tetra-ethyl-lead octane boost

[Nero]

had a brief look at this at Hi-Flow. Gurantees a 5 point boost on optimax, but not for ULP cars. Cost $30 for approx 5ooml and 150ml required in 50lt for that boost.
Anyone have experience?

[slo360]

most OBs claim a lift in "points", but to this day im still confused by this. Ive read tests where these products show little or no change, and when they tried to verify actual octane increase the results were dissapointing. For me, "5 points" would be 95 octane should equal 100 octane with additive, yet in testing it usualy means 95.5 to 96, so i can only conclude that by "points" they meant "decimal points" which is hardly worth the effort, considering a change to better fuel (ie PULP over ULP, or adding acetone to PULP) will cost the same or less and gives proven results. One question though, was the product in question based on tetra-ethyl lead? if so it will kill you oxy sensor pretty quick as well.

[Nero]

Yes, it is lead based as in the top post. A cat/oxy sensor is not a concern as it is for a comp car

[jkaufman]

Yeah by 'points' its refering to a tenth of the number. So 5 points with optimax will boost it from 98 octane to 98.5 octane.

is it banned under cams regs?

analine (sp) is apparently better for the octane increase you get out of it, vs the volume of it you use. (this is from some US porsche nut, so could be completely wrong, haven't tried it in my personal experience)

[Stix Zadinia]

and wasn't TEL the original lead additive from Dupont in the 1920s? and incrediably toxic?

[Wobbler]

Here is a large thread from skylines aus about mixing toulene with normal fuel, might be of interest to some people.

911CS,
Yep sure was. Nasty stuff indeed but loved by petrol companies because , you guessed it , it is so cheap.
When TEL was experimented with there was a great range of alternatives considered but TEL won the day solely on cost.

The toxicity issue was the main factor leading to having the stuff banned from petrol in the first place.

Cheers , Pete.

OCTANE SUPREME 130 (formally Lead Supreme 130)

What is Octane Supreme-130
Octane Supreme-130 is a genuine TETRAETHYL LEAD (TEL) gasoline treatment. Since 1921, TEL has been the original additive that (1) Boosts octane numbers, (2) Eliminates engine knock, and (3) Protects valves and valve guides. Only with TEL can you expect the highest performance in these three crucial areas.

WHY IS OCTANE SUPREME-130 DIFFERENT FROM ALL THE OTHER ADDITIVES ON THE MARKET TODAY?

Octane Supreme-130 contains a high level of genuine tetraethyl lead. Other manufacturer's additives contain lead substitutes, such as ammonium phosphates, amine phosphates, manganese compounds, sodium, sulfur formulas, and others.

There are products that blend a trace of lead with other chemical substitutes so they can advertise a lead product. Octane Supreme-130 is the only product with 100% TEL activate (NO SUBSTITUTES) for maximum performance.

{GTSBoy -- ALL THIS IS OK SO FAR}

IS OCTANE SUPREME-130 SAFE FOR THE ENVIRONMENT?
By adding Octane Boost-130 to your fuel, your engine will perform better by increasing horsepower and burning the fuel more efficiently. {OK} Practically all the lead content is burned and deposited on the valves and valve seats, leaving the environment virtually lead free. {WHAT?!!??!!?}The sun quickly decomposes any remaining trace of lead. {WHAT WHAT WHAT WTF?!?!?!?!?}

HIGHLIGHTS OF OCTANE SUPREME-130
1. The only product with 100% Tetraethyl Lead and other octane enhancing components (No substitute chemicals are added).

2. Boosts octane from 2-16 points when added to fuel. Perfect for HIGH COMPRESSION ENGINES. Eliminates engine knocking.

3. Protects valves and valve guides.

{THIS BIT WAS OK TOO.......BUT.......}

4. EPA registered. {WHAT!!!!!????}

5. Environmentally safe. {YOU TOLD US THAT BEFORE BOYS......WE"RE STILL LAUGHING FROM THE LAST TIME}

6. A superior gasoline treatment.

Why is Octane Supreme-130 different from all the other additives on the market today?
• No High Priced Race Car Sponsorship.
• No Big Advertising Campaign
• No Expensive Spokesperson
• Just Straight Forward Lead Octane Boost

Benzene is fierce stuff from a toxicological point of view. It is both chemically toxic and carcinogenic at lowish exposures, and I think it is also linked with sterility in men (IIRC).

Toluene is a bit toxic chemically, is suspected of having some carcinogenic effect, but there is no real proof. What a difference one little methyl group can make to a chemical hey? It is a blody good solvent and an excellent fuel to boot. I think it is a nice chemical. Of course, I don't bathe in it........

cheers

Olde world speedway racers talk of buying benzeze in drums and adding it to their race fuel...mind you there are not that many of them left any more!
Toluene seems to have the usual carcinogenic risk associated with most petrochemical elements in fuel...one would assume that added exposure and levels in fuel would add to the risk.
I agree with your points re promotional info above. It has been cleared by RTA for use in australia according to the importers. Assuming that the level added does not raise the lead content to more than std levels I cannot see the harm. The users of this addative would not be frequent users of their cars and the historic guys will be happy to add it to optimax etc for their old race cars to meet the old octane rating of '5 star'

Putting a bit of te lead in your fuel is no big deal- Avgas had loads of lead before- and think about everybody's cars burning millions of litres of leaded fuel only 15 years ago-

Put some in if it works and don't drink it or run the engine in your kids' play room!
