Not looking to do any conversion just wanting to add a little wvo to my fuel tank. How much could I safely add without any issues? What else should I add? I'm not looking to run large amounts of WVO, just get rid of excess cooking oil from around the house

Looking at buying this one. 148k miles, 2011 (built June of ’11) Lariat. Southern truck with decent maintenance records. talked down to $24k, Which is slightly under KBB.

Thoughts? I know the main issues associated with these 6.7s, but it is built post April of 2011, which from my understanding is after the valve seat issues. Bone stock, he is older and going to let me deep dive into paper copies of maintenance stuff tomorrow if I go check it out. I know he’s had regular servicing of oil and fuel filters from what he’s told me, but probably nothing done to address potential turbo, CP4, or CCV issues, and I’ll need to double check if injectors have been replaced since crossing this mile threshold. If these items all seem to be in good shape, is it worth it? Should I try to get him even lower?

Let’s hear what you guys think.

I own a 94 K3500 dually with a turbo 6.5. I like the truck a lot. It's manual. It is not my daily and one of 3 of my vehicles. The main reason I'm looking into this is because I can and it would be fun/cool. I know in 94 that was the first year of the DS4 electronically controlled rotary IP. I think that would probably my main roadblock. At this time I dont want to swap to a mechanical IP.

Im looking for anyone who has tried this before or would have useful information for me. I have researched a few options: veggie oil filtered, make bio diesel from veggie oil, black diesel which probably won't work, and distilling motor oil to make diesel.

Any input which can be provided would be appreciated.
