Is that STP stuff or Techron concentrate worth it?? STP is cheap Techron is moderately expensive. What about Valvoline Engine Care that you would add to your oil? Is anything worth it?

 

The best thing I found out was the "LUCAS" Upper Cylinder lubricant with Injector Cleaners and Fuel Conditioners. It absolutely worth the money and it works great. I gain horsepower and it made the engine is a lot quite, I only hear my Injen intake over my engine sound. You could buy it at Auto Zone.

Just tried STP but only ran a quarter tank through. I'll report if I see anything good. I heard that if used often it will help alot but who knows. at $1 a bottle Ill try it every few tanks and see what happens after all it can't hurt.

 

Ive used 104+ octane just for the hell of it, though i didnt have much fuel in the tank. Ill try it one day when i have more fuel in the tank and when i head back to the track. I doubt it does anything...
