bad, but when it does this it explodes before the piston reaches the top of the stroke and the explosion actually wants to push the piston back the wrong direction. That's called pre-detonation and it is bad for your engine, causes that "knocking" or "pinging" sound you've probably heard in other engines and can actually cause a lot of damage if it is bad enough.

Since the GZ is not a high compression engine, if you put high octane fuel in it all you've accomplished is lightening your bank account while supplying a lower energy fuel to your engine and probably reducing your gas mileage a little to boot.

Years ago, it was often true that only the high octane gas had "cleaners" added to the mix, but current legislation in the U.S.A. requires all gasoline to have at least a minimum amount of these cleaning additives in them. If you need more than what's in the fuel already, buy it at the auto parts store and add it yourself.

That. Is. Awesome.

Honestly, all gas comes from the same place. There are only a handful of producers in this country. The places that offer fuel at lower prices generally have blended mixes and the sources all have different ages. There is really no difference between the additive packages from one brand to another. There are some proprietary additives added directly to the pure sources from the big companies, (ie; Chevron/Shell/younameit) so that they can claim that their gas is different from the competitors. But gas is gas.

If you are lucky enough to have a local station that sources 100% gasoline (ie; not E10 or gasoline that contains a certain percentage of ethanol or some other oxygenate) then buy that. To see if one of those stations is near you, you can check this website: http://pure-gas.org/

You have to be careful though. Just because a station advertises that it's gas is 100% ethanol free does not mean that it is. The quickest test is to ask an attendant where their gas comes from. Most of them will say "Well, it's Chevron gas, which is ethanol free." This is false. Chevron does no produce or distribute ethanol free fuel. There are testing kits, if you really care about it. Even ethanol free fuel will contain cleaners, but it's always a good idea, in a vehicle and an engine as picky with the carb as the GZ is, to add an aftermarket cleaner every couple of tank fulls.

Lots of people like Berrymans. It's strong, but cheaper than Seafoam (like 1/3 the price) and does the same thing. I personally prefer Marvel Mystery Oil. Why? Honestly, just because it smells like cherry peppermint and it's a nice scent to have coming out of the engine every now and then. Plus, the marketing makes it look old. Old retro stuff is cool ;)

All that being said... Just buy 87. Add some cleansers every now and again. You're good.

Interesting article here about ethanol and its potential damaging effects on engines and the pocket!:

You guys are just now getting diluted fuel? I thought it was everywhere...

Anyway, the article's point is spot on. Ethanol, as a fuel, contains fewer BTUs per gallon. There simply isn't the same amount of energy in ethanol as there is in gasoline. And replacing 10% of the energy from a gallon of fuel with a weaker substitute results in less power and ultimately fewer miles per gallon at the same time. It's also slightly more expensive. So, pay more for a fuel that doesn't go as far and doesn't give the same amount of "umph"?.... What the hell?

I'm all for clean exhaust and emissions too, but not at the expense of fuel economy and increased prices... I can at least see why we did it in our country, as we were giving our farmers subsidies and paying them money to grow this stuff. However, even that was a double sided sword, because the type of corn grown strictly for fuel purposes isn't even edible by cattle, we we were essentially paying them to grow fuel, not even a backup food source.

The ethanol experiment in the US is well documented as being generally a failure... The system they have in Brazil, where I believe 80-90% of the countries fuel comes from sugar cane, makes sense, because it is viable to their market, their pocket books and their population size. But to use the best farm land in the world to make shitty ethanol additives and fuels just doesn't make sense... Why don't we just subsidize regular farm products, if we want to give people incentives to farm?... It blows my mind.

Awesome thanks for the info now does anyone have link towards what exactly Seafoam or Berryman's B-12 Chemtool and Marvel Mystery Oil is and what there uses are. Or should I make a new post?

This article (from one of the reactions to the British article) shows that ethanol production cannot even be called "sustainable":
http://www.news.cornell.edu/stories/july05/ethanol.toocostly.ssl.html

I'm starting to wonder what the purpose is of all the scamming. First MTBE in our gas, then ethanol.

Jon also thanks for the 'good gas' station site, but in Maryland they only sell good gas on the Eastern Shore.
Here, it's too close to DC.... :retard:

Berrymans b12 & SeaFoam are the two most popular ones to use.

Well crap they all look good damn you capitalism.

[mrlmd1]

Berryman's is the best for carb cleaning and keeping it clean and is 1/3 the price of Seafoam (about$3 as opposed to $10), Seafoam was also recommended as a fuel stabilizer but Stabil and Starbrite and related products labeled as such are better, But Jonathan uses and likes MMO, so you pay your money and you take your choice. Just use one in the recommended dose of 1 oz/gal of gas every 3 or 4 tankfulls and you won't have any carb issues.

Over here, I can't get carb cleaner, so I use a "fuel additive". Works fine, and is around the equivalent of $1 a bottle.

[Fawlty]

Alan. I use this from Alcampo, which seems to work well, but I think I paid about 5 Euros. Your is cheap, where did you buy it?

[alantf]

Alcampo too. Like you, the stuff I normally use is around €5 or €6, but this was in the euro sale, so I got the last half a dozen bottles (true to form, Alcampo have never got any more) and it's just as good as their home brand.
