LEADED vs UNLEADED

[CobyRupert]

I have vintage advertisements from the 1920's... still remember my Great, Great Aunt filling her Rambler only with Ethyl... as kids we thought that was a person's name.

Who doesn’t remember pumping Ethyl back in the day...

It is for me because I buy it for my small engines at stations which carry premium with no ethanol; there are more and more of them popping up all of the time. It costs a little bit more, but still cheaper when you consider how many gallons of stale ethanol gas that I've wasted in my burn pan.

I would absolutely buy premium if it actually did NOT have ethanol, but in my case there is no difference in ethanol content by octane/grade.
State statue: "non-ethanol gasoline may not be dispensed from a pump".
Too far for me to drive to Maine for premium.
The only choice I have is 100LL at the airport (pump exception).

Oh for frig sakes , where do these unleaded-leaded and detergent-non detergent questions keep coming from. Oh please give it a break and bury it. Put decent valves and valve seats in it and run it . How do you think gas vehicles go 300,000 miles now with little screaming high output engines . In the old days of leaded fuel a valve job was over due by 75,000 miles on slightly stressed V8.

MR SUPPER member:thumbdown:, not every is like you than can afford to buy new toys. If you think I'm full of crap stop by any small business that repairs small engines and start preaching about the virtues of the stuff called gas at the pumps. They will laugh you out the front door

Depends on your state. I live in Minnesota, one of the largest corn producing states. Therefore ethanol of 10% or greater is required for use in all automobiles or newer. Ethanol free premium is available for off highway and collector cars. It needs octane enhancers other than ethanol and is usually 70 cents higher per gallon than regular with ethanol. Tetraethyl lead has been banned for use in anything but airplanes for a very long time in every state. There are still something like 750,000 piston engine planes flying that the risk is too great according to the FAA痴 October update where they said Shell and Swift have still not developed the perfect lead free.

In Washington state bulk plants can can have pumps that have real gas that the public have access too. I live near Colville and even though a small town we have two bulk plants both of which sell real gas☺

If they sell leaded gas I would like to be able to turn them in because the share of the fine I would get for turning them in would be like winning the lottery. Only sold at airports for older piston engine planes. Ethanol free premium sure, but not leaded.

Blacklion66...states that bulk plants in Washington can sell "real gas".
He did not equate "real gas" to leaded gas.
I would assume that he was describing "real gas" as non-ethanol gas.

Your definition of "real gas" is ??

I think some folks are missing the primary purpose of tetra ethyl lead in gasoline: Its primary purposes is an octane increaser to reduce knock and pig. The secondary effect that is mentioned in these post as an upper valve lube was interesting and secondary. Just like MTBE after it and now ethanol the primary purpose is octane control. Other chemicals work as well like toluene, but its too expensive and the EPA complains if used as a mass market additive.
