found a couple places selling it and wondered if it worked?
says it has the real tetraethyl lead in it and 3 oz will raise octane 8 points.and help save valve seats.

no one has tried this stuff?

i would think it depends on the brand of product and result you want that thay need to know more.the % in the formula has a lot to do with it.i think a gram or so a gallon is what is used.there are other ways to raise octane.

I have used a tetraethyl lead additive acouple of years ago on a poly 318 that I had freshened up and did not put hardened seats in,guides valve job,seats were not sunk,and put about 3 thousand miles on it but hav'nt taken it apart to see if they were showing signs of sinking.3grand in miles is a little short but may see seat widening,with out the lead.

I'm a little surprised it's available for sale. Don't get it on your skin.

I'd guess that 8 points claimed is .8 of a point. That stuff is probably a very, very weak solution. One drop of pure tetraethyl lead on your skin will kill you. Dave

The TEL products that I've seen use a carrier such as kerosene to dilute the concentration.

here is a link to the site of it.

3 oz to 1gal = 8.0 octane increase.
i thought this would be good for my 440 that has higher compression and non hardened valve seats

Question is - how cost effective is it?

From the Kemco Oil web site...
Octane Supreme 130
Octane boost-fuel additive that really works. 2-16 point increase on octane. Turn a 93 Octane fuel into 101 with 8 ounces per gallon. CONTAINS LEAD! Fouls O2 sensors and plugs cats. Off road use only

One qt by the case costs $10.42 and 1 qt treats 4 gals. So1.....10.42 + 4 gals of the average 93 octane (roughly 2.75 x 4 gals - yours may be more per gallon) = $21.41 for 4 gals /4 = 5.10 per gal for 101 octane fuel. Can you buy 101 locally for that?

actually it was 3oz makes an 8.0 point octane increase. so 1 qt would treat 10.66 gallons . making 93 into 101.

Just for thought,,, E85 is 105 or higher, less than 2 bucks a gallon, and without the little bit of gas in it you could drink it.

Now theres a thought how to get the gas out of e85 without

well holy crap.now i am not sure. there is not much info on the actual web site.
if it does take 8oz then you get 1 octane per ounce added to 1 gallon of gas. thats expensive, i wonder where the other site got its info? one has to be wrong.
wonder how much it takes to keep the valve seats lubed up?

are there any other brands that boost octane? this was just one i came across.

I seem to recall there is a concentration limit (4ml/gallon?) of TEL to be able to ship it. I called VP several years ago when I was checking into being a distributor. One of the real high octane fuels had twice the limit of TEL and I asked how they shipped it? Well, there was some hem-hawing and I see now they don't list it on their MSDS for the fuels. I'd just stick with mixing racing fuel in with pump gasoline for my old cars. One gallon of race gas per tank is enough to protect the valve.

As far as separating the gasoline out of E85, I think the addition of water will cause them to separate. I don't think I would drink it even then since you don't know what else is in there. I'd stick with homebrewing for my alcohols needs. You can legally make 100 gallons of beer or wine, a year per person for personal consumption.

You might check this one out. 48 oz. to 20 gals. for 103 octane.
