hi,
i found some jugs of vegetable oil by a dumpster at a construction site. i'm pretty sure they oil hasn't been cooked, based on the face the boxes were sealed. it's a hot summer, can't i just run this straight in my fuel tank? i'm already running commercially made B99 biodiesel, but it's 45min each way to fill up, so any amount i can stretch, and for free, i'd like to do.

thanks!

As SVO, I would not do it. Not worth the risk to me.

Now if you are going to blend it at 20% until it's gone, that would probably be harmless.

First thing I would do is check to make sure it is just vegetable oil, and nothing else. Then if you want to use it go ahead, but I agree use up to a 50/50 blend depending on ambient temperature. While using it straight will work, unless it is heated to about 180 degrees or so, it is pretty thick and the IP will not be overjoyed until it warms up. Plus cold VO tends to not burn completely and can lead to gummed up rings and deposits over time.

I run a two tank system with a flat plate heater and have over 80,000 miles on filtered WVO so far and have had good results. I have started the car on cold WVO with an ambient temp of about 45 degrees before (when I stupidly forgot to purge the lines before shutdown) She started kinda hard and ran really rough for about a minute, but she started.

This is what I would suggest:

1) If you are doing short trips only then do as others say. 50/50 or 40/60 SVO. It does not matter.
2) If you are doing a long trip then dump it in 100% in the middle of the trip. The engine is hot and it should have no problem. Thin it out when you are almost at destination. Similar to how a 2-tanks work.

well, i realized it was indeed used veggie oil, it had food bits in it. i decided to try filtering some for fun with just whatever materials i could find nearby, it was pretty funny:

Actually an old T-shirt, or old blue jeans make a decent gravity filter. So do coffee filters

If meat or chicken was fried in it,you can get a skin that developes on the tank.

interesting, wouldn't biodiesel clean that out?

Poly (WVO polymerization) experiences vary widely from

-Mine -meh, cleaned lots of loose 'chicken skin' out of my 2nd tank with a 2 tank system that broke the active metal taboo of the frybrid community- mild steel tank, copper fuel lines.

-Oldsinner111 has shared some poly nightmares, nasty fuel filter clogging

- frightmare- dead engine anecdotes from polymerized wvo ring blow by in the crankcase

A friend of mine says he runs 100 wvo in an unmodified 190D until it's too cold to pump, then diesel. He's at several years of use like this now.

You're four times

a cell phone.

www.kiva.org It's not like there's anything wrong with feeling good, is there?

At 160 degrees F vegetable oil has the same viscosity as really cold diesel. So at that temp the injectors will spray it with the same pattern as diesel.
Cold VO will not spray in a good pattern and some will dribble out unburnt and end up on the cylinder walls, then impact the rings in their grooves with carbon, then the rings will not keep the unburnt VO from contaminating the sump oil. The effects can take from 20k to 50k to be noticeable.

If you burn it straight or blended, carry some (not just one) extra fuel filters with you.

Chúc bạn mau phát tÃ*i nha

What a mess! Pouring through a bath towel is not proper filtering.

I hope your mom clean up the mess afterwards. I don't think it was funny.
