veg oil in diesel

[907DAVE]

I have ran as much as 30% WVO in my rig during the summer months with no negative effects.

This is going to come out sounding super noob like, but I am too lazy at this moment to do more research and figured that you could provide all info..... So when I cook with vegetable oil/canola oil/olive oil/etc. , I can then just drain that off into a jar and pour it into my fuel tank on my 1997 7.3l powerstroke? Because that would seriously be really convenient.

[907DAVE]

Yup, as long as the oil is clean and has no cleaning chemicals in it....pour it in.

How do you make sure that it is clean enough to pour in the tank?

Well, there is a ton of different methods used to filter WVO. Many use a centrifuge style filter, but they are expensive.

I use the "settling" method. First I let the oil containers sit untouched (preferably in the sun) for a few days before pumping through a 50 micron filter and water separator then it goes through a 2 micron post pump filter and into a black barrel. Once the barrel if full I will sometimes add regular unleaded gas (rug), Power Service's conditioner, or whatever else I got laying around...lol. Let that sit a few more days and pump strait into the truck using a 2 micron filter.

Been doing this for the past few years without any problems.

Just noticed your from Palmer, so like me - this can only be done for a few months before temps get close to freezing. You dont want to get caught with this stuff in your fuel tank when it gets cold......that would be no fun.

Fantastic! Thanks for all the info. I'm going to try this next summer.

That's cool, down here you could probably run it 11 out of 12 months. Have you ever tested for an average freezing point?

You must also do a lot of frying.
