Hi all I'm wondering what kind of gas dose the spyder take??? I have a 2012 RT what gas is recommended??

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.
What gas does the Spyder take???

Happy trails!
The owners manual states PREMIUM I would recommend that and when you can to get ETHANOL FREE gas, or run a fuel treatment. You can when in a pinch put regular unleaded in but I would steer you away from doing that if at all possible.

:agree: 91 octane is suggested...
...But it'll run on anything that it can get to burn!
For the Record: I use 93 octane in mine. :thumbup:

Octane, schmocktane. :roflblack::roflblack:
Answers will vary all over the board. Most of the manuals suggest higher octanes. Ethanol is another monkey wrench that gets thrown in.
I have always used the highest octane unleaded that I can find. Mostly 91 here in Alaska. Have had to use 87 a few times in remote places. IMO: The performance is a bit more peppier with the 91. Others will disagree. :bowdown::bowdown: We do not have ethanol flavored gas here.
For the 20 cents per gallon extra that I pay for 91 compared to 87--price is not an issue for me.

I asked the lead mechanic at the dealership this question ( I've got a '13 RT Ltd). The answer was that to use more than 87 is a waste of money and not neared. I use my bike a lot so he said don't worry about ethanol treatment unless it is going to get a lot less use.

I use the highest octane because we have ethanol in our gas.

My Two Cents
I am no mechanic, but when I spend 20-30K on a machine, I will always use the recommended octane in the owners manual. For motorcycles, Harleys included, they always recommend 91 or above. I cannot tell you why or how 91 or higher is better, but I am assuming BRP, and other manufacturers, didn't make the number up by chance. I take good care of my motorcycles and if that means spending an extra 3-4 bucks at a fill-up, so be it. Just my two cents.

This. There is no shortage of premium unleaded in my area. I have only used premium in my Spyder.

Due to the relatively high compression ratio of the 991 series engine (12.2:1); it's a good idea to use 91 octane.
The older 990 series engines in the pre-2013 RS could get away with 87 octane as the suggested fuel, because their "Squeeze on the slug", was only 10.8:1
Having said this: The RTs have enough anti-knock technology built into them; that you won't hurt them with 87.
But they'll run better on the good stuff!

I use Cheveron lowest octane. I get better milage than when I use High octane. I do not know the reason for better mpg, maybe they do not sell much high octane and it gets stail.
I just started today adding sea foam, not sure if I will do every othrr tank after the first 3 tanks.
I was told once higher octane burns cooler but not sure about source. I find on forums alot of people talk with authority but are realy nit witts.

The reason for higher mileage with lower octane could very well be how the higher octane fuel that you purchased was built.
Some gasoline makers use Ethanol to raise the octane rating of their conventional fuels.
Ethanol has an octane rating of 109 but not as much energy value as gasoline.
So if you run a tank of ethanol infused high octane against a tank of standard fuel the standard fuel has more energy and therefore the standard fuel might give better mileage.
Still it is better to run higher octane for other reasons.

Unfortunately, this is a multi-faceted question. So, a 1-answer fits all approach is probably missing the mark.
1- The 998 is a high to very high compression engine (depending on model and year). High compression encourages Knock or Pre-Ignition which can destroy an engine in pretty short order. (This is when the fuel ignites BEFORE the piston reaches the top of the stroke, basically trying to run backwards) Very Bad!
2- Lower octane fuels have more energy potential than high octane fuels, (contrary to popular belief encouraged by sometimes misleading advertising). So, you ask, then why do high HP engines require High Octane fuel if there is less energy contained in that fuel? Good question with a fairly simple answer. Higher compression gives you more HP but requires a lower energy fuel to keep it healthy. The increase in HP from the higher compression ratio more than offsets the loss in HP from the lower energy fuel.
So then you ask, why does a lower energy fuel COST MORE!? Another good question. Because the additive which raises Octane is much more expensive than the volume of fuel it replaces. Plus, High Octane fuel sells in much lower volume than low octane fuel. Like anything else. High volume sales usually makes the product less expensive.
So, now that I've bored you to tears. We'll move on. (That is if you've even bothered to get this far!) :roflblack:
3- In cooler weather and low load situations (like running down the highway on flat ground at a steady speed), Knock is not usually an issue. So using low octane fuel will probably give you better fuel mileage without any downside and save you some money at the pump too! Nirvana! You say! Well, not exactly.
4- If you are pulling heavy loads, climbing hills or mountains or doing anything that works the engine fairly hard. Or, if you are running in very warm to hot weather. This, plus the high compression engine are most certainly going to put you into situation #1- Knock or Pre-Ignition mode.
In a normal engine you would be risking your motor. But!
5- The Spyder, being a modern engine, has a computer which monitors and regulates cylinder head (combustion chamber) temperature. This is one reason it is so important to put Thermal Paste (NOT Anti-Seize) on your spark plug threads! If the computer senses temperatures which could cause Knock or Pre-Ignition, the computer takes steps to reduce those temperatures. Kind of like an engine protection Nanny. To do this the computer retards ignition timing. That works GREAT for cooling down the combustion chamber and preventing the dreaded KNOCK! But it also reduces power and MPG. The more the computer has to retard ignition timing, the greater the loss.
So, the hotter, harder and more loaded the conditions, the more you need higher octane fuel.
Will the Spyder run on just about anything? Yes.
Will it have more power and get better fuel mileage on low octane fuel? Under the right conditions, probably.
Will the Spyder have more power and get better fuel mileage with high octane fuel? Absolutely! Under any condition that would otherwise cause knock (which are many).
Will your Spyder ever experience engine destroying Knock or Pre-Ignition with low octane fuel? No. The computer pretty much takes care of this at the expense of power and MPG when necessary.
Should you run 91 or higher octane? In my opinion, yes you should.
Now, about the oil you're using! :roflblack:
