Had the A6 TDi serviced last week, and thought I'd just ask what oil I'd need to top it up as and when.

Was happily told that its a VAG specific 5W40 fully synthetic for the PD engines, and that the indy in question can do a pretty good deal on it.

So whats so special about it? Do the VAG nutters put the essence of vestal virgins in it to keep the engine properly lubricated? Distilled essence of government lies to keep the cogs turning? Or is it just an exercise to see how much they can scam from the public?

This might be of interest to you:

Whats the VW spec that the handbook says your car needs. 505.01 or 505.06 that sort of thing. Then do a search on it and I'm sure you'll find plenty of different brands available.

Supposed to be specially formulated to cope with the high stresses at the top end of the PD engines.

Try paying for 507.00 - that's the DPF compatible stuff. £45 trade for 4 litres of it, and my Lancer needs 4.5 litres every 12.5k.

Should get a better trade supplier? £9.99 a litre retail for top ups.

Probably the same reason the car was expensive to start with - the badge on the front of it smile

Is it something to do with the sensor wires inside the engine that can corrode if the wrong oil is used?

In the USA, the Castrol SLX (made in Austria) oil for Touareg V10 diesels is (so far, and I'm looking) only available from VW dealers.
Our oil supplier, a Castrol distributor, can't supply.

I know of an under warranty, VW Passat with the 1.8T engine that had oil changes at a "fast lube" shop which had denied warranty for the engine failure after the oil was analyised by VW and deemed to be "incorrect" and a wrong type oil filter fitted. Cheap oil changes, $8000 engine repair.........

Check out the Shell Helix range of lubes too - I know the old man was flabergasted by the cost of oil from Audi, and a bit of research showed that the Shell lubes were marked with it... in fact, i think the top-up bottle they supplied in the boot was Shell Helix!

Probably a low-ash oil - using the wrong oil can bugger up the particle filter. You don't need to use their oil, just any oil that meets the spec, which will be printed on the bottle and in the manual.

VW can tell which oil is used as it contains a chemical "marker".

Didn't VW replace loads of 1.8T engines in the US due to sludge build up?

Really? I thought it was more than that. Quantum isn't VW oil anyway, it's supplied by VW but isn't actually the same stuff they fill the car with at the factory, or even the stuff a lot of the dealers actually use wink

The oil is expensive because it's 'longlife'. That means it stays in the car twice as long, but costs 5 times as much!

True, but virtually all synthetic oils, semi for fully, are low ash these days. Vauxhall use a 5W30 across virtually the whole range for cars on long life servicing, from 1.2 petrol engines to 2.0 turbo petrol engines and from piddly low blow 1.7 diesels to 1.3 CDTIs and 16v 1.9 CDTis. Even all Saab engines except high blow 'R' engines use it too. The oil is no different for cars with DPF filters where getting the DPF hot enough on a regular basis to burn off the crap if far more of an issue.

Modern engines with all their technology, filtration systems and high pressure, high strain injection systems simply need a more sophisticated oil to ensure longetivity of components. Engine technology has advanced massively in the last 5 years and tolerances are tighter than ever, so suitable higher spec oils are needed. Oils that cost more to produce to the finished product.

PDs use a very high pressure injection system and certain components do take alot of strain, heat and pressure. Premature wearing of camshafts on PD150 engines is common. Whether or not this can be attributed to use of incorrect spec oils is debatable especially when running on low oil levels, even for very short periods, or how it has been driven and indeed how often it has been serviced is probably for more likely to be the culprit IMO.

Personally I am a sceptic of long life servicing using advanced oils. I don't question that the oils are able to withstand up to 20k between services as they are in say modern Renaults, short term anyway, but personally I service all my cars every year and change the oil on a 6 month basis, even if this means 3000 miles in my case. Anyone who has seen the colour and thickness of oil that comes out of cars on long life servicing will know where I am coming from.

Oil is THE most critical factor in engine longetivity. I'd spend the money and stick with the exact specification of oil that the manufacturer stipulates on modern engines, both petrol and diesel. But that said, I run my 10 year old BMW on GM 5w30 with no issues, and the jalopy on GM 10w40, again with no issues.

You can get PD oil in Halfords for £27.99 for 4 (or 5) litres. I use it in my bora and have done for the past 3 oil services. not a problem.

To be fair, if you re-circulated your gin from your sump after it had traveled around and lubricated your system, I would be concerned.

I have a Audi A6 when using VAG long life oil how do you change the on board computer to take account of the extra mileage ?
I can only change it to the default setting 12k.

Any suggestions appreciated.
