Gas Premium Octane

I have a BMW and I burn premium, as directed as I do on my bike, but on the BMW forum, someone pointed out that in 3rd world counties their gas is rarely premium and the cars adjust and run fine. So I would agree the computer figures it out and adjust. Burn what you are comfortable with. Since we use to pay $4-$5 for premium and now its $2.50 who cares.
 
"I asked a simple question, my manual shows 91 octane, and I asked can I use 93 octane. Only looking for yes or no. Thank you. "


Even with a "yes, or no" question; that still leaves room for at least two differing opinions... :shocked: :banghead:

Funny:yikes:
 
Sorry

OK, I'm sorry. I should not have been a smart a$$ when a new guy had a real question. Welcome, new guy. My answer to your octane question is also a Yes.
 
Gas octane rating is a resistance to knock--pre-ignition-

Making a comparison on a dyno the 87 Octane will produce more rwhp than 89 or 91 or 93. Avoiding pre-igniton is the goal. I have burn the valve seats on two 1298 engines Suzuki Hayabusa running NOS- One at 193.5 & the other at 197.3 mph at the end of a one mile track. Both time I was running C-16 which has 117 octane rating. My problems ocurred because I didn't back out 3-4 degrees of timing at 10K rpm. I have seen some fast bikes running 87 octane with corrected-(retarded top end timing) I've also seen the ethanol 87 octane run without any problems except worse gas mpg. Not sure of the $ savings between various octane ratings but the savings will be less than an engine rebuild. I'm guessing 89 octane would run without any problems to the 1330 engine--maybe 87 octane would work also. I've been running 93 octane for the 1st 1200 miles & will switch to 89 shortly. I really love my F3's but it wasn't designed to be a rocket. All my life I've wanted just a little more power than I had---now with 343 rwhp & 212#lb on the 525# turbo hayabusa I'm regressing--no more rwhp needed :-)

Wow you call me a new guy, but I have 127 posting versus your 137 posting, I guess you are correct I am the new guy.. Now that is funny. :mad:

Here in my area we have 87, 89, and 93. I ran 93 for a long time but recently switched to 89 and seems a if my MPG has increased or at least MPT (miles per tank) has. I try to buy gas as soon as I can after the low light come on, and lately it seems as though that is around 15 - 20 miles higher than it used to be. This is all subject to my imagination of course. :D
 
Octane

My opinion [what ever it's worth] the :ani29: will run just fine on either 87,89, or 93. but the most consumed gasoline [because it's the cheapest] will always be 87 octane. so I'll take the freshest gasoline in the tank which just happens to be 87 octane.
 
Akrapovic pipe without a cat bypass, only a slip on of the muffler. :)

In simple terms yes, there is no problem. Reading your signature line shows you run an Akrapovic pipe. Are you running the cat bypass also? If so, you may find the 93 will let the timing not retard and give you more bottom to mid performance.


In regards to reading these other posts, many have mentioned pre ignition. Octane is the fuels ability to have a controlled burn under pressure. If the fuel explodes rather than burns you have detonation, this is bad if not controlled. Pre ignition is different from detonation. Pre ignition is when something other than the spark plug begins the burning of the fuel. Often it is blamed on hot exhaust valve edges, carbon or a sharp cross section in the combustion chamber, even an improper spark plug heat range.

Depending upon various design factors, unless an engine has the ability to operate on higher octane efficiently, the higher octane can produce less power. However if the engine design can "tune" itself, additional performance may be gained.

We have always run 93 with Yamalube Fuel Med Rx in our 14 RTs. Stock pipe with a cat bypass.

I read my manual and it shows the use of 91 octane. In my area the gas pumps are showing 87 - 89 or 93. I guess 93 octane is okay form my 2015 RTS?

I have NOT seen any difference running 91 octane vs. 87 octane other than the costs?? My buddy runs ONLY 91 octane in his Spyder and DOES NOT get any better mileage or performance than I do.

Always the same groups.

Higher octane is always better (not true - depends on the vehicle).
Run the cheapest gas you can find.
My Spyder runs just fine on low octane fuel.
The Spyder runs best on higher octane.

You can probably run your Spyder just fine on octane lower than 86. But there is a difference between running just fine and running at peak efficiency. And that, I think, is where all the disparity comes in.

Your Spyder is designed to run best on a higher octane fuel. Not only do the numbers (compression ratio, etc.), indicate this. But I've proved it to myself with extensive octane testing.

But! Your Spyder is also designed to run well on lower octane fuels by retarding the ignition timing. This reduces power, efficiency and fuel mileage. The warmer the climate, the greater the difference. But since most people don't notice the difference, there is an illusion of getting the same results with a lower priced fuel.

I'd use the 93 octane if I could get it.
 
Hi,
50 cents more per gallon for 93 where I live. .50 x 6 = 3.00. My baby drinks top shelf. I'm not skimping on pennies when I have dollars invested. MTC. Thanks!!
