I have concluded this is like a political battle... I see articles that say it does no good at all and I see restoration articles of 50 year old vehicles that have been disassembled with no rust on the bottom when there should be.
The anti oil side says it isn't made to stick, it is environmentally bad because it does roll off on to the ground, and it really does no good because when it is off the rust can still attack.
The other side claims with a thick coat of used oil and a trip on a dusty road about once a year your frame will not rust.
Obviously the correct way would be to remove the frame, clean it, blast it and coat it with a product similar to the popular POR15 if not POR15. Man that is a lot of work!
I know when I was younger and worked in a "gas station" we took the drained oil, saved it and used a big paint brush to apply it to our frames. It was just "what you did". I never kept any of those cars long enough to prove or disprove its effectiveness.
Does anyone have any real data proving it helps or proving it harms?
To be honest, I have never heard of this before. But I can see that it would be effective. Plenty of things in my profession come coated in oil to prevent corrosion. An oil coating will not just come off on it's own, it would need to be cleaned off. Usually with a cleaner of some kind, usually IPA. But applying it could be a pain nowadays couldn't it? And yes any spill would be considered toxic. In todays world I can't see this a valid option as I am sure that there are dedicated coatings that would be easier to apply and last longer. But I can see the logic behind the oil coating.
