Vw spec pd oil

[Afour]

Hi all
Just after a bit of clarification here with regards to which spec oil to use as a google search just seems to bring up debates and no definite answer.

Car is Audi a4 1.9 tdi pd 115 bhp 2007 On a 57 plate non DPF

Now I believe the original spec was 505.01 5w40 and has now been replaced with 504.00 or 507.00 but debates sugest you can only use 507.00 on models above 2009 and with DPF??

Does any one have a straight answer on whats the best spec to use for this vehicle please

Cheers
Nigel

Research told me that the oil of choice for the pd engine is 5w 40 fully synthetic to vw specs 505.01.
I have 2 pd engined vehicles in the family, a 2004 model and a 2006 model and use the 505.01 spec in both.
507 seems to be used either on longlife service schedules and newer non pd engines.

I always used 505.01 in my PDs

Hi thanks for the replies

The only reason for really starting this,is because at work we have a oil blender as a supplier,so I asked them for a quote on the 505.01 and the reply I got was that that spec is obsolete now and has been superseded by 504/507 which googled sort of led me into all the disputes regarding wot u can or can't use.

So wot are the oils out there today that meet the spec 505.01 are they 507.00 ???

Hmm VW specs guide from Opie's site. I'm not suggesting you use them at all. It's just that they have a fair bit of info available

http://www.opieoils.co.uk/c-742-vw-engine-oil.aspx

'tis an interesting tale indeed.

"The oils in this section meet the VW 505.01 specification. These oils are especially for "Pumpe-Düse" (unit injector or "PD" engines) running on fixed service intervals (15,000km / 12 months).

It is vitally important to use an oil meeting either this, the VW 506.01 specification or the VW 507.00 specification to avoid damaging the diesel pump in PD engines.

For PD engined cars with a DPF, use only an oil meeting the VW 507.00 specification."



Personally speaking, if you have the facility to do your own oil and filter changes then I'd do more changes at much lesser intervals, and none of this 10,000 miles twaddle.

I also refuse to believe 10k oil servicing is adequate.
I only have one diesel,a commercial with similar unbelievable recommended service intervals,it gets changed every 3 months regardless of use or mileage.
Just the way the old oil stains your hands from all the soot should convince you that these manufacturers service intervals are absurd and probably responsible for a lot of premature failures,chain tensioners,turbos etc.

I'd expect better from a major oil supplier.

There is of course no diesel pump in a PD engine apart from a small lift pump to draw the fuel from the tank. The injectors themselves combine high pressure pump and injection functions, hence "unit injectors"

The reason special oil is needed is to protect the camshaft lobes that are used to pressurise the injectors, and which encounter very high loadings. The result of incorrect oil use in a PD is severe camshaft wear. This will eventually stop the engine through the lobes grinding away to the point where the injectors don't pressurise properly and the engine won't run, that's if all the swarf and metal filings created by the process don't destroy something else first.
