Regular or premium, that is the question???

[Zoot]

Just for further reference, I stopped for gas in the cage this weekend... Arizona prices and octanes.

Regular, 87 octane. Midgrade, 89 octane, 30 cents per gallon more than regular. Premium, 91 octane, 20 cents per gallon more than midgrade.

You can run 87 Non Ethanol and 91+ if it has 10% maximum Ethanol.

Using 'new math', I believe "your" difference between Regular and Premium would be .40 or $2.00 per tank. I personally believe running premium in a vehicle 'designed' to run on regular (says so in the manual....) is a waste of money. But as they say, YMMV (so true.) I've run regular in my 'high performance' Yamaha FJR1300 for 91,000 miles and consistently get anywhere from 40 to 50+ mpg. Good enough for me.

I have a pdf copy of the owner's manual from my 2017 RT and this is an exact copy: "Recommended Fuel: Use premium unleaded gasoline with an AKI (RON+MON)/2 octane rating of 91, or an RON octane rating of 95."

Maybe you have a different model but MY manual definitely does not say it's designed to run on regular. Is regular safe to use? Probably. Do I care to find out the hard way if it isn't? No, for a couple of bucks a fillup, I'll use 91 octane. I do not claim to be smarter than the owner's manual and I do not want to prove or disprove that by disobeying something as clear as this.

Interesting read.

Here in Australia
91 Octane is the lowest for mowers and stationary motors and older cars that used leaded fuels
95 Octane is recommended by BRP in Aus models
98 Octane is premium, about 8-10c/Litre dearer than 95, but I use 98 Octane in my 2017 RT Ltd I get about 15% better economy

This thread is in the Ryker section, so I would expect that your manual would be different.

Here is what the 2019 Ryker manual states,
Recommended Fuel
Use regular unleaded gasoline with a minimum AKI (RON+MON)/2 octane rating of 87, or an RON octane rating of 92.
For optimal performance, use 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.
NOTICE Do NOT use fuel from fuel pumps labeled E85

I pamper my Spyder Premium Ethanol Free whenever possible.

Since we are talking about the Ryker, the manual says 87 octane minimum and 91 recommended. Use something in between those numbers.

[Highwayman2013]

It depends on the way they calculate octane where you live. In the manual for the Ryker in the US it's AKI(RON+MON)/2

Or you could use some common sense that always works.

Soooooooooooooooooooooooooooooooooooo NO Diesel then …. correct ….. Mike

[Tslepebull]

My Rally and the lawn mower are the only vehicles in our family fleet that don't use diesel. If CanAm offered a diesel Ryker I would be first in line.

One thing to consider is elevation. You can use lower octane at higher elevations.
