Tdi oil pressure - any ideas?

Hi all,

I've just fitted a 200Tdi motor into my 90, complete with Allisport
intercooler. The question I have is, while dring normally, ie 10 miles
of A roads, the oil pressure reads 45-50 psi. However on a v long run
30+ miles or when towing the oil pressure drops as low as 35psi. Now
as I write this the differnce seems negligable but it is very
disconcerting when you see the oil pressure edging downwards when
you've got 2 tonnes or weight on the back heading out for a days
trialling!
So, has anyone else got an oil pressure gauge in their 200 so I
can compare these values?
I suspect, if the gauge is accurate, that the oil may be wrong for
the engine, getting thinner and thinner and altering the pressure.
It's Granville 15W/40 and although I was assured it met the spec i;m
not so sure now, any ideas on that one?
Also does anyone think that the oil temp thermostat may be dodgy,
I only ask because I had my sticky fingers in there while I had the
engine out!
Any suggestions greatfully recieved

The oil takes a lot longer to reach temperature than the water. In
general terms (ie not 200Tdi specific) hat you are seeing looks normal
for the oil reaching temperature and pressure dropping slightly.

15W/40 sounds right - although I've never heard of Granville oil a quick
look at their site raises a few concerns. Their Bronze 15W/40 looks ok,
but their standard 15W/40 is only CE rated which has been an obsolete
spec since 1996 (and was introduced in the 1980's) and is *not* really
suitable for a 200Tdi.

Since, when I am not under or in the Landy, I spend my life developing
lubricant test equipment....

If you value the engine, use a mainstream lubricant producer's
product.(Esso, Shell, Mobil, Castrol etc. etc.) From the smaller guys,
in the UK, Morris Lubricants make excellent lubes, even specifically
"classic" car lubricants - to the original recipes, and traction engine
lubes too. Morris tend to be a bit hard to find outside the Midlands.

The ad-pack in cheaper oils runs out in weeks not months and you lose
the benefits of the extra clever chemistry that is in the better oils.

My personal preference is for Pennzoil lubricants - any comments of a
learned nature on the quality of their products?

I don't know for the UK, but the importer for NZ is visible from my
kitchen window (and all the motor factors sell it (even the Halfrauds
equivalent).

the disco V8 seems to be happy with Castrol GTX "for high mileage
engines"...

Thanks for that. Do you think that poor quality oil is to blame for
this "problem". Although the engine is of an unknown mileage is hasn't
used a drop of oil or water in 600 miles (60 of which heavy towing)and
goes like a good 'un. Because I have an intercooler kit fitted and the
boost is turned up I want to make sure that the oil is absolutely spot
on. I drop the oil and change the filter every 3000 anyway.

I used to run Castrol Turbomax but that got discontinued a little
while ago, i'm sure thats why my TD engine lasted so well.

The spec on this Granville oil is as follows:-

API CG-4, ACEA B3/E2/A3-98 mean anything to you?

The manual for the 200Tdi engine stipulates BLS22.0L.09 and CCMC PD1
which adds to the confusion.

If u can throw any light on the subject i would be very grateful.

I'll wait until the engines done 1000 miles and then drop it out and
put in something better, do Castrol do an equivalent??

The is a morris distributor near here so I might try them too.

Do i think then that the oil pressures can be considered acceptable?

Right, thaks for the help so far, must go and remove the empty oil
containers from the computer room before my other half comes home and
thinks i've lost it!!

Cheers

Dave

they're one of the suppliers still marketing a half-decent 20W50 for
non-silly money. Silkolene do a nice semi-synth 20W50, but it's not cheap.

it's good enough for the 200 TDi.

HBoL states, for the diesel discos:

5W30 - 15W40
ACEA B2:96, API CE or better. Your quoted specs are comfortably better.

If you can believe the specs - some manufacturers are a bit lax about
compliance with the specs, and also as noted elsewhere in this thread
some oils break down in very short order.

I have several customers with vehicles that develop a major oil
consumption problem about 2000km after a change if cheaper oil is used,
despite it meeting the exact same specifications as the oil I normally
use. I discovered this the hard way when the distributor substituted an
oil in my order without telling me - worse yet they delivered 250 litres
of it into my bulk tank. Final outcome - lots of apologies, the proper
oil delivered and a reasoanable amount of free stuff (caps, jackets,
synthetic oil).

Frankly I agree with EMB - warm oil is less viscous, and therefore drops
less pressure in the engine. This is a good thing. Your fuel economy is
going to be better. If you use a lube which passes the ACEA spec, its
good enough at the moment you put it in your engine. After that, it up
to the reputation of the manufacturer. Granville is not one of my
customers. Since we make equipment that is mandated for ACEA
specifications...go figure....

CCMC ceased to exist sometime ago - there was a big bust up with a
couple of manufacturers, so everyone else buggered off and set up a new
group.

Lubricants are incredibly political things, believe it or not !

We use a Castrol diesel specific in one of ours, I think its magnatec.

Do so, and if you get stuck they have a good technical support desk.

Yes. Watch them rise again as the weather gets colder.

Thanks all for you help. Feel a bit more happy about the condition of
my "new" engine now. I think the correct course of action for me now
is to firstly get in touch with the local supplier of Morris oils
which I trust and if that doesnt come to anything then I will go back
to using Castrol that have done me so well in the past. I believe that
although the Granville meets the spec I think with the extra work it
is doing with the intercooler and mods I think I shall get the best
quality oil I can afford!

Thanks again

Bit late replying but the Morris oil you need is Ring Free 15w40 for a
diesel. It might even be a multifleet suitable for petrol engines.
Check the can for API SG or higher.

Isn't Silkolene brand limited to bike oil these days. Most of their
oils have been rebranded to the parent company name of Fuchs. A superb
quality oil suitable for petrol and diesel use is Fuchs Titan *****
[damn, can't remember the name just now] 15w/40.
As an aside, Morris make oil in 'own brand' cans for many well known
manufacturers.

what are morris' specs for diesel?

I've been putting GTX-D in the 300 TDi recently, having decided that the
previous stuff, while in theory up to spec according to its label, wasn't
much good. and for the V8, the new dumbed-down "GTX for high-mileage
engines"... which is in fact I think what GTX was before the latest update.

The Fuchs is called Titan HPE and the latest formulation is rated API
CH4 and API SL for petrol engines. I would think Morris Ring Free
would be to a very similar specification.

For racing bikes probably. Did you have a BMW bike? Did it like it as
in 'it liked a wee dram'?
