Oil Question Again

Thanks Shane (for answering the Dorothy Dixer with real data).

Probably very important to point out that you would probably do a lot more long distance driving plus you live in a much warmer climate than someone that lives in the major cities in the southern parts of Australia.

So your results may not be replicated for someone that is based in a cold climate and does a lot of short distance trips.

Very interesting Shane!

How do the ACEA E oils eg E9 spec with extended drain intervals such as Penrite Diesel Enviro+ range compare with the A type? Push the drain intervals out even more?

Viscosity no issues at all, there was one sample with a small increase in fuel (2% vs 1%) but not worth worrying about - anything >5% is where I draw the line for fuel. Total base numbers where a little lower but that is to be expected as the additivities are neutralizing acids over time - still plenty in reserve so again no issues. Soot levels are fairly stable all round.
I mainly pushed the big oil changes as a test to see how the oil would hold up, especially considering the 24,000km service intervals on the 3L. Overall, I generally have no issues with the oil condition with the longer change intervals.

just looked at the castrol site for the tdv6 and tdci 2.7l v6 is Castrol Magnatec Stop-Start 5W-30 Engine Oil

and none of the edge range came up as suitable...

hmmmm

It is an interesting pick up Inc. From what I can tell - Castrol are not saying the other oils are not suitable, they are only showing what they recommend and want you to buy.

Pretty sure LRA was exclusively using Castrol Edge Professional back when they were selling the D3/D4’s and they still recommend Edge Professional today.

Looks like Magnatec meets the specs but I note the viscosity is at the thinner end of the SAE30 range compared to Edge or Professional in the same grade.

Not sure why the Castrol site is not offering up the same oil LRA were using as an alternative given they have an exclusive contract with LR to supply oil.

Edit: full disclosure - I don’t use Castrol - but if I was going to stick with the LR recommended oil grade, then I would look to use the Edge or Professional range. I would steer away from oils which are closer to being a substitute for 5W-20.

Actually, the results prior to the end of 2018 was when I was living in Tom Price. There was an awful amount of short trips there running around town, mixed in with longer distance runs. Generally each year I've been up around 30,000km travelled

No idea as I have no data on that spec or on the Penrite Enviro.

The reasons for the failure of the crankshaft and mitigations (aside from the unproven thickening of oil). So dont buy a car with crankshaft built on Monday(haha), dont unduly load crankshaft at low revs with potential for low oil flow and dont remap TDV6 to SDV6 spec!

Yeah… Nah!!! [emoji23]

I’m happy to play that lottery!

By that logic, buying an SDV6 and de-mapping to TDV6 would improve your reliability…

I don’t buy it. No way would LR build an otherwise identical engine, but swap in a weaker crank for the tdv6
