Thread: Do I really not need to service my Puma for 20,000km?

I have free scheduled services for 3 years, but the service amount came to $617.90 in total, including GST. That included $91.80 for oil, $11.36 for a drain plug, $33.97 for an oil filter, $55 for consumables (which appeared to be filter disposal, liquid waste and environment levy charge, greases, oil absorption materials and "fluid top up"), $33.60 for a tyre rotation and $336 for the 20,000 km service.

My 2c, I always do 5k oil changes on my cars, but one time with me with a bad back and a couple of long distance shooting comps I did not realize I had clocked up 30,000km between changes!
Annoyed with myself I changed the oil and it was actually lumpy and so black it stained your hands with carbon. It was my Nissan which survived the incident maybe as it has two oil filters, but IMO if oil becomes lumpy custard in 30,000km 20,00km is also far far too long 10,000km max for a diesel.

We need one of the smiley face things that show a bloke smacking his head against a brick wall.You cannot compare indirect injection engines to a direct injection,unit injection or common rail injection engines.The TD42,2H,1HZ,3L,5L etc etc etc all need 5K changes because they carbon up like crazy,to the well know point of spinning bearings,don't put any Land Rover engine from the Tdi onwards in that class.Modern diesel engines are much cleaner burning than engines 20 years ago,you blokes need to stop thinking in the past.

As the manual says 20 k oil change unless used in arduous conditions then change at 10k if that is the case, arduous conditions are frequent start stop, idling /traffic and offroad use.
I think most people would come under the category of arduous conditions in some way.
Although I don't think the engines gonna suffer if you wait it out till 20k or LR would have specified that as the service intervals.

I reckon Lab testing is way overkill for a car motor, that's for medium and slow speed marine engines, I reckon the only test that would be worthwhile would be a viscosity race , that will tell you a lot if things and is very simple to do yourself.

That might be so, but even on the petrol new Quad bikes on the farm the oil goes thin and brown quickly, I find it hard to believe 20,000 is fine in a diesel, I dont care how clean it is, it is not going to be as clean as a petrol and I would not leave a petrol engine that long never mind a diesel except my stuff up...

I am not a mechanic & I'm not an expert.
However I have heard that modern oils going "brown" is what they are supposed to do, as they are keeping all the rubbish in the engine in suspension, so that when you change your oil, this rubbish will drain out, rather than being left in the engine?

I am sure modern diesel engines are cleaner, but I would be interested to see a sample of oil out of a Puma diesel after 20,000km.
Yes it is correct engine oil have additives to keep solids in suspension this is normal for oils used with a filter. It is a topic I have looked into quite a bit looking for hifi turntable oils and for the reason of the detergents motor oils were not suitable. Anyway I digress 20,000km is a long time and the oil filters will block quicker than you think when they do the relief spring lets the oil pass without passing through the filter. Dropping the oil is cheap as are filters engines are not, I cant see why anyone would not increase the service intervals. Also remember this is Australia not the UK. Engine get a much harder time in extreme heat, and it is a lot more dusty too. This should also be considered when thinking about service intervals.

We need to get away from ''this is Australia and we do it tough'' BS.An engine in the UK,Africa,middle east etc deals with just as much as they do here,during winter more in fact,also again don't compare a 4wd engine to something totally unrelated like one in a quad bike.Lastly oil manufactures,engine manufactures spend lots of time and money on their products,I think Penrite,Castrol,Fuchs etc know more about oil than we do,just use the recommended oil from whatever brand you prefer and change at 10,000km's,really this is not rocket science.
