i just started running straight wvo... and I am thinking about going to the junk yard and getting some injectors.. or at least one... Then changing out one at a time and soaking the dirty one in a parts cleaner....

How many miles do you think I should go on veg oil before cleaning injectors..
I went 100 today... my first 100...

It's a good question and I think it will vary greatly depending on oil quality and driving style, etc. When you check your valves, pull an injector and see.
