I ran Lucas Octane Booster this last time I filled up (http://www.autobarn.net/luocbo15oz.html
), it cost me 8 bucks for this bottle at NAPA. Here's a coule of Q/As:
Q: Did you feel the difference?
A: YES! I really noticed the difference between 2500-4000RPMS. It just seemed t pick up and go better then normal.
Q: Would it be worth it to run this every time I fill up?
A: No. I would only run this maybe once every four fillups and before you plan on going out and racing if you race. It's good the engine to have higher octane in there every once in a while anyways. Cleans things up.
Q: I have engine knock and other weird sounds, should I try this?
A: Yes, you absolutley should! I wasn't having any problems before I ran this, but it's meant to clean up those problems.
I was 100% impressed with this stuff. What I did was, I ran my tank all the way down, put a 1/4 back in, about 4.5 gallons, put the booster in and then fille the rest of the way up to get it mixed good. I put in 92 Octane also because I have a JC Chip. I would recommend this for sure for those of you who are racer (not ricers) at heart :P It does get expensive though, so I'm only going to put in once every 4 fillups or when I plan on going out and racing. PM me if you have any more questions.
