if I wanted to add some wvo to my diesel just for the lubrication and to quieten the thing down some? A friend of mine has a fish restaurant and says I can have all I want of the waste oil so I was just wondering what all has to be done. i have looked at the threads but see either bio threads or 100% veg oil. I just would like to add maybe a couple gallons to each tank if that would do any good. If not, just tell me that LOL
be sure to run it through filters before putting mixing with diesel , filter it down to around 1-5 microns and then take 2 gallons and mix with 2 gallons of diesel in a can or bucket before putting in your truck !
But in my opinion, just dumping veg oil in your tank has too many potential problems. The biggest one being the risk of having it settle to the bottom of any part of your fuel system, and gumming things up. This is particularly an issue in cool weather. There are some who blend fuel and have it down to a science and can make it work, but there's a method.
Well, I think we are going to learn how to brew our own biodiesel. My wife and both parents are pharmacist so surely to goodness I can figure this out..
I think it's the best route. You will do fine as long as you've got the motivation, space, time, and oil source. You have plenty of support here along with some seasoned veterans. It's complex, but not complicated. Best of all, it's a worthwhile, good thing to do.
Burning unheated WVO is a bad thing for your fuel system and your motor. In my picture album, I posted a chart with a viscosity table comparing diesel and veg oil - it doesn't come close until oil is at 160*F. This means it won't combust completely and will gum up your injectors, rings, etc. Also, with normal fuel blow-by on a cold start, you'll get veg oil mixed into your crank case - it forms a mayonaise-like substance inside; not good.
If you're looking for lubricity only, run a B5 blend, don't blend in WVO. In cold weather, it will drop out of the fuel and cause you the problems above. Bio is a lot more work and it costs more over the long run with the variable cost of methanol and the chemicals you need on an ongoing basis. But, bio shines if you do a lot of short trips or have multiple rigs to feed. Plus, you can run a B20 blend in your home heating oil if that's how you heat your home.
If you go the WVO route, convert your rig to a good heated 2-tank system like the Vegistroke. I'm not an expert, but I've been burning WVO in my '02 Ex with a modified V3 system for 2 years without major incident.
Either way (bio or WVO) if you have a good oil source, I don't think you can go wrong.
