D4 3.0L Oil & Filter Change

[LGM]

O.K.

I am about to change out the oil and filter for the first time on my 3.0L D4.
Yep, I do have the correct oil, oil filter O ring and filter!

Is there anything special I need to know? Is there any peculiar foibles that are awaiting me that could bring me undone?

Oh yes, after much searching I managed to find what I think is the oil filter housing hidden under the engine cover on top of the engine?.

What about the filter change? When I undo that cover does oil go everywhere? I also know that I will need to carefully measure the oil coming out and going in.

Curse you electric measure machine!

I even have a hand Vacuum pump to suck out the venom (bad oil) and a spare sump plug to do it the old way if that does not work.

As you can see I am prepared for most issues that I can think off. But I would rather have the benefit of your experience to assist me which no doubt will will be helpfull and illuminating.

Draining via the sump plug ensures that the sump will be empty.

Why not just measure the correct amount for a fill rather putting back what you removed? Following is service bulletin SSM49357 from Topix as reported by a Disco3.co.uk member:

Title: 3.0 TDV6 Engine Oil

Issue: Clarification on engine oil specification applicable to 3.0 TDV6 derivatives.

Cause: Incorrect engine oil specification being used in some Markets.



Action:

The engine oil used in 3.0 TDV6 must be to specification WSS-M2C934B (ACEA A5/B5/C1). Land Rover recommends Castrol Professional Powerflow C1 5W-30 especially for vehicles fitted with DPF (Diesel Particulate Filter) as this engine oil is specially formulated to minimize ash build up.

For non DPF vehicles ONLY, engine oil to specification WSS-MSC913B (ACEA A1/B1) may be used. Land Rover recommends Castrol SLX Professional C1 5W-30. It is permitted to use an alternative to Castrol as long as the specification stated above is met. The grade of oil used must be 5W-30, there can be no deviation from this viscosity. Failure to use a 5W-30 viscosity engine oil meeting the above stated specification will have a significant effect on the bearing shells which may cause irreparable damage to the engine.

NOTE - It is imperative that when the engine oil is drained from the sump during routine service work and replaced, the correct amount of engine oil is added to the engine as follows - 3.0 TDV6 Engine oil service fill with oil filter change 5.9 litres – Maximum. Therefore it is essential the correct amount of engine oil is measured prior to filling.

Failure to follow the above instruction will compromise the engine breather system, potentially resulting in oil pull-over and subsequent engine damage

Thanks Graeme,

Was hoping to have a crack at the suction arrangement doing the job from the top. If I can do it that way it will eventually save a lot of mucking around jacking the vehicle and dropping protection plates etc.

None the less as you have said draining and filling the tried and proven way is most likely the go.

I am sure I have the right oil as provided by our local Castrol supplier 'Edge Professional C1 5W-30'. I understand the name of the oil has changed slightly but all the other specs are exactly as per the book.

Do you know the answer to my question on the filter?

The filter housing does not retain oil so the filter just lifts out with only a few drips. At least some, if not all 2.7 filters need to be pulled off its centre spindle with some sort of tool but that's not the case with the 3.0.

In reading the recent thread on changing oil and oil filter, I just noticed the specification of oil of 5W30 that is recommended and the warning in the bulletin about the bearings.

Is 0W40 a better grade, and is 5W20 also acceptable, since the latter one was used in my recent service at a LR dealer$hip?

Thanks,
Edwin

If they used 5w20 I would be demanding they drain it and start again. 0w40 is better for cold starts as its a little thinner again, but thicker when it's warm. I would be sticking with 5w30.....with the exact specific to what's required...not all 5w30's are the same.

Theres is no doubt about it I am no oil expert!

Mind you if the dealer or mechanic servicing my D4 put oil in the engine that did not meet the manufacturers recommendation I would want it to see the LR bulletin that gives the O.K. for a spec change. Failing that I would want the oil changed at their cost.

In any case I would also be on to LR Australia questioning the change!

Would that make me the cutomer from hell?

Perhaps 5W20 was just a typo. One of my oil change invoices showed the wrong grade but that particular oil isn't available in the stated viscosity.

[eddomak]

I just checked with the dealer$hip and the fill in service manager had selected the wrong option. When I asked if there would be a price difference the regular service manager said that there would indeed be a difference of $100 or so, so he would regenerate the invoice credit me back the amount.

When I was shopping for oil for my 2.7 TDV6 I was shopping in Repco and Supercheap. I couldn't find the exact spec oil (available oil was actually higher spec) so looked at the application chart. The chart lists different brand oils and what is suitable. For the 2.7 it was all 5w30 but for the 3.0 TDV6 the basic spec was 5w40 for all oil brands.
