What TDV6/SDV6 engine oil are you using?

[kelvo]

As the title says, with my Td5 it’s any easy choice of Penrite HPR Diesel 5, but what is the ‘best’ oil for the TDV6/SDV6 engines?

Penrite list three oils for the TDV6/SDV6 and Castrol say you need to all their tech department, which I haven’t done yet

More specifically for my MY14 TDV6 (No DPF).

Thanks

Follow the Ford specification to be sure you are using the right oil. If you have a DPF then their Enviro C4 5W-30 product is perfect. If no DPF then the fully synthetic 5W-30 suits.

No DPF product.

My indie recommended a 40 weight and apparently they use a Motul product in all the TD/SD engines.

I'm using the Enviro+ 5w40. Hangover from when it had the DPF and I've just stuck with it. It seems to sit somewhere between a thick 30 and thin 40.

Crazy idea but why not use the oil spec specified in the owners manual?

[Grappler]

Ive been using this for in TDV6 2.7 and Puma 2.2. Both without DPF.
As well as FORD WSS-M2C-913C approval it has Jaguar/Land Rover STJLR.03.5003 approval

Total Quartz 9000 Future NFC 5W 30
QUARTZ 9000 FUTURE NFC 5W-30

I don’t risk using anything other than the spec as defined by LR given the propensity for crank failures in these engines. This may mean I’m actually adding more risk, but I’ll stick with the 30 weight and change it more often. I’m now down to 10k services versus the factory 24k which the previous owner followed.

I use Valvoline Synpower FE Full Synthetic Engine Oil 5W-30.

It's what my indie used before I started doing the services myself.

I do 10k or 12 months unless I've been towing hard, in which case it's 6 months. I haven't hit the 12 month limit yet and if it's getting within the projected trip distance I'll do it before I go. I don't think I'll ever be comfortable with extending oil change intervals > 10k in a Diesel.

I had a look at the specs when I did my original search and the HTHS is so close between the specified Xw30 Castrol and the 5w40 Penrite that there is nothing in it.
My problem was when I originally looked for a viable oil I still had the DPF, and the Penrite was actually the best available fit in a full synthetic. Now I'm DPF free I could potentially change it up, but the Penrite also suits my other vehicles so I'll stick with it.

Not crazy at all. I know my engine (MY14 TDV6) needs to be 5W/30 and meet specifications WSS-M2C913-B or C. But as the saying goes ‘Oils ain’t oils’.

Maybe I should have asked “What 5W/30 engine oil, that meets specifications WSS-M2C913-B or C, are you using in your MY13 onwards TDV6/SDV6 engined Discovery”

[DiscoJeffster]

Let’s be honest, no one here can confidently and empirically say any oil is better than another other than those testing their oil, and even that isn’t a true comparison as there’s no baseline data. They can say though that their choice of oil is at least not bad. At the end of the day, if you stick to brands that meet the requested specification you’re pretty likely to end up with an oil with the correct additive pack included as the engineers designed it for. If you then change it more regularly then you’re likely to be a happy camper. Anyone who tells me Mobil this, Castrol that are generally falling for marketing.

TBH I’d use any oil that meets the Ford specification that is best value at the time I need it. Maybe I’m a simple man these days?
