I was wondering if there is any reason not to do this? I was going to run two tanks with a arctic fox in one. What are the thoughts?

I'm assuming here, because i don't know much about 3116's but I believe those have EUI's in them, and I think the oils will destroy the injectors and their expensive cat parts. Older diesels with mechanical injectors are the way to go for running waste oils.

Just my 2cents

it is a all mechanical engine, I know cat has a 2 micron filter and not sure how that would work with wvo. I have sseen in other posts that wmo is a bad ideal in them.

a filter that small (m35 uses a 6 micron) your going to clog it right up. With my old deuce I would just dump the WMO and ATF right in the tank non filtered and I would have to change fuel filters every 3k miles. With a 2 micron its going to be more like 500 or less. The general rule is the 6.2 and the cat engines don't really like WMO too much. Yes it will run but what kind of other things are going to get hurt.

I am also interested in doing this. I work at a car dealership and have a convenient and un-ending supply of WMO.

Assuming that heated and centrifuged WMO get's out anything larger than 1/2 micron, can you see any down side to it?

I was about to pull the trigger on a centrifuge this week....... but I really didn't want to be the first to WMO a 3116.

I know of a guy who runs this kind of oil through an old 7.3L Powerstroke (different engine I know) and it works ok. With the PS not being a "multi-fuel" it still burns it, don't know why the 3116 wouldn't but like I said with it not being the same engine you may get different results.

I've spent a lot of time looking at threads on other sites where guys run WMO and it really runs the gamut from guys that have had zero issues, to guys that are morons and have constant issues. There were a bunch of cummins guys taking pictures of their carboned up injectors, but I didn't see any injector failure complaints from the powerstroke guys. I believe the CAT shares more commonality with the PS than anything else when it comes to injector design.

I would only want to run 50/50 wmo diesel. I'm not trying to be a champion of free fuel...... I just want to drive my truck more for cheaper.

WVO or WMO?

I see these two interchange a lot. I'm not sure I can always catch the difference in application. But I believe there can be a BIG difference in the outcome. I'm by far anything close to an expert on the subject and I don't have any experience with WMO at all. That all being said...during warmer weather I burn WVO mixture in a Cummins. I even use a mix in John Deere and New Holland farm tractors. If any concernable difference...there maybe a slight loss of power. The WVO is first filtered through a cotton filter to remove all the big stuff such as the french frys and such, mixed with diesel fuel, then power filtered down through six micron filters in a pump system. Please, help me by keeping the two different fuel types seperate, while I learn what I can do and what will harm what I'm trying to use them in. Thanks a bunch for all your experiences.

Myself, personally... I would be a wee bit leery of running unprocessed (unesterified) WVO/UMO in a nice-almostnew-shiney-cat. With that being said, I did a little digging a couple months agao on CAT's stance on biodiesel -This is what I had found in an RV forum (Unfortunately I cant remember the URL, but the PDF they had supplied gives this document# SEBU6250-14 in the upper left & is excerpted from "Caterpillar Machine Fluids Recommendations":

[FONT=Arial,Bold]
Warranty and the Use of Biodiesel in
Caterpillar Engines​
[/FONT]
Caterpillar neither approves nor prohibits the use
of biodiesel fuels. Caterpillar is not in a position
to evaluate the many variations of biodiesel and
the long term effects on performance, durability, or
compliance to emissions standards for Caterpillar
products. The use of biodiesel does not affect the
Caterpillar warranty for materials and the warranty for
workmanship.
NOTICE​
[FONT=Arial,Bold][FONT=Arial,Bold]
Failures that result from the use of any fuel are
not Caterpillar factory defects. Therefore, the cost
of repair would NOT be covered by a Caterpillar
warranty.​

[/FONT][FONT=Arial,Bold]
Recommendation for the Use of Biodiesel
in Caterpillar Engines​
[/FONT]
For Caterpillar ACERT Technology engine model
numbers C7, C9, C11, C13, C15, C18, and also
for Caterpillar 3046, 3064, 3066, 3114, 3116, 3126,
3176, 3196, 3208, 3306, C-9, C-10, C-12, 3406,
C-15, C-16, C-18, 3456, 3408, 3412, 3500 Series,
3600 Series, CM20, CM25 and CM32 engines,
biodiesel that meets the requirements that are listed
in the Caterpillar specification for biodiesel, ASTM
D6751, or EN 14214 are acceptable. Biodiesel may
be blended in amounts up to a maximum of 30
percent with an acceptable diesel fuel. This blend is
acceptable provided that the biodiesel constituent
meets the requirements that are outlined in Table 15
prior to blending. In addition, the final blend must
meet the requirements for distillate diesel fuel that
are listed in Table 13.​
[FONT=Arial,Bold][FONT=Arial,Bold]
Note:​
[/FONT]​
[/FONT]A complete Caterpillar S·O·S Services Oil

Analysis program is recommended when
using biodiesel blends of up to 30 percent.
[FONT=Arial,Bold][FONT=Arial,Bold]
Note:​
For blends of biodiesel above 30 percent,
contact your Caterpillar dealer for guidance. A
complete Caterpillar S·O·S Services Oil Analysis
program is required when biodiesel/biodiesel blends
above 30 percent are used. Biodiesel/biodiesel
blends as used in the engine must meet the
requirements that are stated in the “Caterpillar
Specification for Distillate Diesel Fuel” in Table 13.
For Caterpillar 3003 through 3034, 3054 and 3056
engines, biodiesel that meets the requirements that
are listed in Caterpillar’s biodiesel specification,
ASTM D6751, or EN 14214 may be blended with
an acceptable diesel fuel. This blend should be
a maximum ratio of 5% biodiesel to 95% of an
acceptable diesel fuel. The biodiesel must meet
the requirements that are listed in Table 15 prior to
blending. Use of more than a 5% biodiesel can cause
premature failures. The repair for these failures would
not be covered under the Caterpillar warranty.

[FONT=Arial,Bold][FONT=Arial,Bold]
Note:​
When biodiesel, or any blend of biodiesel is
used, the user has the responsibility for obtaining
the proper local exemptions, regional exemptions,
and/or national exemptions that are required for
the use of biodiesel in any Caterpillar engine that
is regulated by emissions standards. Biodiesel that
meets the requirements that are listed in Caterpillar’s
specification for biodiesel, ASTM D6751, or EN
14214 should pose no problems when blended
with an acceptable distillate diesel fuel at the
maximum stated percentages, however, the following
recommendations must be followed:

[FONT=Arial,Bold][FONT=Arial,Bold]
Recommendations​
[/FONT][/FONT]
•​
The oil change interval can be affected by the use
of biodiesel. Use S·O·S Services Oil Analysis in
order to monitor the condition of the engine oil.
Use S·O·S Services Oil Analysis also in order to
determine the oil change interval that is optimum.

•​
In a comparison of distillate fuels to biodiesel,
biodiesel provides less energy per gallon by 5% to
7%. Do NOT change the engine rating in order to
compensate for the power loss. This will help avoid
engine problems when the engine is converted
back to 100 percent distillate diesel fuel.

•​
Compatibility of the elastomers with biodiesel is
currently being monitored. The condition of seals

and hoses should be monitored regularly.

•​
Biodiesel may pose low ambient temperature
problems for both storage and operation. At low
ambient temperatures, fuel may need to be stored
in a heated building or a heated storage tank. The
fuel system may require heated fuel lines, filters,
and tanks. Filters may plug and fuel in the tank may
solidify at low ambient temperatures if precautions
are not taken. Consult your biodiesel supplier for
assistance in the blending and attainment of the
proper cloud point for the fuel.

•​
Biodiesel has poor oxidation stability, which can
result in long term storage problems. The poor
oxidation stability may accelerate fuel oxidation in
the fuel system. This is especially true in engines
with electronic fuel systems because these engines
operate at higher temperatures. Consult the fuel
supplier for oxidation stability additives.

•​
Biodiesel is an excellent medium for microbial
contamination and growth. Microbial contamination
and growth can cause corrosion in the fuel
system and premature plugging of the fuel filter.
The effectiveness of conventional anti-microbial
additives when used in biodiesel is not known.
Consult your supplier of fuel and additive for
assistance.

•​
Care must be taken in order to remove water
from fuel tanks. Water accelerates microbial
contamination and growth. When biodiesel is
compared to distillate fuels, water is naturally more
likely to exist in the biodiesel.

the engine must meet the requirements that
are stated in the “Caterpillar Specification for
Distillate Diesel Fuel” in Table 13.​

NOTICE
The footnote is a key part of the “Caterpillar Specification​
for Biodiesel Fuel” Table. Read the footnote.

Below they give a fairly large table of spec's used to quantify "quality" biodiesel fuel that they say is kosher, most of the ASTM spec's look fairly boilerplate to me (Keep in mind, Im no petrochemical engineer here) like fairly standard diesel spec's, for the exception of the "Esterification" field (Obviously, since this is specific to biodiesel), which they have spec'd out at 98% & the "Methanol Content" field, which they have spec'd out at 0.2% Max (Since this is part of the catalyst used to transesterify the oil).

I personally wouldn't do it unless it was and emergency but a bio blend properly filtered should be ok. because of the carbon in used engine oil I would not do it period. The other thing to remember is your fuel system is intended for a certain viscosity. get your fuel too thin or thick bad things happen maybe not immediately but over the long run the money saved on using a free alternative fuel will be gobbled up buying fuel injection components. in the past with my b series cummins I have bought ve injection pumps and injectors because of this. my truck is my bread and butter I cant afford to be working on it when I can be working on some one else's for money
