I would like to keep my new Octy 2.0 Tdi for a good few years, and I am anxious to do everything I can to look after the new engine, so the question arises; is 10,000 miles too long a time to run a new engine without an oil change?

 

An argument for an early oil change:

It suggests as early as 20 miles.

 

An argument against:

This argues that the manufacturers know best, and that the metal content left in the oil of a new engine is actually beneficial to the bedding in process.

 

What do you think?

20 miles?!? LMAO!

Just follow the service intervals.

Oh god.  I got a flaming for this.  I'm with you, the first few tens of miles is when most of the bedding in happens. The early oil change is about removing the metal wear particles.  I've read about performance engine builders doing a 5 mile change, then a few hundred mile change, then going to normal ( several thousand mile ) changes.   However.... I won't bother with one they early..... Undecided about one at end of run in though (1500 miles)

Doesn't the service require every 20,000 or 2 years? I found that a bit crazy as with my petrol it is done every service.

Follow the manufacturer's recommendations and you won't go wrong - believe it or not it's why they give them....

Well I am going to do an oil and filter change at 1000 miles on VRS TDi. But I am an old school technician and habits are hard to break.

I'm old school as well, but my last Octavia 1.9 did 190,000 miles in 10 years with variable servicing - 18k to 20k between oil changes from new. Its still going strong....

Will be doing same with new octy 3. Obviously extra oil changes can't do any harm but to me its a waste of money.

but we're talking about a skoda octavia!  Once my 3 free 10k services are out of the way mine will going straight on variable...

Mine was delivered using qi6 variable servicing and that means first service is either at 30.000km or 2 years which ever comes first. This was confirmed by the dealer workshop at deliver of the car. I have no intention of replacing anything before then only topping up as needed. Will be keeping the car for 5 years and the warranty is 5 years so if anything breaks they can have the pleasure of replacing it. However my old cars were also like this(Alfa 159, Fiat Bravo 2008) and no issues with those :-)

You get 5 year warranty in Denmark?

Each to there own. I will still be changing mine at 1000 miles.

Standard is 2 years but with an option to get +3 years or 150.000km for a modest 850£. Cars are very expensive here so I jumped at the opportunity :-)

Ah right, we get 3 years here but we can also extend that.

Variable vs fixed is irrelevant.  This early change discussion is nothing to do with oil degrading!

 

What applies to an engine built by a performance builder applies to all engines, their words.

Your mass produced Octavia isn't running at the point of destruction like a performance engine will be. A performance engine also has to be able to run at max once handed over as ready by the builder.

Fixed, variable, 1st one at 1500 miles, or 5 miles it won't make any difference.

Exactly, these aren't performance engines, even the TSi is a low stressed fairly run of the mill engine, they don't need molly coddling.

5 years warranty is standard In Norway;)

Nowadays it's a 3 year warranty in Sweden ... earlier it was 2 years.

Interesting as my vrs popped up with oil change in 1000 miles yesterday. It's currently sat on around 8600 I believe.

And the early change has nothing to do with stress/load on the engine.  It is purely to remove the wear particles that a a result of bedding in any and every engine. Removing them to prevent risk of further, premature or possibly unusual wear on the engine.

To be fair isn't that what your oil filter is for?

Ooh, you pair will upset a lot of people with these inflammatory comments.

oil filter won't remove particles down to the size that will be created,.  Oil filters only remove relatively large lumps of debris.

The oil filter will trap particles measured in microns, I don't know the exact figures but it is something like 10 microns. There is a mesh/gauze on the oil pump pick up pipe in the sump for any large pieces, plus a magnet. Modern oil only needs changing due to contamination from the combustion process and for the periodic installation of a new filter. If you're worried to this extent about oil then what about gearbox oil changes (manual), its doing the same mileage as the engine, but never gets changed..

Ive read Oil filters typically have 95%+ effectiveness at about 20 microns, 20% ish effectiveness at about 7 microns and the damaging range of particle size is 2 to 20 microns.
