• 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.

Gas Octane

Once upon a time, a wicked scientist created an indestructable thread, that was endless, and could never be destroyed...

Wait...so you're saying that gasoline is available in different "o c t a n e s ?"

Gee, I wonder if switching to a premium gas will boost performance. Or maybe mileage. We should do some long term tests under controlled conditions. And maybe we should do a dyno test. Unless we can't.

(OK, n o w is this the longest thread we've posted to? It sure seems reminiscent in length to the old "How many PE Spyders does it take to screw in a lightbulb?" threads...)

Man, HDX, you weren't kidding when you told me about the "Octane Wars!" :joke:

You could probably visit any website on the internet and there's at least 1 octane thread and a thread about an airplane on a conveyor belt. They all read exactly the same and have similar outcomes. If you find yourself in an eviroment where one or more of the engines you run needs the higher octane to operate correctly...use it, if it's running fine, don't waste your money. My cars and motorcycles didn't need it in seattle, but the Focus and TL1000R had to have it in the El Paso desert. The Caliber and Odessy don't need it, but the SV1000S did and so does the Spyder. I've never needed it in a V-8 or V-6.

Well why didn't you just tell us when the discussion started; you coulda saved us all a bunch of time!

Of course, even tho you knew the outcome, I see you read to the end.;)

Just goes to show, what else would we be doing if we weren't here reading undead threads?

Gas octane and oil threads will never die - - have continued to live on motorcycle and car forums so why not Spyder forums.

Dummy me uses lowest octane that is recommended by manufacturer and oil that meets manufacturers specs. My approach is not recommended for anyone because it would mean the end of the best and longest threads of all time.:):)
 
What I really want to know is...if you have an airplane on a conveyor belt that can instantly match the rotational tire speed of the airplane...can the airplane take off?

Yes, unless the wheels break from the tires rotating so fast. :D Then airplane go boom boom.
 
When I took delivery of my Spyder on Saturday, the dealer recommended burning only Premium. That's all I need to hear. :thumbup:

Beware the dealer that tells you something different than the BRP manual. Not necessarily a bad thing, but then again... I would question this guy unmercifully.

Hey, Scotty, what octane fuel do you use in that tricycle in your avatar?!

Strictly regular (with fuel stabilizer) in this crate motor. The old hotrod Briggs required premium, though. Milled head and thin head gasket on that one. No knock sensor here. :D

I believe that the minimum octane is going to perform the best because thats what the ecm was calibrated for. 93 octane takes for energy to burn, in other words, it would need the timing advanced to take advantage of the better fuel and show gains.
 
Ok, I'm like adding my 2 cents worth for to debate, but unless I missed a post in there ( come on folks 4 pages, alright already) anyhow.....The science proves the need or lack of it and supporting technical info shows that in a controlled enviorment, an engine that does not require a slower burn does not benefit from a slower burning fuel. That argument aside for a minute, lets also remember that all states are different in the winter/summer blends, and the amount ( screw the label on the pump ) anyway the amount of ethanol or other gas oxygenating crap they put in there, also artificially rasies the chemical cetane ( correct wording?) and also affects the Rom number. We have a mid grade fual in the Illinois, that when mixed at certain stations is cheaper due to the corm alchohol and additives, that allows the octane rating to be higher, and the btu level to be lower. Guess what, lower BTU, less power. In you grandads car who cares, in my SPyder at a critical stoplight drag against a felow hotrod, or God for Bid, on a cold day of riding, (yeah we ride in 15 degree weather) it then makes a bif freekin difference. I personally, avoid as much grain alcohol or ethanol as possible. I will say this, I ride from full to about a quarter indicated (2 bars) put in 4.? gals, have a smile on my face and could care less how much fuel mileage I get - Its the fun factor for me! Otherwise 37-38 is not bad and I am having the time of my life. If I wanted fuel miege, I would have bought a freekin scooter - Ok I feel better, you all may continue the great fuel debate - I always enjoy the banter :)
