Thread: TD5 Oil recommendations

Carlos, with that level of suplhur and without oil testing it would be anyone's guess.
The centrifuge filter on the TD5 is a brilliant bit of gear, but 1000ppm is a lot of soot going into the oil.
At a wild arse guess I wouldn't exceed 10,000km, (Land Rover's original recommendation was not to exceed 10,000km if sulphur levels exceeded 1%) and probably limit it to 8,000km just to be safe, but the centrifuge filter may be able to keep the bulk of the soot out of the oil.

The only way to know for sure how far you can go is to use oil testing with proper interpretation.
If you want to go that path I can PM the name of a very good analyst in the US.

With a mineral oil or semi syth. oil,I would be replacing the engine oil every 5,000km

A 10W-40 will be fine. Any links to that oil at all ?
You want it to at least have an API CF or ACEA B3 diesel rating, but as I've often stated, I prefer CI-4 to CJ-4 and ACEA E4 to 7 diesel oil specs in diesels, unless a manufacturer has a specific specification they call for.

Now this will cause a $#!* fight.

Regarding different viscosities, if it never gets below 10*C you can easily use a 15W-40 heavy duty diesel oil if it has a relatively high viscosity index.
Most all 15W-40's are thinner at 10*C than any 5W-40 is going to be at -10*C, and -10* isn't that cold for a 5W oil.
The TD5 doesn't use hydraulically activated injectors so it isn't that viscosity sensitive anyway, and I know of certain 15W-40 oils that are thinner at around 0*C than some 5 and 10W-40's.

The 'W' ratings refer to an oils pumping pressure at certain temperatures well below 0*, they often aren't a good indicator at how an oil behaves from around 0* and above.
While lubricating oils behave in a Newtonian fashion, (ie, the warmer they become, the thinner they become) the viscosity changes with temperature aren't always in a linear fashion either.

OK, sorry to bring up another oil question, but I am trying to find a decent oil for my TD5 here in Dubai. Previously I had been running 10w40 Mobil 1 oil for petrol engines, it also lists it as OK for use in diesel engines. The oil maybe a different spec to what is available in Australia.

There is a limited range of specific diesel oils available here, most people just stock straight 50w oils. Our temp here never gets below 15c, so low temp use is never a problem. So far the best dedicated diesel oil I can find here is Volvo VDS-3 15w40. http://www.volvo.com/nr/rdonlyres/91...294_200803.pdf

It is a SAE 15W-40 VDS-3, ECEA E7, API CI-4 spec oil.

We have high sulpher diesel oil here so I run reduced interval oil changes.

The way I see it Volvo won't recommend a crap oil for the trucks so it must be a decent spec. So it is probably the best way to go.

My question here is should I run this Volvo 15w40 oil or a high performance 10w40 petrol oil which is readily available.

Even in your temps I think 15W may be a bit heavy. I would be looking for a 10w I think. Currently I am in Newman which is a hot area and still running 5W with no issues.

You'll be fine but I'd like to see some Visc @40 & 100*C and/or it's VI just to see what sort of viscosity you'll have at start up, but at guess it'll be no worse than a 0/5W-40@0*C.
I did some numbers on here a few years back and Redline's 15W-40 (ok, its a POE syn diesel oil) was thinner at 0* than a Shell 10W-40 and IIRC roughly the same as Penrite's then 5W-40.

A CI-4 diesel oil can cope with the high sulphur fuel better than a petrol biased CF oil with better protection. (the CI-4 spec was developed about eight or so years back while the US still used 500PPM sulphur and the CF spec was superseded something like twenty years ago)

Any idea who's blending Volvo's oils for your market ?

What's the sulphur level there Col ?

nahh if your using a really good oil as the td5 has a centrifuge filter you can goto at least 10K Km and I used to service at the 15K Km mark. the oil testing that I did still had life in it at the 15K Km mark That was based on the nulon synthetic.

I believe I was originally told Castrol syntrans and syntrax oil for the transfer and gearbox, the order I am not sure on. Don't have my manual here with me. They are very expensive.
I change all gearbox and diff oils annually or 20,000km. Also change the coolant at the same time, use red coolant.
I use caltex fully synthetic in the engine and change it every 10,000km and both engine oil filters at the same time.

Any good gear oil should be fine in the diffs.

Dave, I think that 5,000km advice was in response to Carlos' asking about a distance re the dirty 1000PPM sulphur fuel he has to use in Sth America.

Oh, and it was all over six months ago too.
