110 octane?

MS109 has an octane rating of 105 and is unleaded. Sunoco offers a 104 octane unleaded fuel. You won't get these from any pumps at a gas station though.

Sunoco makes it. Lead is just an additive used to lubricate the valve guides in racing applications. Most forms of racing now require the use of unleaded fuel.
The big thing with the lead in new motors isnt so much "frying"the O2 sensors as it is gumming up the fuel injectors. Thats why you cant use it in anything fuel injected even if you remove your cats and sensors.

um, yes it will. In my v6 I ran a full tank of 87 octane at constant speed on the interstate with no jack rabbit starts and only went 290 miles. I then filled up with 89 octane the next week and did the same route at the same speed with the same starts and went 325 miles using the same amount of fuel. then I tried the 93 and went 330 miles on the tank. This was all without a tune. Right now I run 89 in the GT, which is stock, and I am avg 370 miles per tank, or 24.3 mpg(per the msg center). Im yet to run a tank of 87 through the GT though.
