Aviation Gas

Post by donaldm » Sat Oct 03, 2020 9:13 pm

is aviation gas 100LL acceptable to use in a Model T fords? 100 meaning obtain and LL meaning low lead. I understand it has a longer life span than todays pump gas. also is it radially available at smaller airports? in advance thanks for your help,

This is the section for help with the site not car questions, ask on the general forum.

Yes, your T will run on 100LL. Your exhaust will smell different and you may have to run more spark advance due to the lower burn rate. Your spark plugs will foul faster and your exhaust system will corrode eventually due to lead deposits. Think back to spark plug and exhaust system life on cars from the 1960s.

Your wallet will certainly be lighter from the expense.

Be aware that it may be illegal to burn aviation fuel in a motor vehicle in your area, since aviation fuel is not subject to road taxes.

Tetraethyl lead was just starting to be investigated as an additive to motor fuels in the 1920s, so Model Ts did not use it when they were new.
