Any of you monkeys have any opinions on flushing oils/concentrates? Thinking of running one of these products through the TD42 to help flush out sludge etc. Any brands or methods that are superior - please all positive info is good.
I know Penrite make a flushing oil - I've always used penrite in all my rigs.

Flushing oils/concentrates
Built, not bought.
God of Magnificant Ideas!
Dont know about positive but.................
I use the cheapest oil I can find (K Mart, Target, Supermarket brands) and a cheap filter aswell, do the change, chuck in the cheap stuff, run it for an hour and do another change to the premium oil & filter.
Same process is used for rebuilt motors on the first fire up except I use "motor honey" ( really thick shyte) on the new componets IE bearings, cam,crank,lifters etc ( applied by fingers) then add the cheap oil/filter , run it for 20 mins then dump the lot. Refill the oil and fit a new filter ( premium quality)..... done!
I only use "RYCO FILTERS" and "VALVOLINE OIL" as the premium
I've never had an engine failure due to bad oil or lubrication
problems yet and mine arent treated with care or respect !....
The floor is there to let ya know the carby cant open up any further!!!
ADD ON BIT...
an old bloke not far from my oldies hasn't bought oil for about 30 odd years. He has a 44 gallon drum in the shed and it has a tap 1/2 way up the drum. He takes the 8 odd lits he needs to do a change and puts that aside then does the oil change, the oil that was in the motor goes into the 44 and the 8 odd lits he took out then goes into the motor !!!!
As to how it works I dont know but he says 'The oil is fine its just "dirty". The time it spends in the 44 allows the "dirt" to fall to the bottom and the "good" oil stays up the top, I just take off the good stuff !'
I must admit when I saw the oil he took out for the service it was as clear as new stuff, felt the same, and smelt quite normal !!!, as to its lubrication properties.... thats anyones guess !!!
The car he drives is a diesel Merc and it runs as sweet as the day it came outa the factory....
go figure !

Perhaps he had 'magic oil'... Don't know how old the guy was, but perhaps he had better things to spend his pension on, and maybe he wasn't too worried about the motor needing a rebuild if he couldn't get himself rebuilt...
Most of the oils today are fortified with chemical components that tend to be sacrificial, and only have a certain lifespan in a combustion engine. The fluid carrier is nothing more than that, holding the chemical components in suspension to do their lubricating duties, and to hold the waste products of combustion and wear in this suspended fluid carrier. Once the chemicals have been consumed/depleted, and the concentrations of suspended contaminants (byproducts of combustion - both solid and chemical) reach high levels, the fluid carrier is next to useless.

Hey there area54
I have always run quality oil and toyota genuine filters on my truck but being the curious fellow that I am I saw an article on the COF additives in 4wd monthly and decided to give them a go. One was an engine oil flush the other an oil additive that supposedly helps with friction etc.
Well I followed the directions to a T and then put my new oil in with a dose of the anti friction stuff. To this day (I did it once a few months ago now) I think my oil pressure has never come back to where it once was. I noticed no difference at all and my oil still goes black in a short time.
I have about 250 000 on the motor but it is in top nick. (compression, oil pressure etc checked with my diesel mechanic and all well above average)
I would not bother myself but if you have the dosh give it a shot I guess it may work for you.
PS I rang the guy from COF and he was a waste of time 'oh that shouldnt happen....... was about it for words of wisdom)

I too have seen those products advertised - I'm dubious about friction modifiers (PTFE or similar based friction modifiers - STP, Nulon etc) - expecially in my diesels. I know about studies and road tests that have been done - I don't doubt their validity, just a personal preference.
Looking more at the products that will clean the motor out of sludge and semi solid combustion byproducts that won't dislodge with a normal oil change. I also use a high quality oil and RYCO filters, but I was surprised to see sludge in my motor. Perhaps a flush is normal for X number of oil changes - surely some mech monkeys can enlighten us?

Hey there
Don't know if I mentioned it properly but I used one of the flushing concentrates and I reckon it did sfa. It may of cleaned a bit of crud out but I also lost oil pressure????? Might be the pump shi/ itself?
The additive I used reckons it is not a friction modifier but I just couldn't think of anything else to call it.
I think maybe with any of these additives your motor has to be pretty shagged to notice a difference. IMO

chemical stuff
Was talking to the mechanic at work the other day about some of this stuff and he reckons that dont work. He related a story of when they used slick 50 in motors and that it was so fluid that it didnt stick to anything and caused problems to bearings etc.
And it was a bit like the good oils like 'Mobile 1'. If it wasnt used from day one there was no real benefit.
As for Oil flush he reckons it just moved the sludge from those little hidy holes and forced it into oil pumps and oil screens.
So still dont not sure about those oil flushes.

Maybe the oil pressure dropped due to improved oil flow through the galleries, due to less restriction, much the same way your blood pressure drops if you have clear unrestricted arteries, but that's another story...
Anyone have any more experience with flushing oils, or are they a waste of time - the only thing you'll be flushing is your money?
