Difference in engine oil- fixed service or long life

[Freedomfighter]

After speaking to the service chap at audi, he said they use a different oil depending on wether your on a yearly service (or 10k miles) plan or the long life service 2 years or (20k miles) plan. He said the shorter plan oil was better for the cars engine as it was more thicker. Could anyone elaborate on this or know if it's true? Also how does that work when you buy top up oil from them or halfords etc. I have got a bottle of castrol edge in the boot which they gave me last year but I've changed onto the yearly plan so was wondering what this thicker oil was?

Longlife oil is fully synthetic 5w30 and has to meet VW504.00/507.00

Non longlife is semi-synthetic 5w40 and meets the older spec. VW502.00

In my eyes the longlife oil is of a higher quality and can last up to 19k miles therefore is likely to be in better shape after 10k miles than an oil that is only recommended for 10k miles.

For me it's longlife oil but change.every.10k / 12 months

In reality it probably dorsn't make much difference with normal road driving at our ambient temperatures.

Most dealers use.longlife irrespective of service regime the car is on.

Unless it's a PD diesel, originally they were advised to use 505.01 oil for fixed servicing, castor edge 5w40 turbo diesel meets this spec.

Last time I asked at a dealership they were using 5w30 spec 507.00 for either type of service. 5w30 castrol edge with "VW/audi" on the bottle meets this spec.

Yup, been single spec for a while now.

The differences come down to what is done at each 'service' (although even that's fairly confusing these days).

i use the long life 50700 oil,
i don it myself every summer and if i can i leave it as long draining as i possibly can,
dont know if it works or not, but ive always doen uit and the engines are always ok,

oh and i tend to cut my hand as well.

Not sure this is right anymore.

My local VW garage says they use the same oil whether fixed or variable service intervals.

Can't see a garage holding two types of oil in my view :-)

My local skoda dealer doesn't - hence my 2010 PD had to go back for an extra oil change as they'd put it onto the fixed servicing regime which wasn't what I'd asked for (or what it was previously on). MPG has been fairly rubbish ever since however.
