Premium or regular gas?

[Weapon X]

Same cuz there no reason to run above 91 on Phazer motor.

 

[pat the rat]

i only run regular fuel with mine,its got 24000 km or 15000 miles,never had an issue

 

[Yamanimal]

pretty sure the 91 rating is to a European standard which is the equivilent of 87 in North America.

 

[irish_redneck]

Our pumps in NY have 87, 89 , 91 or 93

Don't remember any "91" from living in Ireland.

 

[Yamanimal]

read your manual.

 

[irish_redneck]

from my manual :

Your Yamaha snowmobile engine has been designed to use premium unleaded gasoline with a pump octane (R+M/2) of 91 or higher

 

[Yamanimal]

see how easy that was. when in doubt check the owners manual

 

[irish_redneck]

no-one needed to check the manual, as stated earlier a big stixker next to the gas tank says "91"

 

[blueironranger]

It's a 91 octane "recommended" engine unlike some other engines that are 91 "required". Yamaha says 87 can be used if 91 isn't avalible but there may or may not be a loss of performance with 87. About 70% of my miles are on 87 E10, but I will use 91 "pure" gas if its under 30 cents difference in price as I do notice 1-2mpg better mileage and a touch more squirt with 91 Dino gas

I've always run 89........... it's in the middle and had no problems beating the Irish Redneck on the 91 octane, carrying more weight than him

Were you all out in our little race last night? LOL

 

[evilminivan]

same with me, local station on the trail has no ethanol in there premium

 

[irish_redneck]

Nah, I also started after you cos I wasn't sure of your intent

 

[irish_redneck]

I'd also imagine pushing the extra 15" track weight would reduce my top end?
