Also for those seriously interested I can send you a free sample for 4 tank fulls! You will fill the difference on the first one! The gas burns better and cleaner!
A "natural substance" huh? Isn't tar a natural substance, maybe sand? Hmmm... And I'm sure naphthalene is wonderful on my catalytic converter! Just wondering...in 2,000 miles when I need engine and exhaust work done, will you do that for free too?
