This one is out there for everybody no matter what Country! please give a view and discuss?
I was involved in a demonstration today which involved draining the oil removing the filter and
rigging a machine which pumps a vegetable oil based with additives into the filter under pressure
cleaning out old combustion particles and any nasties out of the sump and back to the machine via a
filter, this does this through the cycle of around 4 times with an air clean at the end now they say
this improves running, better fuel consumption and probably enlightens you to a higher plane
according to the sales pitch, is there anybody out there that has heard of this process
and what are your views on such a process of say older engines

I always thought that mixing veg oil an mineral oil only gummed things up.
Why veg oil.why not use mineral oil with these addatives .
Hmmmmm
Wot about terraclean which cleans the injectors cats and exhaust system.this seems to be the latest thing
If if good enough for Ed China then it has to work.

I think it was a soya based cleaner, but the reviews from sceptical technicians he had in abundance he wants to do the z3 that's why I have put it out to you guys

I went on a tour of Mackie Automatic Transmissions the other week

One of the things they do is to hot oil flush the gearbox to remove particles down to 5 microns - this is a filter, you could feel the metal in the oil

You could do it yourself with engine flush, a special thinner oil, designed to clean the inside of engines. Did one of my cars with it, the engine seemed to be noisier afterwards because all the deposits that collect on the bearing surfaces had gone.

Probably the bearing surfaces gone more likely made it noisier. The oil viscosity is there to prevent wear on the engine, using a thinner oil or vegetable oil will only be to the detriment of the engine, just do more regular oil changes with the correct oil to get it clean and keep it clean, with the added piece of mind you are not ruining the engine.

I am sure you have seen the pictures of my internals, and this is just more regular oil changes.

Engine flush oils were widely used in the days when the only oil available was mineral oil. As you know mineral oils, unless changed very regularly have the tendency to sludge up and block the galleries. this is what engine flush oils were designed to combat. At the same time mineral oils left deposits on the bearing surfaces that were not removed by normal oil changes, Yes I agree in my case the engine proved to have worn bearing and piston rings and the flushing oil I used just showed up the wear in the engine. But that is what worries me about the process earlier described, it might highlight wear in the engine which was not recognisable before.

Would it not be adventagious to find out now that your rings and berrings were close to failing than waiting for them to fail because you thought all was okay inside.

I know Mike, I used them back in the day to my detriment, it was the engine builder then who advised not use them, including that stuff Slick 50 that used to be about. Since then I have just done more regular oil changes and never had a problem. But the truth is engines wear, you can slow it down but you can't stop it.

I totally agree with you: regular oil changes in our Zeds (and the use of a good synt oil) are the key to an extended life time of the engine.
Flushing , mixing remainings of engine oil with some other detergents or additives during the cleaning process, are not recommended.....and they bring just a sentimental value .....It's not like cleanning your teefs after meat!
