[Vwdiesel] Burning Used Crankcase Oil

Wed Jul 11 21:25:03 EDT 2007

Patrick what kind of shitty metal compounds might one find in used engine 
lube. That's my main concern. The odd pint of waste veggy is more preferable 
for my tastes. Spray old lube onto the underneath of the car. Perhaps drop a 
few candles in it too.
Regards
Mark
