Question is in the title. I had used this stuff years ago but can not recall where I got it. Appreciate your help.

Why do you think you need it? The myth of needing to replace your valve seats in heads was dispelled long ago. Just add the gas of your choice without worry.

It was tetraethyl lead, suspended in kersone, so that i you spilled it on yourself, you weren't exposed to lead. As if kerosene was good for you...

I used to buy it in the way back too. Stopped making it in the 90s. Was in a silver can. I dunno...might have bumped up the octane a touch. I used it every four or five tanks and then when it wasn't available I stopped (of course) but I never missed it.

Yes, not cheap or legal for highway but does seem to make some difference. An additional octane or two might or might not make a difference to knock resistance but if you think you need lead for an engine that lugs a load then there’s this.

Another option is VP Racing Octanium (not the unleaded version).
The leaded version contains TEL, under 0.3% according to the data sheet, and one quart in 10 gallons is good for 8 extra numbers.

Compared to the Octane extreme listed above, this seems to be a very similar dose rate for extra numbers gained. Yet the website claims "59.4g TEL per gallon", which is 0.1%, yet a data sheet for it found elsewhere state 1.2%. Maybe I screwed up my maths. But struggling to find up to date sheets from the oem. Atleast VP Racing is up to date and clear.

I use the unleaded VP Racing booster in my litle turbo daily after an over zealous tuner have me a touch too much timing advance on my map, causing pinging. While I wait for an exchanged ecu I'm running a lose dose that's safe for these modern sensors, but it only gives me an extra 3 points, although that is enough for smoother running. But that's my only experience with it, and not with the leaded version, although it is recommended an a diferent chap I know who is a tuner in his spare time and a pilot as his day job:

Thanks so much. It was driving me crazy because I could not remember the vendor that had it. I just remember it being in a yellow can. Did many searches on internet and it did not bring it up. I thought maybe they shut him down like they did all the lacquer paint stores.

Years back I used to buy TEL by the case from Jack Podell. He is a fuel inj restoration specialist in Indiana . He adverised it in Vette Views and or Driveline. It was the real deal. Great for really raising octane for high compression engines. I am not sure he sells it anymore.

Avoid it like poison because it is.

Go to a small airport and buy avgas.
