Cheers

yup, have tried it as a bloke sent me some free lol

bloke on Exploroz sells the shit (the supplier), and one bloke tried it on his old donk, and amazing amounts of poo came out with the oil when he changed it.
Mine did too. Going to do it again before selling the GQ.. Oil comes up much cleaner for longer.

Does it do anything for economy, etc nope, and dont see how it could deglaze, a long run up the freeway does that free.

i threw in 2 bottles of nulons engine flush before dumping the oil at the last change. thins out the oil heaps so hopefully it got rid of some of the crap in there.

why not rip the sump off and clean it out ?

cheers

avtur,(jet fuel) is great for cleaning out injectors...

engine oil flushes, tend to work on petrol and gas engines but in diesels where carbon is at the exteam its debatable.

engine oil additives, just think if 50ml of oil additive to 5L of oil does such a great job at increasing an oils lubricating effectivness, with a worth of probably around 5c. you would think all oil companies would add it to their product to gain an edge. the fact that they dont says alot more to me than a sales rep feeding me a load of marketing

petrol injector cleaner is just a mix of diesel and kero, it doesnt do much for your injectors but it may clean a bit of carbon off the intake. to clean injectors they need to soaked in a sonic bath back flushed and parts replaced if req.

just a quick run through of such products as i understand them

I used that product when I first bought the Patrol, I'd just done an oil change as par-for-the-course when buying a second hand car, but did another one anyway, just to try the product out, and see if it helped with the heating problems that one of their users had solved.
The crud it brought out in the oil was phenomenal, and had to have done some good no matter what else it did. So I ran it again a second time but with much lesser result. So one application appears to be sufficient for a while at least.
However, I've since heard you can accomplish the same result just by chucking some diesel fuel into your oil, running the car a few seconds, and then doing the oil change. Not sure I like the idea of fuel in my oil, but it would certainly be a cheaper option than the product was.
I was happy with it, and still have quite a bit of it for use again in a little while, probably put it in the day before my next oil change. One bottle will do a lot of treatments from memory.

I was looking at doing this to mine, but a mate had problems where it cleaned too much sludge out.
Turns out the skudge build up was hiding the fact he needed new rings, so once the sludge was gone, he started having blow by problems

Still debating whether or not to try it myself.

thats exactly what im thinking... similar example different circumstance, i used to have an old ford xe, i had to change some bushes and shocks for a RWC, but when i done it the car started to have what felt like a bump steer, i could only put it down to that the whole suspension and bushes was worn out but all still ran well together, one new part stuffed its moulding...

If ring land carbon buildup is all thats stoping the blowby then after a flush (if it does actually clean enough)the engine will drive back to a better condition than before with an increased service life as well (then fill with a decent oil).

If the carbon has gone unmoved for long enough to cause a real mechanical problem then it was ready for a rebuild anyway.

I use the diesel power fuel additive as it contains the same chemical detergent as ones added to some new engine oils. Does a good job, I also do not drive the car with it added because when these flushes flush a very dirty engine it works to clean all oil gallerys, virtually all of these gallerys lead directly to bearings and after the oil filter also, so the bearings need to deal with a greatly increased count and possibly size of contaminate before the this oil reaches the sump and is picked up by the pump and some contaminates are captured by the oil filter for the first time. Remember the reason why there is contaminates in the gallerys is because they were small enough to pass straight through the oil filter almost forever or until each just became unlucky.

Anyway each to their own but for me it is usually best not to torque an engine (no driving) while flushing as that allows the softest path through a bearing possible, but make sure it is done at a fast idle.
