And just to add the new diesels don't have that problem anymore ya can run them normally around town and it regens anyway.

What's the craic with these long life services on the daysels, Joe Duffy did the last service on my yoke an he reckons the long life service interval is 30k. I wouldn't trust it meself. Hard to believe the oil would stay healthy for that long.

[Rat Catcher]

On VAG cars the variable service interval has been around for a long time. 30,000 kilos is the maximum for diesels with DPFs but the display will tell you when it wants the oil changed, I think it gives you a countdown starting at 1,500 kilos or something like that...provided it is set using the OBD interface, if it's set using the clock controls it'll revert to fixed service interval i.e. 15,000 kilos.

[weird al wankovitch]

The last 5k the display gives a warning for a service when the car starts. The yoke was serviced when I bought it and the next service on the screen was in 15k which must've been regular oil. Last service they asked did I want a long life service for 20 quid extra which by their reckoning is 30k but I wouldn't trust it so I think I'll leave it back in for a service at 20k just to be on the safe side.

The so-called long life oil is specified for both fixed service and variable service intervals on DPF models as far as VAG cars are concerned.

But did you pay the extra 20 squid to drive 10k less?

[weird al wankovitch]

No, 5k more. I don't know, Hal. I'm wary of these long life scams. Why are there 2 different options. If one is better than the other it should be standard to service all cars with the better one don't ya think?

[Shallowhal]

Absolutely.....don't know why they even offer a "lower" grade oil....Foreskin Sprung Technique should be their motto!!

Go with manufacture recommendations as specified in your handbook. They are best placed to know what they're talking about. VAG cars that are designated variable service intervals are supposed to be clever enough to know when they need an oil change, subject to the 30/50k limits.

My own approach is probably best on balance - use the so called long life oil and change it at 20,000 kilos unless the car asks for it sooner - very unlikely. However, there are probably trade offs in using the long life oil - although, last time I checked the same oil was specified for VAG diesels with DPFs on fixed service intervals - i.e. the thinner consistency provides less protection for cold starts and such like. That seems to broadly concur with the following advice from Volkswagen:

https://www.volkswagen.co.uk/owners/servicing/regimes

As a Volkswagen owner, you will already have experienced the pleasure of driving a car that's renowned for reliability. So when it comes to servicing it, why settle for second best? Visit your local Volkswagen Retailer or authorised repairer who will be ready to help you every step of the way. Their staff are fully trained in every aspect of servicing to ensure you continue to enjoy mile after mile of trouble-free driving.

You can choose from two types of service regimes, depending on your driving methods.

Fixed Service (Time and Distance)

We recommend this service if you are likely to drive less than 10,000* miles in a year, and if you tend to drive in the following way:

Mainly city centre driving, short journeys with frequent cold starts
High engine loading activities, e.g. frequent hill climbs, driving with your vehicle fully loaded and towing
Uneconomical driving using high rpms with heavy acceleration and heavy braking.


Flexible Service Regime (LongLife Service)

We recommend this service if you are likely to drive more than 25 miles a day, and if you tend to drive in the following way:

Regular long distance driving
Driving at a constant speed with minimum vehicle and engine loading, and minimal towing
Economical driving
This Flexible regime has been made possible due to the development of new Volkswagen engines with the latest technically advanced longlife oil. These engines use built-in sensors that continually monitor the oil quality, making it possible to enjoy reliable and confident motoring for up to a maximum of 18,000* miles or 24 months (whichever occurs first).

*Please note that all mileages are approximate as the service indicator system uses kilometres as the distance measurement.

Yes rats it a Skoda Import, a 1.9 greenline which unfortunately for me means they added the doc in as an after thought to the PD engine. I don’t know if it’s fixed or variable but as its high mileage I do it every 9k miles and use 5w30.

C5, my car doesnt tell me it’s nearly full. The light comes on and that means it needs a good run in 4th gear at 2000 revs up the M1.  I had been doing this any time the light came on but this time due to this underlying issue the light never came on to warn me.

It’s gone from my car now and i might not have to get it NCT’d again so IDGAF

does your car go in to limp mode when you get the dpf light on.
on the avensis the car power downs, you get a check parking brake warning, a traction control warning, a check engine light and a few others.

Some mechanics would argue that you are suffering the disadvantages of the thinner oil (less protection on cold starts, more camshaft wear, etc) without necessarily reaping the rewards (longer service intervals). The identification sticker will give the manufacturers specified service regime. As far as I recall QG1 is variable and QG0 or QG2 are fixed. Variable can be changed to fixed but fixed shouldn't be changed to variable.

I wouldn't be surprised if Al's flute goes into limp mode with the yokes i've seen him transporting around in his VAG!!
