Nooooo. Just do a couple of short oil changes. You can do more harm than good.

just out of curiosity how come mal cos your running the engine on contaminated oil and it can damage journals, or eat seals cos of the chemicals, i always liked to flush my engines to get the crap out of oil-ways and so forth admitted i'll usually get the sump off and rocker cover and do that lot by hand it's so depressing giving your car an oil change to find 50 miles down the road your oil looks dirty again

Dangerous Malcolm..

If you remove and clean your rocker cover and sump then fair enough. But sometimes the flush can dislodge otherwise harmless lumps of shite. As a case in point my uncle ran a flush through his rover diesel and within a few miles suffered camshaft failure due to oil starvation. On stripping down a lump of what can only be described as varnished oil residue had blocked the oil way. I've also read on t'internet pretty much the same.

ok sounds a very valid point , to be honest i'm sure iv heard that about but never bothered me because of the fact i'll usually clean valve-train and rocker cover and sump and pickup and wherever else i can get my grubby fingers into () at the same time i do a proper service on my cars

If your uncles car had been properly maintained using decent oil in the first place this would never have happened.
You cannot keep the oil clean FACT, you burn fuel which is fossil fuel you produce carbon, simple as that, some gets past piston rings and turns the oil black, higher compression on diesels means more blow by rings more carbon more black even quicker.
You can slow down the process by ridding the internals of all the varnish etc from the oil that has accumulated but never 100%.
I use WYNNS, it is very soft and leave it in for 200 miles before oil change, never a probe in 20+ years.
