Default Octane Supreme (formerly Lead Supreme)

Kemco Oil out of Utah makes this product. Its an octane booster and lead additive. I have used it for a short while (based on a recommendation from the previous owner) in a true 11.0:1 CR 396 motor and have been pleased so far. The motor runs very well, no pinging, no unusual sounds. Am interested in others experience with this product. I like the fact that I can store this chemical on my shelf in convenient quart bottles and just add it to the tank prior to fill up. I used to mix a leaded 110 octane racing fuel with 91 octane pump gas in order to acheive appropriate octane.

Kemco Oil

Thanks.

I'm sold. Just ordered some. I run a blend of 110, 93 and lead additive now. We'll see how this works.

On a slightly different tangent: what has been your experience with a target octane, for example, on a 11:1 CR motor? My understanding is that you are wasting money with overkill, i.e. too much octane or running straight 110 octane racing fuel. Where is the point of diminishing returns? Is the lower end of this (i.e. too little octane) defined by detonation and or poor engine performance? Guess I am looking for a formula or procedure to determine target octane with an eye toward maximizing performance and balancing that with cost effectiveness. Any lessons learned out there?

Thanks!

That's a good point, Sam...99% of the folks out there have no idea what their *actual* CR is...unless you cc everything you're just guessing. I'd say the vast majority of the engines out there are well below where their owners think they are. And while running too much octane isn't as physically detrimental as running too little, it *will* hurt you performance-wise, and make your car temperature sensitive...been there, done that!

If you are building an engine that will run on 93 octane, you need to cc the heads. Otherwise, it really doesn't matter what the compression is. If the engine is detonating (you hear it or check for signs on the plugs), you need to make some tuning/fuel changes. If your engine is in sound shape, and you like the timing and distributor curve the way they are set, you need more octane to resist burning too quickly in an engine that detonates. You may get away with lower octane if you are not driving hard

I have not had real good results with boosters, and still mix racing fuel with 93. The ratio depends on the ambient temperature.
