Not on the older mechanically injected diesels. I have spoken with more than one person that was dumping the vegetable oil directly in the fuel tank.
On electronic fuel injection pump vehicles, you must do what you describe.
I looked into this as at the time. I had a 1995 GMC turbo diesel C2500 Suburban with electronic fuel injection.
I seen the neighbor pour it directly into the tank and drive away.
Now, he had quite the filtration system in his garage that removed all particles less than X (I can’t remember the number). I also remember seeing him pouring the vegetable oil into buckets through cheesecloth in a funnel.
So, you are correct about the newer electronically fuel injected vehicles.
My plan is to just buy the diesel for this old 300D. I don't think it will be driven enough to get any monetary benefit from anything else.
