Chevron Techron Concentrate Fuel System Cleaner (20 oz.) $6.50 (reg $13) free pick up ADVANCE AUTO PARTS

Quote from xlr8tion : It's a scam. Show me any reputable report of where it makes a diff. Most gasoline has detergent additives in it with all engines pretty much fuel injected. It's like the 93 octane scam...... I have a LS2 6.0 Corvette motor in my 2006 GTO that asks for Premium. I run 87 or 89 and the black box adjusts the timing accordingly. No knocking or detonation problems..... Oh...get your oil changed every 3000 miles too...NOT

Okay...first let me say that I agree with you on detergents in our gas. Most brands of gasoline (yes, I -KNOW- there is a difference in formulas from one brand to the next, hence one brand can be "better" than another) does incorporate detergents into their mix at the pump. That said, the concentration level is much less and the quality/effectiveness of said detergents varies. (Out of all concentrated cleaners on the market, Techron is the only one I buy.)

Now, as to your LS2 Vette engine...so your getting less output (HP) from your engine whenever you use regular gas, as your engine's fuel management computer retards the timing of the engine to avoid it being harmed by premature detonation. What part of that "equation" do you not understand?

What I understand from what you said...

You went with a high performance sports car to get all cheapo on feeding it a "proper diet". Why bother getting the LS2 engine then? Why bother with a muscle car, period!?!

Why do you naysayers always come in to these threads to spout your garbage about how ALL (eg; generalizing) those fuel additives do not work, when you are not any more qualified to speak on the particular product at-hand than Joe Schmo?

I have a 1999 Yamaha YZF-R6 that has a carburetor. Remember those? No fancy fuel management computer anywhere in there to retard the timing to prevent a damn thing. My engine was worked over by some boys out of Ohio that raised its compression to somewhere around 11.5:1 (over 10.0 stock). Were I to try something as stupid as what you've done with your LS2 engine, I'd probably end up breaking my engine within a 100 miles of gassing up. No joke! Not to mention that the bike would run like chit and sound as if its playing back a prerecorded shootout at over 110dB (out my Micron carbon exhaust w/no baffling/spark arrestor), backfiring whenever I throttled it up too quickly.

You sir, should take your GTO and trade it in for a Honda or Toyota. Nah, go with an Acura or Lexus, as that probably would fit the bill for you a bit better. I believe most of their engines pretty much run on regular gas and have compression levels low enough (8.0-9.0) that the grade of your fuel should not make a lick of difference. Then you can go all cheapo on your ride, not worry about its engine performance, and trade it in before you would ever need to even think about fuel additives.
