Gasoline Octane for 2014/2015 RT Limited?

[odyssey009]

Gentlemen:​
I'm in a quandary. The owners manual suggests using 91+ octane gasoline and the service manager suggests using 87 octane.
Please tell me what you are using for the 1330, three cylinder Rotax engines.
Thank you,
Michael :shocked:

Here's the thing..!!

In the US you can use 87 on up. For the difference of a buck per tank it seems you would go for the best Considering these are not cheap machines. The name brand higher octane fuels also have additives which help protect many engine parts. If you run lower octane and add additives your back up to the same price and effects. My suggestion...go for the best you can get in your area...:thumbup:

Look on the label under your seat. Its very clear. 91 octane minimum. Suggest you show your dealer.

The engine has a static compression ratio of over 12:1. Yes it will protect itself if it hears detonation from lower quality gas but that should not be your normal operating mode.

I use nothing but premium and have had no problem finding it anywhere, non-ethanol is another matter but I have not seen any change in running non-ethanol vs premium with ethanol except for price, one station was $1.40 a gallon higher for non-ethanol vs standard premium.

I view the manual's instructions as protection of my investment. You're not driving a Yugo!

 

[Bob Denman]

Use 91 or better...

You CAN run pretty near anything that'll burn; the engine has enough techno-wizardry in it, to keep from shaking itself to death.

But you might as well run what the engineers say to use... :thumbup:

When in doubt, the manual wins. This particular subject in the manual is correct. :thumbup:

Service managers, sometimes they don't get it. :yikes: I am guessing he/she may not drive a Spyder.

Most will state that the Spyder seems to like higher octane better than lower. I have used premium in all five of the Spyder's I have owned. I do notice a difference if I am forced to use 87 octane.

Hear in GA, we have 87,89,93 octane and put 93 in my :f_spider:. Since the Owner's Manuel calls for 91 or higher that is what i go with. I figured BRP know more about what's best for it than i do. opcorn:

93 octanw

My 2014 RTL sure seems to perform better with 93.

Hi Odyssey009!
I took your question to our service manager here at Brewer Cycles. He very seriously said "you can't recommend against the owner's manual". So, he'd def go by whatever your manual says is best. I think someone recommended that you take your manual in and show the service manager - probably a good idea. It sounds like you got good advice from your Spyderlover friends!!! :-D

I use 91 in my Spyder.
I have been in the position on a road trip where only 87 has been available at a pit stop and never had any problems but premium is what my first choice always is.

 

[Highwayman2013]

I use 91 unless that isn't available.

 

[Bob Denman]

Has this horse been sufficiently tenderized yet?? :bdh::bdh::bdh:

:roflblack:

 

[Buggy]

I have used a few tanks of 94 and the Spyder is running better than ever....maybe it is just breaking in more and not the 94 but I will continue to use it when available.

The pumps in my area sell 87, 90 & 93 octane. So, I experimented and found:
1) using mid-grade in 90 degree temps, I would occasionally experience knocking when slowly accelerating from a stop. The knock would dissipate once the engine was turning >1200 rpm.
2) using high-grade 93, there was no knocking or pinging in the same ambient temps.

In the rare case I happen upon a station that provides 91 octane I may try it, but until then, I will stick with the 93. Especially in the warmer months.
