Talk about clean looking fuel. Like clear with a tint of blue in it. And the smell you'd never forget. Basicly I decided to try the 100 low lead gas because I heard it lubricates your valves and such in ur engine, unlike unleaded fuels that will not. I ran my car almost empty and then added 5 gallons at a price of 4.19 a gallon. Ya know I don't wanna be full of it, but I honesty think I felt a seat of pants difference. But i'm un-sure. Oh and for anyone else that want to try this, it will mess your car up if you have catalitic converts still.
