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'm using 87 octane on my h2 since 3 years without any problems.

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....

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

I USE PROPANE , BABY IN MY 2008 H2... /.63.9/L

I use 87 in my 2007 H2 no issues.
