Crude oil mixed with diesel?

[cowsrus]

I heard this at a recent family gathering, "the new diesel does not provide very good lubrication so some people were mixing some crude oil in with it for lubrication purposes." A couple of my relatives have been doing this . Have any of you guys ever heard of this? I think they were referring to crude, but it could have been regular motor oil.

 

[Jim62]

I put a cup full of regular motor oil in the tank whenever I happen to think of it. It was recommended by an old trucker for the detergent value in the oil. His contention was that the extra detergent would keep the injectors and such clean. I guess it might work, as I haven't ever had any problems in that area. Don't have any idea about the lubrication part, but it sounds reasonable--surely won't do any harm.

We use marvel mystery oil or automatic transmission fluid(Dex tron II) in our diesels quite often. Marvel mystery has the direction on the container. It is not expensive.

I have heard of alot of people using marvel mystery oil. Although I haven't tried it yet, they swear by it.

My cousin is a tractor dealer.

He was stanidng on my place one day and he looked at my old ford 3610 and asked me if I was using a fuel conditioner.

I said no.

He said where are you getting your fuel.

I said from the local gas station and I buy it ten gallons at a pop in cans.

He told me that for all but the newer engines ( maybe the last four or five years) the new low sulfur fuel did not have enough lubricity and the engines would wear faster.

I get fuel conditioner from either walmart or the local napa dealer. Pretty cheap. A little goes a long ways.

Can not comment on the other ideas posted here as i have not tried them.

we use lucas fuel treatment in all of our trucks and tractors.
We also use thier other products, and we have had great results with them especially the oil additive.

The whole "dumping a cup of oil in the tank" is from the old school, and works well for older equipment (although I personally believe the new fuels have sufficient additive in them). However with the newer diesels this is an absolute no-no. The nozzle holes are simply not large enough to properly allow heavy oil to pass through them and they will wear faster.

If you really feel the need to treat your fuel, use a proper conditioner.

Exactly what I use. Good stuff.

 

[Brute 23]

I use the Lucas fuel treatment in my vehicles also.

We use the fuel treatment, oil additive, hydraulic additive, gear oil, gun oil; these are the ones I can think of right now

the most popular additve to replace the ulsd lubricity is to use 2 stroke oil from walmart. the super tech. NOT the synthetic. about an oz /gallon. cannot use it in 07 trucks or newer as it will clog yer particulate(soot) filter and viod yer warranty.

marvel is a decent cleaner but not at all a lubricant. is is mostly naptha. i can hook ya to a link about all kinds of tests done on different additives if you like lemme know.

newer trucks(maybe 00) and up cannot use trans fluid or reg oil in the fuel as like dia cat. said they cannot pass it thru the inj tolerances.

the new trucks are EXTREMELY peticular about clean diesel and additives. 5 micron filters and 26000 psi rail press. only takes an invisible spec of dirt to ruin an inj

diesel beef is bang on with the 2 stroke super tech walmart oil. It'll lubricate the whole fuel system, quieten down the injectors alot and increase your mpg by 1-2 mpg. Also is an anti-gel and makes it easier to start the truck in the morning. Also, it SMELLS like the old diesel. Use one oz. per gallon. Walmart sells a 500mL/16 fl. oz. small bottle of it. MAKE SURE IT SAYS MARINE ON IT!! because then it is ashless and won't leave deposits in your cylinders. I keep a bunch of bottles in the truck box and dump a full 16 oz. into my 18 gallon tank when I fill up.

I use the Lucas Heavy Duty 85/140 Gear Oil in the cutter bar of my hay cutter and have had no trouble so far.

 

[Smith1000]

The guy at the pump shop here says to mix in some transmission fluid with diesel.

 

[dieselbeef]

he is wrong!

actaully depends on the truck but atf is not a good additive for diesel anymore. if yer gonna do it add the walmart supertech. its been researched and proven to do the job

what kinda truck is it. an older one might tolerate the atf but thats a myth from waaaaay back when the inj pumps could handle eating dirty motor oil...another big non-no


keep in ind the price of repairs on these newer vehicles. i could be spewing myhts forht just like anyone else but diesel performance ia bit of a hobby and i wouldnt steer ya wrong...i would never use atf in my truck...maybe the pump guy does yer repairs???

Oh man I have to do it again . Sorry Rod. The oil added to diesel is diluted to such an extent the injectors won't know the difference. Diesel is similar to kerosene and it very quickly dilutes any oils. Even use it to dissolve tar spots from the duco of your car. The new diesels have no sulphur added and what happens here is that the O rings harden and crack requiring earlier replacement .

you couldnt be more wrong. its not the oil its the dirt in it thats bad. new diesel does have sulphur at less than 15 ppm(15?) anyways its way low and ill find out if need be but the new trucks are built with this in mind since about 05 so the oring thing is wrong as well.

if you put waste oil in your tank the truck will over porduce soot and clog your dpf(thats diesel particulate filter for you kids) . if it does try to burn it off typically it will go over temp due to the hgh amt of soot burning off and put the truck into limp mode.

take yer chances but if you start hearing that funny knockin noise..just remember that injector job now will cost you about a grand for parts on a new cummins

its yer truck to do as you please but when yer broke down in the middle of the desert youll always be wondering ''if its not that waste oil in my tank''....it serves no purpose in a less than 5 yr oil diesel engine and it WILL damage it

Diesel is similar to kerosene and it very quickly dilutes any oils.

Dilution is different than being able to break down a heavy oil molecule, which diesel fuel cannot do. Running heavy oil in new injectors is like extrude honing, especially if the truck sits for long periods. The heavier oils will separate out and sink to the bottom of the tank. Fire it up, and you'll be extrude honing your injectors until you start moving and mix the tank up again.

Use an appropriate fuel additive. Not sure if it was this thread or another one, but they tested several additives, including two stroke oil, and there were several inexpensive additives that easily outperformed heavy oils.

You bought a $50,000 truck. Don't cheap out with used oil in the fuel.

well said...but im not sure even the 2 stroke is good on a truck with a dpf

 

[tytower]

"dumping a cup of oil in the tank" was mentioned above and the title of the thread is Crude oil .....

you couldnt be more wrong. its not the oil its the dirt in it thats bad.

Err I assumed it would be clean oil -mustn't have read the posts properly

new diesel does have sulphur at less than 15 ppm(15?) anyways its way low and ill find out if need be but the new trucks are built with this in mind since about 05 so the oring thing is wrong as well.

Legislation here is under 500 ppm

Lubricity

Refinery processing of diesel to reduce the sulfur level can have the undesired effect of reducing the natural lubricating properties of the diesel, which are essential for the good operation of fuel system components such as fuel pumps and injectors.

A diesel lubricity specification has been introduced as part of the mandatory national fuel standards, which all diesel must meet.

Impact on Seals in Fuel Pumps

The production of Low Sulfur Diesel leads to changes in the composition and chemical properties of the fuel, other than sulfur content. In general, these changes are expected to be minor. However, there may be certain changes that could affect engine fuel systems. It is prudent to be aware of the possible effects on engines of such changes and take preventative maintenance action.

Some types of engine seals and O rings can react to changes in fuel composition by swelling or shrinking.

In current generation engines, and engines supplied generally post 1994, fuel system seals and O rings are made of FKM (also known as Viton), which is not affected by this process.

Fuel systems more than 8 years old may have seals made of nitrile rubber (also known as NBR or buna-n), which is not as resistant to changes in fuel composition as Viton.

When fuels of different composition are used, old seals made of nitrile rubber may not be able to adjust properly, and this may exacerbate the cracks or stresses already present due to the natural aging of the rubber. If this occurs, the solution is to replace the seals with new ones; after this, the problem should not reoccur.

As a consequence, it is recommended that owners of older vehicles with older nitrile rubber fuel system seals consider changing any such suspect seals at the next maintenance.

Yep agree on the new motors
