wheres hankL when you need to him to explain the octane again??? i had not problems runnin the 110 racing fuel it was pretty sweet although i wouldnt run it all the time just a tank every now and again it was interesting but 5 bucks a gallon

 

Not to start a war on politics or any of that ****... I think all the gas comes from the same place. I think that it is just one big mind f***. If there really wasa differance in companies, then you would see that they would have price battles, dropping the overall cost, and more bashing advertisment between companies on TV. I wonder how much Coke and Pepsi spend on competing against each other compared to any of the oil companies. And any of the ads really don't bash each other like other competing companies do (such as cell phone companies, car companies, oranything else for that matter). Just my observation.

 

FFMed you do have a point. I have run Chevron and then ran circle K gas and did not see any difference.

 

Is that what he had on there before. He's blocked, got bored reading hisangry one sided opinions. Yeah, opinions are like ********, everyone has one. But this is America, and I don't have to listen to him, just like no one has to listen to me. Sorry if that offends anyone but oh well.

 

Oh, and that web site took me like 20 seconds to look up... I think I just googled "gasoline compound" or something like that... there is about a million hits on that. That just happened to be the first one I clicked on.

 

OOOOHHH!!! Somebody referred the same site as you did!!! Are you sure you aren't brothers? LOL J/K

Seriously though, I just looked in the manual and it does recommend 89 but 87 if you don't have problems. It also recommends not burning high-octane as that could be dangerous to the engine.

FFmedic- I have read that there is quite a bit of difference between brands because all those additives are the only thing they can use to seperate themselves in the marketing. I'll try to find thelinks but honestly, I think burning a quality gas vice a higher octane is the most important thing we could do.

 

i have had no problems with higher octane gases which i use 90% of the time and FFmedic i seem to remember good ol' hankL saying something blah blah how higher octance fuels burn slower blah blah and which is bad and why you shouldnt use it blah blah you know what i am getting at

 

I have an 04 Hemi Quad Cab 4x4 ThunderRoad and I use 87 all the time. No problem. I tired hitest once but my mileaged dropped so I went back to good old 87. Been getting 15/17 for GAS MILEAGE THIS SUMMER.

If I remember correctly, the octane rating number indicates the resistance to anti-detonation (autoignition, also known as the anti-knock quality) of that fuel as if it contained that percentage of iso-octane (an isomer of octane, C8 H18) with the remainder heptane. This does not mean that 89 octane fuel contains 89% percent octane or iso-octane and 11% heptane, but it has the anti-knock qualities of such a fuel. In reality, most automotive (motor grade) gasoline contains iso-octane, heptane and other petrochemicals, including ethanol and other additives.

Octane ratings and the grade of fuel specified for a specific engine are mostly based upon the compression ratio of the engine, and the ambient air pressure that engine will be used in. At high altitudes, engines that require 87 octane at sea level can safely use 85 octane due to the lower amounts of air that is drawn into the cylinders; less air reduces compression in the cylinders, which deters knock.

Just think what it was like back in the day of supercharged and turbocharged multi-banked radial aircraft engines like Pratt & Whitney’s 28 cylinder, 4,363 cubic inch, 3,870 pound R-4360 Wasp Major radial engines that burned 115/145 octane gasoline to generate 21,000 teeth-rattling, heart-throbbing horsepower.

Don't put THAT in your gas tank! BTW, the 115/145 octane rating of AVGAS is not the same as the (R+M)/2 rating of motor grade gasoline (MOGAS). The 115 octane rating is for a lean mixture and the 145 is for a rich mixture and it is determined via a different testing procedure. Plus, it's a leaded fuel. They still manufacture 115/145 once a year for the air races in Reno.

 

yeah the 110 racing fueli used was leaded? is that bad?
