Give us your General FAQ's!

[Fordnut74]

One of the areas I know we need to work on is just general Knowledge. Here is your chance to ask the questions you couldn't find answers for on our site. This thread will be for WVO questions in general. I will start another for system specific FAQ's. I want to know what you want to know! When listing questions please list them out to make it easier for me to copy and paste. Thank you!

When is oil to old to use?

[greasedltn]

I've always been told, about 6mos. But I just go by my nos. If it smells like rotting oil, it is. I never let mine sit more than 3 weeks after I collect, if I don't use it all by then I sell it to the local biodiesel plant.

What happens if you run oil that is too old?

Oil Types

What are the best vegi oils to use and what are the worst?
ie peanut, sunflower, canola, 100% vegi, etc.

[Clay]

does new oil have to be "de gummed" before using it?

[Marv]

What are some simple tests I can run to see if I have any contaminants (boil out) in my oil?

How can I tell if my oil is "clean" enough?

[greasedltn]

Hooter if the oil is too old as far as I know it could have bacteria which is not good for any fuel system, and if I understand rite, the oil doesn't burn properly and can coke the injectors. Not good either way.

Triple M the only oil I stay away from is hydroginated, since hydro is water I keep it as far away as I can. The diesel engine was designed to run on penut oil, but any oil is good if it's clean.

Marv, boil out is a good test for water, but that's about all it will tell you. If your donaldson filter stops up quickly, you didn't prefilter enough. Other than that you need lab equipment to find other contaminants.

[FastCote]

Is condensation in the tank an issue? How much condensation builds up (summer vs winter)? Should I drain the tank periodically, and if so, how often?

[FastCote]

My truck runs roughly at idle. Is this expected (it is heavily tuned, + 175 HP)?

[greasedltn]

Condensation is not a big issue, I still try to keep my tank semi-full as not to draw in too much outside air. The rough idle needs to be looked into. A friend of mine had a 6.0 with 165 tuner from TSP and idled smooth. It may be the tuner or something with your injector seals or HPOP. If you can detune back to stock or mild tune, try that and see if it smoothes out.

I disagree with this. Can you tell us why its not an issue to be considered.

could be early injector trouble... could be tune as mentioned. Either way I would stop burning oil until I found out what it was.

[greasedltn]

Not to say water of any sort is not a concern, but the small amount of condesation would be trapped in the donaldson and unless the humidity is near 100%, you shouldn't get much water in your oil.

Humidity above 80% is what i consider high and that puts alot of moisture in the air. Where i live we see 85-90% humidity several days of the early summer as well as the early fall and you can bet your going to see some substantial condensation in that kind of atmosphere.
