i was just wondering today what octane gas you guys with yfz's are running. they have a higher compression engine, so im guessing 87 isnt gonna cut it. :sucks <--beat you all to it, but curiosity got the best of me

by the seat it had a sticker that said premium (93 octane) but thats what i always run anyways if i dont mix it 1/2 and 1/2 with VP 112

I usually run 93. However up in Silver Lake I was mixing 110 and 93 so I would say about 100 octane for like 3 or 4 tanks. The higher octane gas smells good though! :lol

it says to run premium....... but it says that it needs to be 91 octane at the lowest

I run premium (91 octane here in Utah).

In the the owner's manual I read a section where it says to AVOID LEADED fuels! It talks about lead having a negative impact on various engine components!

I was very surprised to read it.

i know that. you shouldnt run leaded fuels in quads, period.

I believe Vp and unaccal and K&S are leaded fuels at least the barrel of unacal 76 110 I had said leaded

Almost every high octane gas has lead in it. My new piston will be a 13.5:1 so I will have to run straight VP Ultimate 4. This stuff is $8 a gallon, but it is the best money can buy.

I have been running Mobil 8000 which is 98 octane. Thats all I have ran, and that is all I will ever run. Works great!

I know a lot of the octane boosters contain lead in them also.
