Old wvo

[Scott88M]

I recently picked up a blue plastic 55 gallon drum of wvo that's been air tight but has sat for 2 years. It's clear and golden.

When I first opened the drum I noticed a paint thinner type smell (the guy mentioned he had dumped in some fuel stabilizers so don't know if that caused the smell) now that it's aired out some it smells just like B99 to me.

My question is do you think this stuff is bad and shouldn't be run at all?

(I understand my truck isn't a "multifuel" but all diesels can run on various oil fuels)

Should I run this? I only plan on dumping it in in weak blends like 90% pump diesel 10% wvo and only this barrel I usually blend minuscule amounts of wmo a gallon here and there.

Thanks for any and all info.

I would not use it at all.

Due to the age and original smell? That's where I was leaning just hoping for more wvo informed people than me.

Because it is acidic.

Just a bit of WVO will break everything loose in your fuel system.

1 quart will clean and clog your filter like you won't believe.

Unless you have run it regularly, forget it.

I ran B99 a lot in the summer (I can get it from a reputable regulated station cheap NOT homemade) is bio less acidic than wvo? (That's an honest question, I'm not afraid to run small mixes of alt fuels but I'm no expert)

I have no experience with purchased bio.

I have tried wvo a couple times and always ended up with issues afterward.

Are we talkin biodiesel or waste vegy oil here? Two totally different animals.
OP, since you said it is clear and golden, I assume you mean biodiesel. Id personally run it is actually production astm bio, just not the bottom of the barrel where stuff settles out to.

It will wash the tank and everything out. Add a gallon and have a few filters ready. Run that tank and then after that I would keep it mixed 50%. It will for sure keep things clean.

Thanks I appreciate the info, I'll look further into the bio I run in the summer. I had no issues with clogging filters but if refining wvo removes the acidic properties then I'm liable to clog now. If not then I SHOULD be already cleaned out. If I do run some I'll wait until I'm prepared with new filters on hand in case of emergency and I'll report back my findings.

Sorry I was typing my last response and didn't see your question. It is wvo that someone had previously filtered but they sold their diesel and I picked up their last barrel. The drum was air and water tight but had sat for 2 years.

Maybe a testing kit will save you money in the long run. A titration test should let you know the amount of fatty acids in you WVO and provide the amount of neutralizing agent needed (lye), if you so choose to.

WVO does not seem to deteriorate as a fuel source. My first batch of WVO sat in the desert for 2 years before I blended it with gasoline at 20%, then filtered it down to 1-micron. It ran fine.

But, if you are going to use new or old oils for fuel, then you need to filter it down pretty good, and run it in warm weather, not cold weather, unless you are experienced at it.

Thank you all for your replies. After further looking I think the wvo I have is still good but like you said it's too cold to run it right now so I'll check it again in the late spring.
