Oil filtration

<< < (5/5)

Diesel oils are usually a detergent oil which means they are designed to clean the inside of the engine and pick up the carbon deposits and is why your oil goes black. To me this is exactly what it is meant to do. I had reservations about the toilet roll filter as I knew some truck drivers back in the 1970's that went over to them for cost saving but cost all of them engine rebuilds. They simply do not do the job as good as a proper paper element / cartridge type because of the type of paper used.
However one of these filters used on an engine that has not  usually have a filter of any kind is better than nothing so long as the full flow is there.
