I am conservative in most respects and therefore had also planned to use a separate tank and filter for the wvo to avoid any down time if filter plugged or to enable an easy switch to dino when weather turns cold.

We have done some experimenting with a 20/80 blend in one of the tractors (fed from a temporary, strapped on tank). We ran under medium load for about eight hours and although all appeared to work fairly well, the blend seemed plenty thick to be running through the IP, idle was uneven, and even in 80 degree weather and it didn't start as quickly as on dino.
