Some have used less octane in their SVTs and said they noticed no difference . I won't use anything less than 91 in my SVT , though .



i only use 87 in my svt. it says use 91 only on the fuel gage but in the svt owner's manual it says that the engine has a built in "knock sensor" and you may use 87. it says 91 is simply recommended. i emptied my tank and filled it with 91 when i went to the track. per the butt dyno, no difference. its about 20-25 cents more per gallon, ie $255 a gallon out here.
