Hi, can you use 89 octane for the 08 H2 or do you have the use 91 octane ?
Because I remember that the 03 until 07 H2 can use 87 octane gas.
Thanks....

I use regular unleaded, 87, in my H2 unless I am in the states.. then it is premium, 91-93, baby.... that price difference gives our H2 a treat when we are there....

Re: Octane requirement for the 2008 H2
I run premium all the time along with 100% synthic oils, i found its just an alround better fuel for mileage, burning..everything. Most of my friends out here in the oil patch run diesels and just yesterday i noticed that here in Medicine Hat the Premium is cheaper than diesel now. 129/L vs 121/L
