Lead content of fuel per gallon 100LL 2 grams 80/87 1/2 gram regular mogas 1/10 gram unleaded mogas .001 gram It says When you overhaul you engine use avgas for the first 15 hours to insure adequate lead during the break in period. Radial engines should use leaded fuel at all times. A mixture of 25% 100LL and 75% unleaded auto fuel would yield a lead content equivalent to 80/87 octane avgas. That is from peterson aviation inc.

Too bad they don't sell 80/87 anymore. -Joe >I am told the lead content in 100LL is 4 times the auto gas when lead was a >component of Auto gas. --------------------------------- Start your day with Yahoo! - make it your home page
