Nothing is cheap cheap now days even me tea bags looking at a replacement motor 6 grand plus, if the blocks usable is the key can (not always) be re-built for a fraction I have a 2.7 that broke the crank with no damage to the block so you can be lucky I think he said it broke on start up or stopped so he may get lucky when you buy a used motor you still don't really know its history or what you might find inside so i prefer to re-build but to me is a hobby and I only charge myself tea and biscuits
Just looked at this from the Citreon C6 manual ref the oil spec , including the note at the bottom of the page ,
(*) In the winter season, on HDi engines, it is recommended to use 5W40 oil instead of 10W40 oil, this to enhance starting from cold.
(**) Do not use 5W30 oil on HDi engines with particle filter (FAP).

D4 will have a dpf, so will need a C class oil, C is for cat or in this case DPF.
Again think D4 is 5/30 and certainly not 10/40.
You sure that oil chart is for a disco, or some random french car hence the hdi designation?
sorry mate I’ve just made it a bit clearer as it’s from a Citreon C6 , just found it interesting
thks again as always

This guy (on another video) came up with the idea that Land rover td6 only has a oil spec of 5/30 as land rover asked if it could be run on that and not what would be the best oil for that engine; it would be good to get him on here, but he is upset by what people say on face book so do not think he would last long on here

It's all about emissions and mpg, not what's best for the engine. That's exactly why they say 5w30 for the rover v8

this is what this guy was saying, for most engines I would think would not make much difference but for a engine with a weak point maybe it doesIt's all about emissions and mpg, not what's best for the engine. That's exactly why they say 5w30 for the rover v8

Older engines have larger bore oilways and larger tolerances, aggregated by age and wear, so they need thicker oils

I should think he is probably right about that, although I know nothing about td6.
Modern manufacturers want the best fuel economy figures they can get to use in their marketing.
And thinner oil uses less energy to stir up and pump around the engine. so uses less fuel.

Less viscosity, less friction between moving parts

The problem is you spend best part of 100k on a new land rover and the first thing you do is drain the oil and replace it with something that will void you guarantee?

I don't have 100k to spend on anything so not a problem for me

Not 100% about that, the moving parts shouldn't actually touch when moving, they are floating on a thin film of the pressurised oil.
Not saying you are wrong, just that I don't know.
What I do know is that actually pumping the oil around the engine takes a surprising amount of energy.
Last year, I changed the oil in the Series from 10/40 to 20/50, partly because of the very hot weather last year, but also because I got a good deal on the 20/50.
During a recent cold start on a bitterly cold day, I was surprised by how sluggish cranking speed has become.
I know it is the oil, because once the engine is up to temperature, it spins over at normal speed if you switch off and restart.
I think it is quite simple, modern engines are built to such fine tolerances they can use thinner and thinner oils, think some of the small fords use 0w20 oil, and they wont be the only ones.
Modern oils are an art form, and engines can be very specific on what they require, this alone would put me off going thicker on the tdv6.
Just take a look at the ACEA specs and the C class alone has 5 very similar sounding oils but different nevertheless, and they are different for a reason.
This will send you to sleep!
C: Catalyst compatibility oils

Does that mean that there are some engines that are designed to be incapable?
And what should I use if I have one of those?

You're right, imagine it this way.. pour some water on the kitchen worktop, them slide a glass across it.. then do the same with treacle.
Ok, bad example as neither are good lubricants, but you get the idea, in the same engine where only the oil is different

Well paint it green and stick it in a boat of course
Talking about engines and tight tolerances I once heard that F1 engines are virtually seized when cold and won’t turn over until the oil and block is warmed up to then allow them to start due to the extreme tolerances
of course that may be total bull and with me not having that kind of knowledge that many of u have its well above my pay grade
plus might as well throw in another daft question so only get bits thrown at me once, lol
We’re glow plugs also part to reduce emissions plse
right, am now going to take cover , lmao
