I am also friendly giant

I just remember it caused a bit of a bun fight on a couple of threads here and some other forums as well when I looked into it. The oil filter on a TD5 can work well enough to mask the oil losing its protective/lubricative properties, so the rule of thumb tends to fail in that particular case. For other vehicle engines (heavy/light/diesel/petrol) it might be a different story.

when I first purchased my Td5 2nd hand the oil was very black also spinner filter was not working


I bypassed my EGR and changed filters it still wasn't long before the spinner stopped working again and it did take a while for my engine oil was clean after many oil changes


now that I have my oil so clean I only change my spinner filter when I hear it not spinning when engine shuts down gets changed every 2nd service


I will agree rubbing the oil between fingers is only a visual check and not a full test but it is a good test and it gives a nice indication once you know your own vehicle


once you get to know your own vehicle engine oil is clean egr bypassed you can tell by the finger rub between services remember I have 30000 on the clock so I do expect to see some carbon in the oil as my piston rings are not exactly brand new
