Lead Additive/Octane Booster

[madmaxx]

the octane booster that is sold at auto parts stores is a farce. My boat was pinging so i tried some octane booster and there was zero change. I filled up with 91 octane and zero pinging over the next 5 tanks.

Yep, they usually advertise it bringing the octane up a full point. What they neglect to let you know is there "point" is 0.10, 1/10 of a full point.

Snake oil in it's truest form...

I have never had pingging in my engine, the reason to use the octane booster is to compensate for the gas quality that we sometimes get. I have notice a huge difference between the gas in the summer and that of the winter gas. I feel winter gas works better in my car. That is why before I place the car away for the winter my last fill up coinsides with using wintergas. The lead additive I used to use it in my 67 Volvo to reduce the valve damage and thought would do the same with the Cobra. However, getting the lead additive now is very difficult, not every store carries it.

Lou,

Though I run 110 leaded racing gas in the 69 Cobra, I still use Sta-Bil in it and all of my other cars and lawn equipment for the long periods they will be setting over the Winter. I have used it for years with all of the gas we get here and it works great. No problems when I go to start something after several months of setting. I just pour it in the tank when I get ready to put the stuff away and then run it long enough to get the Sta-Bil in the lines and carbs and have had no problems.

Exactly,what your gaining is nothing,absolutely nothing......

Basque if your worried about needed lead in your engine, get some Avgas or leaded race gas and add a gallon or two to every tank full of gas.....
Around here I can get 100 LL Avgas from a jobber in 55 gal drums for little more than the price of premium 93 octane at the pump.....I've run nothing but 100LL Avgas in my race car since 2005.......
My old iron headed street engine with 10.5 to 1 compression runs just fine on 93 octane pump gas.......

I had a Sunoco station that had racing gas available at a premoum price, however, not available anymore. Aviation gas is hard to come by where I am but thank you for the suggestions. I will try to drive to a small airport north of me and try out buying some AV gas.

Lou-you missed the entire point. You don't need av, racing or any gas beyond about 91 octane. And you need no lead or ANY other kind of additives.
None of it will add power or increase longevity. Don't waste your money - so you can buy those fancy wheels.
Your set-up will run on chicken soup.

I did not really wanted more power, I think I have plenty, I was just concerned about the effect on the valves by not having the lead.
By the way I do want to change my wheels, how did you guess?
I will ask my Jewish daughter in law to make some kosher chicken soup as additive to my Cobra
Cheers

Lou,
The absence of lead as stated earlier will not hurt for a long, long time of usage. I just don't want you to handle it in any form. Even great chicken soup won't cure those effects.
Listen, especially if you're considering parts upgrades, you need to get the basics better.
Like your idle advance should be between 12 and 18 degrees and 36 or so total-not 8 BTDC.
You probably have a very mild cam and not much displacement so you'd need to coordinate several changes if you're after more power. Ask questions if bigger power is what you seek.
If your car drives fine and gets you around, just leave as is. You can easily get more pep by getting the timing right-not by additives, mothballs, meatballs or av/race gas.
