Pretty good article on octane ratings.

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.

Good Article. I normally run 87 in my Spyder. Runs great.

Just me. I use the highest I can get. Here, mostly 90. My $30K machine deserves the very best. :yes::yes:

OCTANE ?????
:agree::agree::agree: .........To save all of you time ..... just read page #7 of the article...... All my V-twins and now my 1330 have run quite fine on 87 .............. Mike :thumbup:

The article says that for engines that do not require the high octane, its a waste to do so.
The Spyders DO REQUIRE 91 or better to run correctly. Lower octane, less than required by BRP does reduce engine power and can cause long term undesirable effects.
The article is not telling you to ignore the manufactures requirements, it just says not to bother going beyond them for most engines.
All Spyders since at least 2013 have REQUIRED 91 octane gas. Its right on the emissions label on your bike.
Also, while BRP has never been known to do so, use of fluids, including gas, that do not meet BRP specs is grounds for denial of warranty coverage. Other manufactures have done so and with BRP's penchant for cost savings, its not beyond them to do so in the future.
Use what your bike requires.

You can run lower octane gas in an engine that requires higher octane. But most modern engines have knock sensors that will retard the timing of the motor until it stops knocking. When it retards the timing it reduces horsepower and gas mileage because it's not running at optimum level.

Jackie Gleason used to say: "And Awaaaaaaaaaaaaaayyyyyyyyy We Go." :roflblack::roflblack::roflblack:
We have not had an octane thread for awhile. I will stick with what I said in my earlier post. The few pennies don't matter at the moment. My reasons have been printed many times in previous threads. There is no right or wrong. IMHO of course. :bowdown: I will just sit back an enjoy from here. Good to see some action on the site again. :yes::yes:

:agree: Here we go... :banghead:
These engines are equipped with some pretty good anti-knock "Black Magic"...
But if you want them to run right: use what the book says that they need. nojoke
Which is:
Series 990 engines: 87
Series 991 engines: 91
The triples also take 91
But since this always starts a pretty good fight: just run whatever the Hell you want, and be happy!

A loud discussion of octane, is always a good way to start the new year! nojokeFolks can strap on their self-righteousness, and prepare for the oil, tire, helmet, speed limit, and safety gear discussions that follow. :thumbup:

ok i'll put in my two cents worth
usually run 91 octane but have had to purchase gas in some rural areas that only have one pump and was obliged to purchase 87 I couldn't detect any difference in the performance of the roadster I don't believe it makes a big difference.

Bring them on. We need more posters Scotty. :roflblack::roflblack::roflblack::roflblack:
On most gasoline powered engines, because you never really completely empty the tank plus a few other 'control' issues & effects, it generally takes more than just one or two 'tanksfull' of gas before the effects of running different octane fuel become measurably obvious to the lay-person. :banghead:
So running the odd one or two tanks of a different octane rated gas every now & then shouldn't make any difference to your daily ryding, and if you really want to see if there is a measurable difference to your Spyder, you should run at least a few tanks full of the different octane rated gas thru your motor before you start looking/measuring to see if there are any real differences! Which means that for most people, their 'seat of the pants' dyno is extremely unlikely to uncover any REAL differences after just topping up the tank with a different octane rated gas once or twice on a trip somewhere!! :thumbup:

Ok!
Oil, Rotella T6 in the triples
Tires, Yokohama
Helmet, of course
Speed Limit is a suggestion
All the gear, all the time.
If anyone does not agree with the above, your just wrong. Give up and get on board.

The blue bykes must cause an attitude of tyranny, but since I do NOT yet own a 1330, hey I will just agree with Mr. Attitude here!
