I'll wait until you post some references or facts.

Now can you please explain how 16 ounces of an octane booster with an octane rating of 99-103 would raise my octane any noticeable amount?!

By my math:

16oz (0.125 gals) of 103 octane: 12.875
19.175 gals of 91 octane: 1744.925

1757.8 / 19.3 = 91.07 octane.

An increase of 0.07 points per tank.

What am I doing wrong here? That can't be right. How do those things work?

Scroll up.

Lucas actually beat out torco for bang for the buck when I tested it:

Well going some very well known people/engine builders that i know and have met in racing, Torco delievered a solid 103 octane over 91 octane with a 32oz bottle! So if your running the TurboTuner i guess you can have a race tune 103 octane setup if you like!

I've heard similar...but around here, the Torco is not commonly available. The Lucas, on the other hand, is in every auto parts store in the area.

Here is the graphs for Torco:



Those are (ron+mon)/2. If you assume RON then you get something like 103-105 with Torco.

So wouldn't that mean the methanol could have the same non-linear effect on the final AKI of the fuel mix that the octane boosters do? I think that Lucas one seems good for the money.

It could in theory, ie if you didn't know the chain structure. Its relation is not perfectly linear, but it is pretty close. Couple that with concerns of piston wipe and water and itt does not make a very good octane booster in high concentrations. Its a great fuel dryer though as you pointed out. If you want to run methanol just dump a few bottles of gas dryer in the tank.

.. thats why a lot of people are going to oils like Redline and Motul which are very high in zinc.

I think I'm going to switch to Lubro Moly instead. MOS2 has similar anti-wear properties, reduces blow-by by coating the pistons and is completely safe for catalytic converters.

Q. What is "Moly"? A. “ Moly” is the short name for the substance known as ( it’s scientific name) Molybdenum disulfide. “Moly” (Molybdenum disulfide also called out as MoS2) is a naturally occurring mineral, formed and mined with other ores in various parts of the world. It is highly refined and processed into sub-micron particle size at which time it can be used as a “solid lubricant.” It possesses the properties of being able to withstand extremely high load capacities (400,000 psi). It is chemically stable, has a very low coefficient of friction (0.05 to 0.09 in powder form) and has thermo-stability over 2,000°F. All of these properties are essential to reduce metal to metal contact and thereby reduce friction, heat, and wear.

I don't see any reason to keep using zinc.

Its cheaper, softer, and can be burned out. Why use moly?

[Naughty33W]

i use a bottle of lucas motorsports 3X octane booster per 1/2 tank (9-10 gallons usually)

no doubt my "butt dyno" can feel the extra pick up

i actually chose to try it after reading Chucks article on octane boosters - so far i'm very pleased

With TN tax two bottles of MoS2 was under US$10 at NAPA (part number AIC LM2009). And based on a "Bob the Oil Guy" analysis one can seems like plenty for the 7 quarts in my S80. Also BTW, I found out Redline added moly to their blend and the Mobile 1 0W products have a little in them too, so you might be using it and not even know it. In any case, I can now say from experience that my cold starts are completely different. I make a lot of short trips and this product is definitely the shiznit IMHO. Probably not worth the cost of using Lubro Moly oil though, which is kind of expensive.

Ended up using the other can of moly in my Honda. Has a noisy/sticky lifter than always made a ticking sound when cold. Noise has completely disappeared now. I went and bought four more cans of the stuff at NAPA just to have around. Prices online are double. Don't know why it's so cheap there. They can never find the item though, even after scanning bar code from an empty can. You have to give them the NAPA part number LM2009. Lubro Moly's part number is just plain #2009 but they can't find it with that for some reason.

Anywho, as a side note, I was reading the label on my Centrum Silver vitamins and lo-and-behold it says molybdenum 45 mcg. So apparently it's not just safe for catalytic converters but you can eat it too. LOL

I'm sold on the stuff...

Lucas oil powersteering fluid/additive. cured my noisy steering within the first drive.

+1 I did this last week. Helped great in the cold when starting my car. PS pump would make noise and vibrate motor from what I would assume is a worn bearing . Added 1/8th the bottle and fixed it within seconds.
