Hi guys
i am going to do an oil change soon and i was wondering what your general thoughts were about cheap flushing oils just to run for a few minutes whilst sitting still and also your views on those ingredients that you can add to the oil just before a change such as wyns etc, its the 2.5td thanks

[Welung666]

DON'T DO IT! Oil flushes strip away a lot of the protection the engine has built up, best way is to stick to the short oil changes the TD's need. I do an oil and filter change every 3k max! No need to add snake oil

[MickAP]

I just try and leave mine as long as possible to drain out when doing an oil change.
It changes back to black horrid shitey stuff soon after you've changed it anyway on the TD.

my take on flushing oils

good for the bottom end / cr*p for the top end ( the cr*p can bung up the small oilways ) 

once it is in the engine, it could take a couple of changes too remove ALL the stuff and you don't want any of the detergent in there after a oil change 

if the engine has been abused ( oil wise )   best too put it on 1000 mile oil changes for a while and give it some nice long, steady runs ( too get the oil hot ) 

if its rattleing at the top, a bottle off wyns valve / lifter treatment at the same time as the oil changes will help

Hmm slightly different opinion here!!
no 1 its a turbo diesel!!
which has oil squirters in the crank to cool the pistons, these block up if oil changes are neglected!! so do it!!use a good quality flush additive such as forte or similar,this is simply added to the existing oil and you just run for 30 mins or so, then drain replac filter and refill,i use a trade only flush, which is damn good and it sorted out the boys overheating probs but it was too late to save the headgasket!!personally i flush mine whenever i think t needs doing!!

all good comments guys keep them coming, ive got the log book and it looks like shes been very well cared for with lots of oil changes etc, my question is this, is there anyway of telling if the engine is clean inside, it looks nice and clean under the cap but of course i cant see much, its my first diesel and i was kinda annoyed that the oil went black immediately after it changed it last time,

At the end of the day it's your choice.

My present TD has been very well cared-for all it's life.
It gets an engine oil/filter-change every 2500 miles religiously, using only GM 10/40 oil, which does the biz!
 
Charge-air pipe and EGR valve gets cleaned at the same time too.

if it was a petrol i would say defo no, and just do quick (500 mile) changes with GM 10/40, but i would be tempted to do it with the TD, as oil health is so critical on them.

[Ghost]

Dont know about diesel engine but for my cars I do an oil and filter change and use 10w50 oil drive 300 / 400 miles and then another oil and filter change and use 10w40.
I,ve never had any problems and it gets the insides nice and clean.

Seems kinda 50/50 to me as to whether to do it or not, would like some more tractor owners to comment on their experiences, suppose a few will turn up soon, they are slower then the petrol models after all

lolol yep but they go further on the same amount of fuel,

[mantahatch]

A friend of mine rides a trials bike. He has been advised by other trials riders to drain the oil from his bike, then fill with the correct amount of DIESEL fuel run for a few minutes making sure not to rev/load the engine.

When he told me about this I was very sceptical.

Oh yes engine has to be hot through out the operation

What do think ?

[MickAP]

Mine will be getting an oil change in the next few days.
I will give Omegatoys method a try.
That's add an oil flush to the existing oil, run then drain.
Forte's recommended?

Used it meself on the previous tractor Mick.
Personally, I'm just sticking with the regular 2.5k oil-change regime.
 

[Old Fella]

Personally I add STP engine flush to a hot engine & run for fifteen minutes before draining oil. I do this every 4k miles. Car has covered 160k miles now & engine sounds fine - touch wood!
