The good news -- it's free; a sort-of dino version of WVO -- used aviation motor oil.
Just go to a local airport, look for a repair station, and ask for used aviation oil from piston
engine aircraft. Avoid the oil used in turbine and diesel aircraft.
Converting Your Car to a Waste Aviation Oil Burner
All you need is a "primary filter". There are various versions,
including Mercedes' primary filter. The one I recommend is
the small glass in-line filter sold at Parts R Us stores as an in-line
gas filter for hot rods:
(universal Glas Kraftsfilter)
The elements are replaceable but are just as easy to clean each time
they're taken apart.
What Can Go Wrong
ONE MAJOR ISSUE - IT CAN'T BE USED ON A CATALYTIC CONVERTOR CAR DUE TO LEAD!
One time, after dumping about a gallon of this stuff in my tank at the
airport, the car (a 123 Mercedes) showed fuel starvation. For a second
I was wondering if I ruined my injection pump or something. Then I
figured it out. When I got home, I just opened the primary filter and
wiped off a bunch of old leaves, bird droppings, mouse nesting
materials, etc. from the filter screen. The increased viscosity of
the aviation oil seemed to disagree with a bunch of weeds and dead bugs in the filter.
That's all. That's the reason
I recommend one of those primary filters. They're a good idea.
The used aviation oil is also useful should you need to add fuel
lubricant for whatever reason.
This stuff has a lot of lead, so it will deteriorate the catalytic
converter.
I suppose it can gel-up in cold weather, although I never experienced it
personally. For one thing, local fuel will be "lighter" in the winter.
If winter flow is a problem, add some kerosene or Diesel 1.
Why this Works
Piston aircraft engines use ashless detergent motor oil. Aircraft
mechanics refer to their detergent oil as "AD" and non-detergent oil as
"mineral oil" but the important part is that motor oil used in piston
aircraft uses ashless detergents (or in the case of mineral oil, no
detergent). So it will burn quite nicely in a diesel car.
Turbine oil and diesel oil are not suitable. In the case of turbine
oil, the detergent may be ash-producing (I'm not sure). Diesel aviation
oil is the stuff we use in our cars, which is definitely ash-type
detergent.
