Can i put old motor oil,atf ,frying oil and gear lube in my 6.9? If so, how do
I filter it?Do I need to mix it with fuel, or can I run it strait?
sorry but I am a :-newbie to this hole alternative diesel fuel thing.

ATF yes, fry oil needs to be filtered and heated and would need a WVO conversion... I wouldn't put motor oil or gear lube in it

How do i do the WVO conversion?

don't know all the details but...
You filter waste veggie oil and then use one of your tanks for veggie and one for petro diesel. The veggie oil needs a heater to warm it up and make it thinner and easier to burn/pump.
You start the truck on petro diesel, then switch tanks over to veggie once it's warm, then you need to switch back to petro diesel the last couple miles to flush out the veggie oil.

There are some other things you need... but that's the basics. You can buy kits to do it.
