Dinol/ Dinitrol for cars is not sold in Canada - except AV-30 in spray cans 
- and then you have to buy a case of 12 -  Oh yes and they do have 19 litre 
cans !!!   What is 3125 specified for?  I know they use Dinol in the UK for 
cars but when I spoke to the US chap he said Americans were not interested 
in quality just price so they only sell to the aircraft industry - and 
AV-30 was as close he could advise to do cars
