Spray oil underneath truck
Want to spray the bottom of my 2005 Ford with motor oil. I have a gravel drive and keeping my truck on it is not great and it is beginning to get surface rust. Can I use 5w30 through my garden sprayer...

Sorry, but you've already lost the battle. Your problem is the rust that is already present. You'll never get rid of it. Anything you do will only seal it in. And every time you throw up a rock off that gravel drive, or that piece of salt you kicked up out on the highway, it will start more rust. Not to mention that nice salt bath you have to drive in all winter will find every possible crevice. A film of oil applied 6 months ago (or 6 days ago) won't stop anything.

I'm going to have to disagree with you on part of this statement, Tim. Products like Ospho or Jasco Metal Prep use phosphoric acid to neutralize the existing rust. The OP is talking about surface rust not body perforating rust that has caused irreversible damage. I have had great success in stopping rust dead in its tracks with phosphoric acid based products. Even products like Fluid Film react with the rust to neutralize it as well as provide a wax like residue protective film.
Again I agree that using motor oil is very irresponsible way to go. It has numerous ramifications even if you don't care about the environment. I also believe that undercoating does little more than create pockets to trap salt and moisture and usually ends up creating worse problems than you would have on an untreated vehicle.
