Hey guys, regarding the use of lead in fuels, didn't the older engines (certainly in the Model T) actually have NO lead? The lead was, I believe, added later when the engines became more powerful and the lubrication was needed. I don't know if the Model A engines used leaded or unleaded fuel.Jeff in warm North TX in NovemberSay goodbye to busy signals and slow downloads with a high-speed Internet connection!

Tetraethyl lead was never added to gas for lubrication. It is an anti-knockcompound to increase the octane rating. The OWT was added by a publicrelations man. I was told this by one of the engineers that worked at theEthyl Corp during its development. Their biggest problem was killing theoperators of the facility. Many died as it is very toxic.If it lubricated, then exhaust valves would not stick.Cy Galley, TC - Chair, Emergency Aircraft Repair, OshkoshEditor, EAA Safety Programscgalley(at)qcbc.org or experimenter(at)eaa.orgAlways looking for articles for the Experimenter----- Original Message -----

Do the cheerleaders still rev up their chainsaws on every touchdown?Sorry for the off topic.Rick HollandYou are correct. There was no lead in the early fuels.I have run my Model A car and an 1911, 1 cylinder car on unleaded fuels for years with no problems.Lead was not needed until the higher compression engines came along.Roger GreenLibby, Montana________________________________________________________________________________

The only car that I ever owned that really needed Ethyl gas was my 1957Pontiac Starchief Convertible with 10.5 to 1 C.R. Since I was poor at thetime, I retarded the timing just a bit and ran regular. After I got married,I didn't need to put my foot in it as often. It would still run the redspiral speedo around so it would start over at above 120 mph. But at thatspeed the tires would begin to smell and I would have to slow down.----- Original Message -----
