So to summurize everything, Soot = hard metal objects inside my fuel system.

And unfiltered oil in the fuel = very very dumb


i will keep you guys updated on future reprocuissions of my actions if any.

I would not worry about it. I don't think you have done any damage. The secondary filter would have blocked the nasty stuff. Anything small enough to pass thru would not have mattered anyway, that is why the filter is there.

well, that is very true. that does make a lot of sense.

FWIW, the W124 CD for an 87 300 diesel, lists the plastic prefilter as being 600 microns, and the spin-on filter as being 8 or 10 microns.

A true high efficiency 2 micron absolute fuel filter (ie, greater than 90% at the 2 micron level), such as made by Cat or Fleetguard, is in excess of what Bosch recommends for even a high pressure common rail injection system (5 micron final filter).

A little 2 stroke oil added to ULSD can be a good lubricity additive - but I usually only do 8 oz to a full tank, not 2 gallons!:D

I just wonder...... After reading all of the "I tried WVO in my car", or "I tried ATF in my car", or "I used old motor oil in my car" most of the answers are the same...."it will kill your engine sooner or later". Well, based on the time of the original posts, it is now "later". I would think there should be a lot of "killed" diesel engines out there by now, but I have not heard of any.... haven't even heard of a plethora of IPs needing to be rebuilt or injectors dying... Again, makes me wonder........

while I'd not worry about 2 gallons in a tank of fuel ONCE, I'd certainly not try it on a regular basis! the filter is there to remove contaminants that MIGHT be in the fuel... USED motor oil CERTAINLY has MASSIVE amounts of wear particles, from the carbon crystals (soot) to the shards of metal shavings, dirt from the atmosphere, and massive amounts of general crud that a diesel motor produces. the tiny fuel filter is not designed to handle THAT volume of mess, and pumping that through your IP will certainly wear out the pump.
I've seen several IP's that would NOT pump fuel anylonger... mostly due to water contamination, I'm sure, but used motor oil would wear them out MUCH faster...

please, all you wmo watf naysayers keep preaching. i would certainly hate to see my suppliers start charging me for this stuff.:)

I am not advocating using WMO. I am just saying there should not be any repercussionsby putting WMO in an almost full tank. However, there are forum members using WMO/diesel mix on a regular basis with no ill effect.

My thoughts exactly. The information is out there and many people have gone at length to describe what they are doing (burning) how they are treating/filtering it, and their long-term results. That said, I advocate if you want to try an alternative fuel, do so, but read up on it first!! For those who just want to dump crap in their tank and drive, well, I have no sorrow or pity for them if they run into trouble. They were the ones who were too lazy to try to do it correctly based on others experience. Either way, no one should be chastized for wanting to push the envelope a bit. They do so at their own risk. Besides, if no one tried anything new, we would still be riding horses and rubbing sticks together to make a fire.

Gee....a bit sensitive? You call it chastising, we prefer to call it educating.

After all he asked what would happen, and he got valid and accurate information. It WILL damage the IP. It WILL damage the Injectors, just try to find nozzels that aren't total crap today....you can't, quality ones are no longer manufactured. ALL the new ones are substandard to the Bosch German or French manufactered ones that are no longer made.

There ARE repercussions for doing the things you advocate.

Has anyone sucessfuly ran on WVO for 4-500K miles without harm yet? Nope, anyone do it on used engine or transmission oil? Nope.....and if you watch eBay long enough you will spot cars people did mess up doing this and now they are pawning off the results on unsuspecting individuals rather than living with it until it ends up scrapped. Sometimes praising the very systems most people know are really destructive. Always on the people that are least aware of what they are getting.

Nobody said it would kill it next week or tomorrow, but most of us look at a few years down the road, not if it blows up next week we wouldn't care.

That two gallons might have caused about a normal 50K miles worth of additional IP wear, and accelerated the wear of the injector nozzles over what Biodiesel or dino diesel would have resulted in. And the Ultra Low Sulfer Diesel is bad enough on its own.

And there are a lot of members that have seen issues, and had damage as a result. Plenty of threads that go back a lot of years.....I've read many of them myself.

The are wrong ays and better ways to do WVO....but the best way is to properly make and wash your own Biodiesel...it has the least long term ill effects.

Most of us look at getting several hundred thousand additional miles out of these.....and would not be happy doing someting that would accelerate its demise in any small way.

I call it scaremongering. If Dino diesel #2 is so good and last for 4-500K miles then there will be no junk cars in PNP.

"2 gallons might have caused about a normal 50K miles wear and tear" then 20 gallons would give it 500K wear, end of the line for the IP. Ask any members who run it regularly and I am sure they have put more than 20 gallons thru it.

Cars end up in a PNP for a number or reasons....many really shouldn't be there by all rights had they had owners like members of these sites.

500K isn't going to happen without some work most times....but an IP shouldn't be dead by then if it had uncontaminated fuel.

Are you able to produce any statistics to prove your claims? how many of them still are driving their cars years later....how many of them even got an extra 100K miles doing that?

I bet the ones that killed their cars refuse to accept responsibility for what they did.

But heck, its your car, you can run it into a tree if you want to. But that doesn't mean its good for the long term survivability of the car. Most of the people here don't consider their cars a hooptee they only ever expected to drive a few months and move on to the next jalopy.

And the advice we are giving IS accurate, and valid. And its NOT scaremongering.

I wouldn't because of the pollution aspect... I send my old oil to be recycled

I forgot I have a real example.

Back in 1989 I worked as a Generator Set Mechanic at a place that worked on Refrigerated Containers.

They had a Contract with Dole and at the time most of their Gen Sets to run the Refer Units were Carrier 3 Cyl Air Cooled Gen Sets.

Someone at Dole decided that they could add WVO to the Diesel Fuel.
(I have no idea if it was pre-filtered or the proportion of Diesel to Oil.)
The Engines were IDI Engines with a Squish type pre-chamber. The Injectors were Standyne type Pencil Injectors that had 3 holes at the Nozzle end.

The result of the WMO usage in this case was that that one or 2 of the Injector Holes would plug up with a white crusty solid material.
In short the cost of fixing the Injectors was erasing the Fuel savings cost of using WMO.

The above story is also somewhere in some of my past posts.
