My HO only has 8 plugs. I thout they called for 93 Octain.
I was going to buy a new Dakota w/v6 but after having one w/v8 and no mpg loss, I think it was a no brainer. Now if I could just keep my foot out of it. HAHA that will never happen....
Holy cow, what is the deal with all the old threads comming back? LOL, manifactures recommend higher octane levels for certain engines. Dodge says to get the most out of your 4.7L HO, use 91 octane.
