Diesel Filtration - Donaldson Filtration Solutions/Lake Speed Jr YouTube Video

[rstcso]

Everybody's favorite Motor Oil Geek visits Donaldson Filtration Solutions to discuss modern diesel fuels vs minimum government specs, and what Donaldson is doing to help prevent injector and fuel pump failures due to insufficient filtration. It's not Lake talking the whole time, either.

Really revealing to hear how much it damages fuel systems. We need Top Tier diesel more available to start with.

I went to Top Tier's diesel station finder and the only US station listed is Costco with the caveat "USA - select locations only". That's disappointing if you use diesel.

Any diesel in the US seems to be dirty. I have posted many filters from my truck which were all black with dirt at 15k miles.

Interesting that right at the end of the video he said that it's important that the fuel filter is changed out on the recommended basis. Not to soon and not to late. I wonder if he is thinking that a slightly loaded fuel filter has better efficiency than a new filter.

I guess I am guilty of too frequent filter changes in my baby Duramax.

I had the same thought. I've read/heard that some oil filters become more efficient as they collect particles... until the flow becomes too restrictive and you lose all efficiency, perhaps even going into bypass. This is why some manufacturers recommend changing the oil filter every other oil change. The Pilot's owner's manual doesn't give any mileage recommendations, only saying to follow the maintenance minder. "A" is oil change only while "B" is oil and filter.

More reason to stick with gas in lighter duty applications

Have to wonder why the fuel is so dirty in the first place. Gasoline doesn't seem to have this issue.

For work we do a lot fuel oil service around here. Furnaces, oil tanks etc. Fuel oil is just dyed diesel fuel. The amount of sludge and dirt that build up in the tanks and ends up in the filters after decades of use is something to see. It so bad at times that it will block the fuel lines.

Every fuel filter I removed from that Peterbilt I had or my f250 was always clean. Same with the ones I replaced at the construction company I worked at. As long as guys didn't get fuel from the tank in the yard we didn't see dirty filters.

Asphaltenes that are present in diesel fuel, agglomerate when subjected to heat and pressure in common rail diesel engines. The fuel return carries these asphaltenes back to the tank where they are filtered out on the next pass. This can be reduced by keeping the fuel tank filled thus reducing the heat buildup in the fuel. I change fuel filters every 14-15k miles and have never drained any water out of them on my 6.7 Cummins. The rear filter is usually pretty dirty but the front one stays clean.
Also, Biodiesel is a very aggressive cleaner that will clean any buildup in the system. If running it intermittently, the filter change interval is reduced.
