Marvel Ultimate Fuel and Motor Treatment in both the engine and gas tank. I used 1/2 a bottle in the engine last oil change and regularly put 2 ounces in with a fill up. It keeps it running smooth and I read it can help keep your catalytic converter clean also. I've also used Redline SI-1 and have switched to this because it is easier to obtain.

Just about any of the above using PEA not called Redline, Royal Purple, or Amsoil. Techron is probably first choice, Gumout and Rislone FSC are about tied, Rislone has a $5 rebate on theirs making it about $2.38...
