Thread: food for thought - 5W-30 vis 5W-40 engine oil

Ok based on what has been produced I can accept that the D3 and D4 manuals indicate that it is sealed for life - however there is nothing about it in my Handbook and I have downloaded the genuine Landrover workshop manuals and Service Schedules form Topix for both the D3 and the RRS and they say this and nothing about sealed for life.

So it depends on where you go - some Handbooks say sealed for life, some don't but the genuine Workshop Manuals and the genuine service schedules all indicate a service interval.
Go figure .

have a BEX and do some research

chaps as the OP of this chestnut of a thread the topic 9is about the 2 engine oils, can we stick to topic and take the transmission fluid debate elsewhere
thanks

I'm looking at creating a video for my YouTube channel based on my oil sample results on this subject. Although I have the results of 16 previous oil samples for my D3, this is only 1 engine with a limited amount of different oils in use (only 3 different oils) If any of you have done any oil sampling on either the 2.7 or 3L engines and would like to contribute your data to the pool of information I will use I would greatly appreciate it. Extra data will help balance out the averages and give a better result for all, hopefully it can gain some meaningful data on the subject rather than just opinions that are floating around

Nah asking you - well what is the answer - you started this line of discussion.

I guess you dont know .

Some good digging on information here.

I'd always take the the manufacturer of the parts advice over the advice of the company that use the part as their vested interest is to make you think the car is cheaper to maintain than it really is.

Also, just a bit of common sense tells you nothing is built for life that needs lubrication, the oils will always breakdown over time. Again, on the avg's I saw ZF material said on Average change around every 100K's and then on a LR manual for 8 speed change every 40K for heavy use. So I'd be guessing for those not doing much towing or 4WD work to do closer to 100K and those that use this vehicle like a commercial vehicle should do every 40K.

Is that a good summary?

Castrol EDGE 0W-30 C2 is an advanced full synthetic engine oil suitable for use in automotive petrol and diesel engines where the manufacturer recomends an ACEA C2 0W-30 lubricant.
.

I'd value the thoughts of those wiser than I on the interesting fact that the PENRITE ENVIRO+ C2 0W-30 (FULL SYN.) product has the same specification as the CASTROL EDGE 0W-30 C2BEST oil recommended for 2014 D4s, i.e. ACEA C2 / STJLR.03.5007, and specifically mentions "Landrover Discovery 4" despite having a different Ford WSS-M2C950-A specification.

I suppose the definite reference should be the workshop manual, ie. 5W/30 – WSS–M2C913–B or C for ROW, indicating the previously identified PENRITE HPR 5 5W-40 (Full Synthetic) is the right choice.

It really shouldn't be this hard........

a) LR have indeed stated, both to the customer and to the workshop/dealer, that the ZF auto transmissions are filled for life, for both D3 and D4 models.

Except that the most up to date service requirement information shows that in the 120 month/260,000Km service that the fluid and filter is listed for replacement on the 8 speed auto.

As for engine oil, I’m going to continue using Castrol 5W-30 A5.
