93+ always. Runs quiet, more snap on the throttle. On my third tankful now and I won't put lawnmower gas in it. Got forced into 87 once on my 2010 and paid for it in the end. Not thinking, started it up and pulled it outto the end of my drive to wash. Drove it back into the garage when I was finished. Hopped on the next day to go for some errands, started up on one cylinder. Fouled plug. Never had that problem with good gas.

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

You may have gotten some bad gas but that's not 87's fault. I ran 87 in my 2010 for 3 years and was getting 36-38 MPG with no ill effects.
I usually go to Sunoco in Canal. I put 87 in my lawnmower, never in the Spyder. 93 or 94 if I can find it. Rode to Maine last summer and could not find any station with more than 91. And ended up with a fouled plug on my 2010. I think the second throttle body was crapping out too. Hope the 14 does better..

My owner's manual for 2012 RT says 91 for "optimum performance" and 87 "minimum". As others have stated higher octane means less explosive under compression not higher quality. The air fuel mixture needs to burn rapidly but not explode and possibly blow the top of piston out. Modern engines have "knock detection" that delays timing if knock is detected. In the old days if you heard knock in auto engines on acceleration, you knew it was time to retard the timing a little.

ENGINE DESIGN
...:bdh::bdh:I'm sorry but....If your ENGINE is not designed to use 89 + OCTANE fuel it is not benefiting from using any higher octane than what it is designed for, and your Spyder is not going FASTER OR SMOOTHER ETC ......................And anyone out there who feels this is false PLEASE provide ACTUAL proof....Non of this seat of the pants nonsense ..............................Because someone who just spent $ 2000 for a 25 HP increase on a 300 HP engine and tells you HE / SHE / IT can feel it is just plain full of ( BLEEP )........JMHO.....Mike

Recommended Fuel
Use premium unleaded gasoline with
an AKI (RON+MON)/2 octane rating of
91, or an RON octane rating of 95
^^^^ 2014's Book states the above - Never state the minimum anymore like they used to. Must been some research! :chat:

Sorry, the 2013 and later engines are DESIGNED to run on 91 or better. Running regular causes a severe performance loss as the knock sensors tell the ECM to drastically cut ignition timing to protect the engine. Its significant, 20% or more. Use the required fuel in your bike.

Sorry Mike; they're actually recommending 91 octane... and it's right in the owner's manual.
Recommended FuelUse premium unleaded gasoline with
an AKI (RON+MON)/2 octane rating of
91, or an RON octane rating of 95.
NOTICE
Never experiment with
other fuels. Engine or fuel system
damages may occur with the use of
an inadequate fuel.
Page 56. :thumbup:I don't think that they'd do that just to screw around with us... :shocked:
Since I can't find 91; I give mine 93 at every fill-up!
Now; your GS (?) WAS designed to run 87... It ran a lower compression ratio than the newer 991 series engines...

You spend 30K for a bike and complain about the few pennies difference between 87 and 93:banghead: Feed the beast what she wants and what is recommended. Your Spyder will perform better, JMHO of course....

OMG someone with common sense and brains, ...and you are correct this post will offend and tick some off :roflblack::roflblack::roflblack::roflblack::roflblack:, But not ME :thumbup::thumbup::thumbup::thumbup::thumbup::thumbup::thumbup::thumbup::thumbup::thumbup::thumbup::thumbup:MikeWith running the risk of ticking some people off...
You pay $20 to $30k for a vehicle and consider using something other than what the manufacturer (engineers) recommend? :banghead:
There are reasons why fuel octane ranges are recommended -- however, having said that, I'll bet a case of beer there will be someone post on this thread with a long list of reasons why they know best and use whatever they want in their Spyder, and that it is better than the manufacturer recommends. :roflblack: Just another reason I do not buy used vehicles.
Most people do not even understand what octane ratings mean. Some believe the higher the octane the better the fuel; which cannot be any further from the truth.
Octane has nothing to do with the quality of the fuel; as so many uninformed seem to believe. If it did then everyone would use "rocket-fuel" in their vehicles.
In the most of layman's terms, octane relates to the "burn-rate" of the fuel; and various engines require specific burn-rates to work properly as designed to get the most from the engine and prevent damage over the long-term.
Use what the manual says to use... there is a reason they provide the suggestion.
Again... another reason I do not buy used vehicles.
Sorry if this ticks anyone off or offends them...

jcthorne, I'm sorry also..............to tell you that you need to read past ( 89 + octane ) in my post............to understand what I actually said ....& the same goes for Bob Denman........................just tryin to keep things straight here .......Mike :thumbup:

Cheap fuel? It's a personal choice.
Something to think about.
The gasoline that is sold at your local gas station must conform to an EPA-mandated minimum level of “detergents” to help prevent and reduce the build-up of fuel related carbon deposits that both increase exhaust emissions and reduce engine performance.
Unfortunately, all the various blends and brands of gasoline are not created equal, plus some low-quality gasoline brands have additive packages that are not strong enough to keep the engine deposits under control.
Several of the world’s top automakers worked together to establish a higher “Top Tier” standard for gasoline that would contain a higher level of deposit control additives. Many gasoline retailers sell gasoline with a lower quality additive package, so unless you are always using a gasoline that conforms to “Top Tier” gasoline standards, it would be a good idea to use a fuel system cleaning chemical on a standard maintenance schedule.
Having seen several Spyder engines in various states of disassembly. All of them shared one thing in common. Lots of carbon build up....some were very low mileage motors too.
fwiw

I have put 93 octane in my '13 ST since new off the showroom floor. I've never had any problems with it, but could the higher octane be the reason there is a strong smell of gas after a ride of 100 miles or more? Ive not found a leak or noticed any less fuel in the bike after I've parked it and come back to check later.

Under the right conditions
All pre 14's may emit fuel vapor smell.
There are numerous posts on the subject. Search gas/fuel smell.
