Another gas thread....i know i know but read

[ChevyFazer]

I know there is much debate over what gas to run, and here in the states alot of folks run regular because the manual says too when regular everywhere else in the world is 91 or 93. Well, while i was cleaning and lubing my chain i noticed on the swingarm a sticker that clearly says;

Fuel: all gasoline 91 ron min

I've always put in the highest i can get at the pump... but i believe my bike (versys) also says that on the swingarm... good point about "regular US Vs. Regular everywhere else" :thumbup:

Fuel: all gasoline 91 ron min

The Octane rating you see on the pump (Pump Octane (PON)) in the US is (Research Octane(RON)+Motor Octane(MON))/2

Just in case you can't sleep here is an article that better explains the calculation. from this article you can see

RON MON PON
90 83 86.6
92 85 88.5

Therefore 91 RON is about 84 MON and 87.5 PON.

Did I mention that I was a failed Chemical Engineer ??

My bike was debadged before I bought it (no decals anywhere except for VIN sticker), but common sense tells me a 12.5:1 compression engine should run higher octane.

That being said I have and always will run premium fuel in my bike.

As a former oil company employee, who still holds stock in said oil company, I thank you for your dedication to increasing the value of my pension.

I see i just saw the 91 and assumed that was referng to premium...but either way that what i use and always will id rather pay a little extra just for.the addd benefits of a "cleaner" burn

How do you define "cleaner?"

 

[ChevyFazer]

Not leaving as many deposits left behind in the long run

Octane refers to the resistance to ignition.... diesel fuel is higher octane than gasoline.... which do you think would leave more deposits in your gasoline engine?

If the motor has pre-ignition, higher octane is required to control the start of combustion. Other than that, I can't think there is any real benefit.

Oh believe me there is plenty of benefits in the long run, its not necessary our bikes will run just fine on reg but higher octane fuel dose burn cleaner because of the detination point. Less fuel is wasted wich also makes it more efficient. The short term benefits are minimal but if you take 2 identical vehicals and run one on reg for 50,000 and another on premium then pull apart the top end you will see the difference. And i used to be a diesel mechanic and comparing diesel fuel to gasoline is like comparing gasoline to transmission fluid, they are completely different and diesels dont function the same way they use compression ignite not spark, you can litteraly fill up a diesels tank with atf and it will run....

A higher octane than required would cause no less deposits than regular grade. Octane doesn't measure ability.

Octane is a measure of resistance to ignition and nothing else, the higher the number the higher the resistance. So a 87 AKI (The octane rating used in the US which is RON+MON/2) has the same amount of energy density as 93 AKI fuel. The only difference between them is their resistance to being burnt.

By putting higher octane in a motor not designed for it you aren't helping it. And can actually create less power in the process, Testing was done by two magazines on the GSXR 600 one was on a 07 which required 87 AKI and it made LESS power on 87 than it did on premium. SuperStreeBikes did a test on the 2011 600 which recommends 90+ and they found no difference between 87,89,93.

I know what octane ratings are and know what it measures, and realize that it dosent make any more power than regular gas, but that being said nothing will change my mind about using it and its "benefits" compared to reg, ive sceen plenty of trashed injectors from people running reg in a car that was suposed to take pre, and quite a few from ones that take reg as well, and ive sceen a fare share of vehicals that had engines clean enough to eat off of and the the owners claimed they only run premium gas and top quality oils. I have yet to see a dirty anything from a engine that was only fed premium, the day that i do i might change my mind....probably not, ill probaly try to find an excuse of something else to be honest lol

Hey, no problem, been doing it for years :thumbup: My car is a modded 1998 Grand Prix GTP (supercharged), I know it needs higher octane :rockon: I've alos had experience with high compression automotive engines that need racing fuel (110 octane min). I'll admit my experience with motorcycle engine is limited, but since it only costs me about $15 to fill up the bike with premium every 4 or 5 days vs $13.80 for regular, I figure what the hell, what's an extra buck for having peace of mind? :cheer:

yamaha is trying to trick you into using the low octane stuff so you will have to buy a new engine every year

forget about the octane number, detonation point etc, the best reason to use premium gasoline is because they have more detergents in them than lower grade gasoline. The extra detergents will keep injectors and stuff cleaner without using injector cleaner. I figure the added cost of premium balances out with not having to use injector cleaner.

I believe this has been de-bunked, even by members of this community that work(ed) within the oil industry. A lower grade fuel is not "dirty" in the sense that most people often think (unless you're getting it from a terrible source!), but this is what marketing tells us: "low number bad" / "high number good!". Pre-ignition (not just relating to compression ratio) has a bearing on the proper octane for an engine, but overall it's going to be up to the engineer(s) that designed the engine to determine what octane is proper. To get the most out of any engine, many things have to be matched: octane, spark plug heat range, timing, compression. You can't run 100LL with a cold plug and expect magic. Somehow people always think though that super high octanes work some kind of voodoo inside their engines without adjusting any of those other categories, and I blame hyped up marketing for that.

It's all marketing dude...They have got you believing that "hook line and sinker"... they did their job well then.... I also own oils stock (Canadian, anyway) so thanks for buying into "more expensive is better" theme... I am way older than you and have used regular fuel in every vehicle I have own in the last 35 years... Low compression ratios, high compression ratios... carbs, fuel injection.... I have had them all... Never once had a fuel related issue, no pinging, no knocking and no gummed up anything... So keep putting that premium fuel in your vehicles... I need my retirement cottage...

Saying thanks for someone purchasing premium when you stock in company x is like saying thanks to someone buying milk if you happen to own a cow. Even if the purchase was from company x there is a tiny tiny coralation between the price of premium vs regular (about .05¢ a gallon) and the rest of the markup goes to the station

The new oil thread is a gas thread.

The difference is the brand, Chevron for example has Techtron cleaner in the fuel, where as Sam Club most likely doesn't. That is what keeps a motor cleaner vs octane.

Oh, I also own cellular network stock (still Canadian, mind you)... but thanks for using your cell phone too...:BLAA:

I own Trans Canada Corp stock... they are working on the Keystone pipeline to supply oil from Alberta, Canada to Texas... So indirecty, you are still "will be" putting money in my pocket using gasloline refined from heavy crude sent to the US via the Keystone pipline (yes, of course when it come online)...
