I can get 104 unleaded or 110 leaded.... which one should I get and why? I dont run a cat in the exhaust....... so I should be okay with the 110 right?

Be careful leaded fuel may kill your O2 sensors.

Right, use the 104 if you have a wideband or stock O2. Otherwise, might as well go to C16...

Avoid leaded fuel, it kills O2 sensors very quickly.

very quickly.. SO go E-85

Get a drum of 104 unleaded, it will be cheaper, most will deliver to you as well. Get a small barrel/hand pump and your done. The track car has been on 104 from the beginning and when we tore the motor down, the head was almost like new - very pleased with it and no WBO2 problems.

you can use leaded fuel, but its not recomended, as it can kill the o2 sensor in 50 hours or it can go 500 hours before it kills it.

Who makes the 104 unleaded? All I can find local is the Sunoco 100 (GT260 I think).

Sunoco makes GT104. They sell it in 5 gallon cans too.
