Sunoco actually uses tetraethyl lead additive in their gasoline for anti-knock. It is used as an octane booster.

I thought lead was prohibited in gasoline?

It was widely used when I was young . I also thought it was banned for automotive use . Do not know if it was banned for aviation gas ?

It definitely is prohibited in street gas and has been for decades. Where did you see that - a very old pump or something? Race fuel would be my guess.
That makes the most sense. Their 87/89/93, etc. don't have lead but certain stations may elect to sell 110 leaded or some such thing - more common near racetracks or something.

Here in Spain we had leaded fuel until IIRC 01/01/2003 is when it was officially banned.
Cats were only made mandatory in 1993, i had a 1992 Ford Escort 1.6 Ghia, Carb and no Cat.
Although by 1985/86 most cars were already made to be able to run on unleaded.

I have to use a lead replacement additive in my 1975 Ford Capri.

It is still used in aviation gasoline.Testing non lead fuel has been going on for a few years, but not yet certified for use.

OP, give us the Source of this (mis) information?

I say absolutely no for Automotive road use for decades.

MMT was in use for a while as an octane booster, but that was garbage, fouling plugs and lambda sensors.

A gas station near me sells 108 octane race gas for off road use. I would assume that has lead in it. But I might be wrong about that. Big Bucks. Usually 3x the cost of 87 no lead.

Indeed. I smell a troll.

I understand the use of lead for aviation.

There's low lead aviation gasoline. There's also leaded racing fuel.

https://www.sunocoracefuels.com/tech-article/race-fuel-101-lead-leaded-racing-fuels

Lead is still allowed for other applications including off-road recreational vehicles, construction equipment, marine engines, racing, etc. NASCAR switched to unleaded, but they had leaded for a few years after regulations banned it for on-road use.

It was listed in the MSDS regarding their Supreme Fuel 93 octane.

I suppose I will be ditching Sunoco Gasoline. They are also off the Top Tier list.

Sunoco’s “Supreme” is a 112 octane leaded race fuel. Their lowest octane race fuel is a 95 octane unleaded called Optima.

The SDS I found for 93 octane, E10 Sunoco gasoline shows no TEL. https://hometowneenergy.com/wp-content/uploads/2019/05/MSDS-Gasoline-93-Octane-10-Ethanol-2019.pdf

I found this. Not sure exactly what this means outside of California. I'm pretty sure it would violate EPA regs for on-road vehicles.

Yeah, lead was banned for use in motor fuel for good reason - breathing in and touching lead ain't good for biological life forms!

If a guy wants higher performance from an engine such that higher octane is the only way left to get there, it's time to move to diesel or gas turbine that can combust at higher pressures without detonating.

A lot of E85 FlexFuel engines have maximum performance on maximum E85. It will come at a hit to range and (depending on the cost) cost per mile. There's also the chance of there being less ethanol resulting in a lower octane rating and some differences based on the octane rating of the gasoline. E85 is supposed to have an AKI octane rating of maybe 102-105. Not only that, but we go through all these ways to boost the amount of oxygen via more valves and forced induction, but this is introducing oxygen that doesn't have to be compressed.
