Over the past year I have accumulated 2 big pails full of used oil, (Engine oil, gear oil, and whatever else is in the bucket)

Is it feasible to re-use this oil for oil spraying the undercarriage of my truck? I'd run the oil threw a filter first, and than spray it on in my driveway (I have a gravel driveway)

Pros? Cons?

Is this for rust proofing or for mudding?

I don't think there are too many minuses for doing that as long as you don't get any on the ground.
Use a tarp or something to be sure you contain any spills or runoff and let sit overnight.

I personally wouldn't do it because there are other better, more effective alternatives out there.

EDIT: Here is another link I found on this (says not recommended):

Both I guess. Rust proof the undercarragie and maybe spray it into the doors and quarters.

I wouldn't spray used oil on the driveway. Too many toxins will taint any groundwater. Besides it may be illegal.

That would be illeagal in the U.S. Used oil may contain Dioxin, and also petroleum is a KNOWN cancer causing agent. If you are comfortable spraying a carcinogen onto your driveway I say go for it.

call the EPA and tell then what you are going to do first

I've heard of folks using an old garden sprayer to oil down the inside and outside of their frames periodically for rust prevention. Supposed to work fairly well, albeit a bit messy.

I know here in the states, using engine oil for dust control is not allowed anymore. Down near a gold mine we drive past near Death Valley NP, they oil the road with a biodegradeable mix of water and used vegetable oil. Smells a lot like french fries going down that stretch of road. One time we got caught behind the oil truck and our rigs literally had an inch of oily mud plastered all over. Dreaded the thought of having to wash that off. That night in camp, it rained and the next morning, the rigs were spotless, that oil/mud mix just washed right off in the rain.

When I grew up in PA I knew of a garage that used a mixture of used oil and acetone for rust proofing. They sprayed it through an old paint sprayer on the undercarrage. It works pretty darn well.

The EPA is in the US, he is in Canada.

doesnt canada have some sort of EPA

Just because he's Canadian still might not make it a good idea to expose himself and others to a possible health hazard.

Most provinces have a department of environment but there is also a federal version as well.
The provincial would be the one to contact because environmental laws may vary by province.

While I doubt anyone would come and fine you for doing it, it ranks about the same as pulling off your catalytic converter.

The term "EPA" is specifically a US agency.

umm kay? Just because he is Canadian..? The way you worded that entire sentence sounds bad..to me anyway.

I think if he takes the proper percautions in doing it, (laying down a tarp, etcc...) I think it would be fine.

To clear a few things up. First off I would put down a painters tarp to catch all the oil, (The reason I said I have a gravel driveway was for the over spray and stuff... Its not like I was going to dump the oil onto the gravel guys)

My thoughts where this. Filter the used oil to get any large particals and dirt out, Load the oil into an old paint sprayer and coat the undercarrage, inner doors, fenders, and rockers, let it sit for a few hours and clean up the mess.

this beats paying $95 for an oil spray at the local place.

I can't see how this would be differant than getting a professional oil spray other then the fact its used oil, and I would be doing it myself.

As for the used oil being toxic and cancer causing I will look into that a little further. but other than that so for it seems like it will work ?

thanks for the info so far guys.

I was referring to the comment about Canada not having as many restrictive laws as the EPA has here but yeah,I look down on Canadians anyway cause they're sooo different than us.
