Thread: how often is too often (servicing) - some questions

Fixed servicing plans often include both distance and time numbers.

Sorry I should re-phrase that - presumed costs - tell someone they only have to service every 12,000 or 24,000kms they think that's about 12 months or even more . Tell someone they have to service every 250 hours they straight away think Wow that's only 11 days. - so they assume they will be doing very short service intervals as they relate to time not KM's

Not a good marketing look for car companies

Hmm, yes, I neglected to allow for the stupidity of the general population. Fair enough. :-)

Still, from an enthusiast perspective, my point stands - do these cars have an engine hour meter in them anywhere? Could actually make for an interesting additional metric when looking to purchase second hand?

I assume harder-worked engines are more likely to get hotter than normal and accelerate oil breakdown. Is that right?

My understanding of these cars is that the cooling system is somewhat over engineered, so the engine temps are pretty well under control. If the temp still gets too hot the computer starts to take drastic measures like disabling cabin cooling, reducing engine performance, etc.

I've just brought a vac pump and will be doing the D4s first oil/filter change soon at around 11K plus a fuel filter change. Should make a change from the oil up my arms and/or over the floor of my previous Landies.

So why did the Service interval double from D3 to D4? Doubt a big jump in oil tech. More likely the Toyo v LR service cost discrepancy?

Absolutely, the harder you work it the more heat you dump into not only the cooling system but also the engine oil. With my camper in tow I can get upto an additional 20deg temp in the engine oil at times over the standard unloaded temps. The disco (mine at least) is a fairly hot running engine IMHO - which I suppose is to be expected somewhat with a small capacity engine pumping out as much grunt as they do

I would imagine that advertising a vehicle that only needs to be serviced once a year or every 24,000ks makes it a Good selling point
