[AJD] Antique-johndeere Digest, Vol 82, Issue 4

Tue Jan 10 13:56:56 PST 2012

Not only does the Aviation gas contain some lead, but it is also ethanol-free!! That is a real bonus today, particularly using it in small engines where the ethanol tends to rot the diaphrams and seals. I use it in all of my mowers and chainsaws, etc. Don't need Stabil with it either.
