Gone Posted September 15, 2011 Report Posted September 15, 2011 OK, this is just me reporting heresay - but here goes. I appears that this new certification (by whomever) against ASTM D910, is formal confirmation that the avgas we have all been using for some time actually has less lead in it than the previous specification. ASTM D910 specifies somewhat (significantly??) less TEL in it than the previous one and it turns out that our avgas has contained the lower amount of TEL in it for sometime now. In other words ASTM specifies the lower amount of TEL, which our current avgas meets anyway, so that (at no extra cost to anyone) our current avgas turns out to be much more environmentally friendly than the EPA thought - so they will not fight so hard to take it out of service. Part of the rationale for this move was that the upper limit of the previous specification was being used as the number to calculate the overall environmental damage caused by our use of avgas. Now that calculation has a new lower number to use. Again, this is just heresay. Quote
