Octane Reqirements
Will Spyder's run well on 87 or is their appetite for expensive preminum?

This time of year if you can find non-ethanol 87 they'll run just fine. Don't know about ethanol though.

I run nothing but preimum (92 0ctane)..............if you check in the manual, I believe that it suggests 90 octane minimum

The manual says use Premium unleaded fuel for optimum performance. Recommends 91 octane but does state 87 octane minimum.

They'll run on 87 just fine; the computer will do whatever is necessary to prevent the poor fuel quality from damaging the engine. But... giveing your bike the good stuff (Better stuff??), will probably increase it's performance potential and get you better fuel economy; the 991 engines are designed and tuned for at least 91 octane...

I, in the past, ran mostly premium. There were some occassions that I ran lower. I decided with my 2013 to follow what is recommended and run only premium.
On a side note there is a move in the Flarda Legislature to ban ehtanol in our gas. Hopefully our representatives will have the.....the.....(well you get my drift) to pass this law.

Always 93 octane in mine.

I've always run premium in both my Harley and now my Spyder. As the sales rep said "it's only a bit extra to use the good stuff and it's not like you're filling a 20 gallon tank."

Being in Iowa it seems only BP offers high enough octane. You will notice the difference.

I've always run 93 as well...
Here's why.
What's the difference in price; 25 cents a gallon? on a four gallon re-fuel; that's only a buck!
For an extra buck per fill-up; I'll give the bike what they wanted it to have. I can save that buck by drinking my coffee at home...

Octane Reqirements
I fully agree - it's worth the extra cost.
Also, with 93 octane, much less chance for spark knock or pre-detonation. Even if the engine has a knock sensor (don't know if it does) which would retard the spark timing to compensate. But why would I want to be running the engine in that sort of mode... walking the line on spark knock and with reduced performance?
I'll spend the extra buck per tank every time.

RT-S PE#0031
The GS/RS Spyders were designed for the lower octane gas. The RT & I believe all 2013 Spyders call for the higher octane. The higher octane level does not mean a better quality of fuel, just a higher octane content to resolve preignition issues with higher compression engines such as the RTs have (& all 2013's, I beieve). The pre-2013 GS/RS Spyders have lower compression engines and do NOT require the extra octane. If you ride a non-RT Spyder, the only benifit of spending more for higher octane is your peace of mind. It does not help your Spyder.

also. I believe the extra fuel additive cleaners that come with higher octane fuel help keep the throttle parts running at peak[I know others don't agree, some saying all octane levels are the same] my experience tells me otherwise.

Through 2012, the recommendation for the GS or RS was 87 octane (regular) and the recommendation for the RT was 91 octane (premium). Performance on an RT will be degraded with 87 octane, but it will usually adjust and operate there. I'm not sure about the 2013 recommendations, since the RS has apparently adopted the RT engine.

RT's take premium and GS/RS take regular. Using premium in a GS/RS is waste of money. The believe that premium gas is better, cleaner, burns better, gives more power is marketing hype. More cleaning agent then is needed does not improve performance. Adding stuff that does not burn very well does not increase power and gas mileage. Increasing compression thus requiring gas that does not ignite as easy, increases power and gas mileage.

It seems as though most feel that running regular in the RSS is adaquite so my responce to this is if you have any performance mods on your Spyder running the premium can only increase performance infact most fuel controlers state that the use of premium should be used.
My Harley with mods and my Lincoln LS with mods require premium so i guess running the good stuff in my Spyder with mods wouldent hurt either thats all i will run in my vehicles.

There are as many opinions about fuel octane as there are people willing to talk about it.
If the recommended 90 octane (for an RT) is not readily available in your area, you can use 87 octane. 87 octane is the minimum recommended octane for an RT. You may find your Spyder will run just fine with it. Others may not though.
BRP recommends the following (as per my 2011 RT manual):
Fuel Recommendation: Use unleaded gasoline or oxygenated fuel containing no more than 10% ethanol or methanol.
The gasoline used must meet the following octane number:
FUEL OCTANE RATING INSIDE NORTH AMERICA
Recommended 91 (RON + MON)/2)
Minimum 87 (RON + MON)/2)
Use premium unleaded fuel for optimum engine performance.
FUEL OCTANE RATING OUTSIDE NORTH AMERICA
Recommended 95 RON
Minimum 92 RON
Use premium unleaded fuel for optimum engine performance.
Other fuel can degrade vehicle performance and damage critical parts in the fuel system and engine.
There is a lot of information online to learn more about the importance of using the proper fuel for an engine. You may find it interesting to learn just how it affects an engine and its performance. There are a lot of myths out there...
In addition; some believe a 90 octane fuel is better than an 87 octane fuel. That is simply a misunderstanding and is not true. It is just a different fuel designed for a specific application. You will want to use fuel within the range recommended by the manufacturer specific to the engine's requirements for optimal performance, fuel consumption, and to help prevent damage (caused by knocking or pre-detonation of the fuel). (They just don't pull their recommendation out of the air. There is a reason for it.)
A Spyder is an expensive vehicle... so the choice is yours on what to use. Personally, I use 90+ octane (without ethanol) whenever possible; but will use as low as 87 when it is all there is (again avoiding ethanol whenever possible). I notice a performance difference in doing so.
Good luck on your search in getting your Spyder...

I ran each octane level through my RT(s) and calculated a cost per mile since I experienced lower mileage on lower octane.. For both my units the most economical choice was 89 octane - the boost in mileage over the 87 more than compensated for the extra cost..

Hmmm... I like having choices. In Iowa 89 Octane is the cheapest. Right now running $3.04 a gallon.

You have an advantage living close to CR as BP is more readily to be found. I survive on Kwik-Star a chain out of LaCrosse, Wosconsin where the highest they carry is just 92 octane at least in my area. By the way what kind of fuel mileage should I expect to see?

You are going to find a few opinions and suggestions on this subject.
I currently have a 2010 RTS and a 2011 RT--A & C
We do not have ethanol added in AK. We can usually buy 87, 88, or 90 octane here.
I run 90 octane all the time now in both 's. I do notice a difference in performance if I am forced to use a lower octane. The just does not seem as "peppy" to me. The difference is 20 cents per gallon higher than the lowest grade.
I also ran 90 octane in my 2008 GS and the 2009 RS with the same results.

There was a documentary done by CBC TV in Canada on the difference between regular gas(87), and premium(91-93). Oil companies are claiming cleaner burning and of course better fuel economy with higher octane fuels. In independent lab tests the additives in both fuels were the same so a cleaner burning fuel is not possible. There was a possible slight increase in fuel economy however for the additional cost it more than evened out. Bottom line is, use what you feel is right for you and your vehicle.

We use 87 octane fuel and look for ethanol blends where available. Ethanol is a very clean burning and renewable fuel as well as helps to disperse moisture in the fuel system. IMO, I hope we, meaning our governments, lean toward more ethanol in gasoline simply for the fact that it is renewable and can be made out of the crops grown on our farms.
Ok, the speech is over and I am stepping off my soapbox!
