Burnin used motor oil -N- Stuff Again..

I would think it'd be super thick.  Does WMO thin out at temperature like WVO?  I read things about people putting gasoline in to thin it, but that's a baaaaaad idea.

are there any long term affects like gunk?  I'm definitely interested in getting somre more info.

all oils will thin out at the right temperature.  andy2 helped me install a pump with some 10w30 oil in it, and it started up cold no problem.  engine oil has the effect of lubricating the injection pump properly, so you won't damage the internals.  however it might not properly atomize, so there could be some potential gunk buildup.

You can also modify a juicer.

Going to be building one of these once my listeroid generator is up and running. Gonna be burning veggie most of its life.

A juicer huh..   Now that's a darned fine idea...

jtanguay, get us some pics of these contraptions!!!!

Let me just butt in for a second and say that I am still running with 10% filtered realitively fresh (only 10 hours in the machine) Cateprillar 10 wt. hydraulic fluid. It has been about 4,000 miles and all is still good. There for awhile, I was doing more like 14% and started getting more smoke which (of course) was more annoying at above 5,000 feet elevation.

When I changed oil (this engine only has like 6,000 on total rebuild) there seemed to be more soot in the oil as it exited the pan. So, I poured about a half gallon of diesel through the engine and let it drain. The soot continued to exit the pan....but, you can do this to an all diesel engine and continue to get some soot.

 My seat-of-pants assessment: more soot, more power, no observed temperature increases, more quiet, still cold starts just fine, and people either pass or back off.

So far about 4000 miles on a 50/50 mix of WVO and WMO..   So far so good.. Took it to Pittsburgh to see Mr. Buffett. Gave it a good servicing before we left....  Oil seemd to be no nastiaer than normal..  Not too bad since I can;t remeber the last time I changed it..  (Remember, the engine is junk, I just don;t care anymore) Changed the air filter and both the diesel and WVO fuel filters too..

Decided to up the ante for this trip so I did about 75% WMO and 25%WVO (I would done 100% but I didn;t have enough decent WMO)..  Filled the diesel tank too, just in case...  Ran like a champ..  Maintained 70 - 75 MPH on the turnpike..  Except over the mountains near Bedford..  I dropped to 65 mph a time or two..  Not bad for 2  larger people with luggage, a grill, gas powered blender, and a cooler of booze...  A rough figure on milage I got about 43 MPG...

The only problem I encountered was when I was switiching back to diesel on the way home.. Darn thing started running like crap...  Screwed another filter on the diesel side and it was good to go...  Go figure

thats how my friend made his centrifuge!!! i gave him my old broken jack lalanne juicer (plastic piece broke  ) but the only thing he used was the base.  it comes with a 350 watt powerful motor (i think the motor has a lifetime warranty???).  it works very well!  one could theoretically get an inverter and filter on site, but it doesn't filter too quickly.  a larger unit would be better suited.  i really like the idea of self containing the whole system though.  using veg oil fuel to filter the veg oil

one thing you'll notice from centrifuge filtering, is that you don't need to change filters as often.  the link above has the right idea, but there are some considerations as adding a spill over top to make sure crap doesn't spill into the clean oil catcher, etc.  the oil gets flinged pretty good and can even spray out from the pressure so it has to be sealed well.  heating the oil makes a huge difference as well.

I use 50% WMO with 50% WVO when I have WMO to burn. I centrifuge it all. I've run 100% WMO before, it's got some blue smoke obviously. It feels about the same power as diesel. WVO doesn't have as much energy as petrodiesel but WMO seems to, which is good.

Food for thought: ATF has used sealer in much of it (used by people to seal leaks) that makes tar babies. I'm afraid of that *** (but I still burn it anways  )

Theoretically WMO should have more power than Diesel, as Oil has a much higher BTU then Diesel does. (because it has passed through less steps of refinement then Motor Oil.) Maybe the reason you are seeing less power is because of the added crap? Or does centrifuging the oil make it cleaner then new oil???

I know with the ford diesels.. a common failure of the CDR valve will essentially make the engine drink its crank case contents.. and then that oil drains to cylinders 7 and 8 (due to intake mani design) and causes those cylinders to run much hotter and destroy valves and HG's quite quickly. Lol.

if you can't properly atomize the oil, then it won't burn properly.  thats why higher breaking pressures are a good idea when converting to veg.  static and dynamic timing is affected as well, further changing the characteristics of how the engine runs.  and yea the motor oil will have more BTU's due to having heavier petroleum oil distillate, but i wonder just how much?  must depend on brand of oil, weight, etc...
