I searched but did not find a answer for this. We have about 4gals of WVO hear from our own deep fryer. Would it be perfectly fine to filter it out and just dump it in with a tank of diesel? My dad might be picking up a Duramax in the next few months and I might just take the 89 6.2 and fix the frame and some other little stuff on it.

I want to look into where I can get WVO,but I am pretty sure I can get a good amount of it to make it worth while. With the WVO I just need a heated tank in the bed with or with out heated lines? And the truck can be run on straight WVO aslong has it is started and shut off on Diesel right? Also what are you guys running to filter the oil? Do you just have a setup up that pumps out of a tank/barrel and thru some filter and then into "clean" storage barrel?

You'll want to run a real heated setup for WVO. Skip the "heated tank" and go with a heated tank pickup - just heat the fuel you need to. You'll want a flat plate heat exchanger - and maybe some electric heat (a glow plug heater or a VegTherm). Being in Maine, you'll want to run some HIH (hose in hose) to keep the fuel liquid on it's way to the engine. For a filter, the Racor marine filters work pretty well - I've got a 690 in my truck. Use a good electric gear driven pump to push the WVO from the tank forward - that'll keep your air bubble problems to a minimum. It would be good to put fuel pressure and a fuel temperature gauges into the mix as well.

Filtering - you'll want to filter well when you get the oil. Settle it as long as you can, then run it through a decent filter media - I use bag filters suspended in oil (don't try hanging them above the container - they will stretch) and filter to 0.5 microns. To save on filters, I typically use a 10 micron filter initially - before settling. Heat the oil up to ~ 120 *F and let it slowly cool - to settle out any water.

Be careful with metal tanks up there! Condensation is a problem - and you'll want to check for it regularly. Over time, it can make for a considerable amount of IP-damaging water in your tank.

Thanks for the info, Would it be fine to dump the 4-5 gals of WVO in with the diesel after its been filtered? Its been in the mid 60s here,so I doubt it would gel,plus if it is mixed into a 1/2-3/4 tank.

I never recommend just dumping WVO into a tank of diesel. The oil and the diesel won't mix very well in that case, and while it wouldn't likely hurt anything if it's plenty warm, you could end up getting a full slug of oil into the engine.

It is better to premix the oil with some diesel to get the viscosity down closer to regular diesel, then dump it in. You don't have to get too crazy; just a couple gallons of diesel in with your 4-5 gallons of oil is probably enough.

Thats what I was saying just mix it with diesel in a can and then dump it in.

if the oil is clean and dewatered, 4 or 5 gallon in an almost full tank will be fine, put it in and shake it up some.

where do you get the .5 micron filters?

I want to know what part of Maine you are in. I guess I want to move north. I am in central Maine and it was 35 this morning. This would be way to cold to run WVO without a heater. If the oil settles overnight and you get a slug of straight veg. oil I would not expect the engine to run.

No. It's not worth the $12 in "savings" you think you are getting. If you are going to run veggie, then you should really consider a kit in order to get things toasty warm. You $12 "savings" might cost you an IP, or worse.
