I was wondering how many of you guys use it, and is it really worth it?

 

I use Startron Starbrite additive that helps with the ethanol issues, I don't bother with HD's additive

 

Imho,if you are going to use any type of fuel treatment use the lucas fuel treatment.

 

Do you guys think that its necesary to use, Or can I get by with just running the 93octane gas, All I have is Rinehart, PC, and a upgaraded air filter?

 

I use it to keep the engine clean its more of a lubricant than anything helps keep the top side of the piston and valves lubricated. Also it helps with low octane just incase that 93 is really 89.6 cause it sat there so long or a pumper made a mistake.
